The strongest earthquake in the world today was an M 6.0 (CWB gives this M 6.4) in Taiwan. NEIC reported this earthquake was felt with damage and intensity up to VIII in Taiwan at Tainan with VI in Chiayi, Nantou, Taichung, Yunlin; V in Changhua, Chiayi, Hsinchu, JKaohsiung, Nantou, Pngtung, IV in Taipei, Taoyuan, and III in mainland China in Fujian, Hong Kong, Hangzhou and Hefei among others.
EMSC reported significant shaking in Zhongpu Township, Beigang, Wuri District, Nantun District, Zhudong, Zhongzheng, Da'an, Beitou, Tamsui, and Yuanshan Townships and in Fuzhou Citym China,
TAI reported intensity VI in Chiayi, V in Tainan, Kaohsiung; IV in Chiayi, Yunlin, Taitung, Nantou, Pingtung, Hualien, Changhua, Taichung, Penghu, III in Miaoli, Yilan, Hsinchu; II in Taoyuan, Taipei, and Lienchiang Counties, Taiwan.
A number of aftershocks were recorded - up to 50 at this writing. A fire broke out in a printing facility in Chiayi City but there were no reports
of injuries with this fire.
News reports are that some TSMC, a computer chip maker, closed its plant down due to the
earthquake. Shaking can cause errors in computer chips and adjustment
following earthquakes is often necessary. Initial reports indicate up to 27 injuries in mountainous areas and damage to
items falling. Six were rescued from a collapsed house in Nanxi District in Tainan City. The Zhuwei Bridge was also damaged. The earthquake occurred near local solar midnight and was probably
promoted by strong tidal and/or geomagnetic effects which maximize near this hour.
The last earthquake in Taiwan of M>=6.4 within about 250 km of today's
epicenter occurred on April 4, 2024 as an M 7.4 with an aftershock of M 6.4 on
April 3, 2024. At the time this summary noted:
"A major M 7.4 earthquake damaged much of the Island of Taiwan today. International Press reports indicated that this event and several
strong aftershocks killed at least 7 while injuring more than 700. The quake
occurred about 20 km south of Hualien and damaged and toppled buildings while
causing many damaging landslides. It is the strongest earthquake to hit
Taiwan in at least 25 years - since September 20, 1999 (M 7.7) - the strongest
event in Taiwan in the past 35 years. Major earthquakes have most recently
hit with M>=7.5 in Taiwan on November 14, 1986 (M 7.8); July 24, 1978 (M 8.0); April 24, 1972 (M 7.7) and January 25, 1972 (M 7.7)." (April 3, 2024)
This is the first event in the world of M>=6 since the M 6.8 in Kyushu, Japan
of January 13 and occurred as solar and geomagnetic activity was increasingly
large.
Today's event in Taiwan was coincident with solar flare 6870 - a C2.8
event and may have have been promoted by SFE associated with that flare.

EMSC reported large jolts and objects moving in Guam at Santa Rita and Tamuning.
This is the strongest earthquake near Guam since an M 5.5 on September 14, 2024.
At the time this summary noted:
"An M 5.3 in Guam occurred at a longitude which was at local solar midnight when
this flare peaked and may have been promoted by Solar Flare Effects (SFE).
The strongest earthquake of the day was an M 5.3 in Guam. NEIC reported it was felt with intensity V in Guam at Hagatna Hts; IV in Hagatna, Yona, Santa Rita, Mangilao, Piti, Sinajana and III in Tamuning, Dededo, and Asan.
EMSC reported it was felt as a jolt in Guam at Santa Rita, with violent shaking in Mangilao and Tamuning." (September 14, 2024)
A moderately strong earthquake also shook area of Mindoro and Luzon, Philippines today. This event of M 5.4 was reported by NEIC to have been felt with intensity up to IV in Central Luzon at Mariveles, and in Imus, Southern Tagalog with III in Luzon at Masantol, Olongapo, Subic, Manila, and II in San Marcelinoand in Southern Tagalog, Philippines at Malanday, Noveleta, Prinza, San Pedro Laguna dn Binan.
EMSC reported moderate shaking in Luzon at Laurel, Trece Martires City, Dasmarinas, Batangas City, Imus, Bacoor, Cavitr, Puerto Galera, Las Pinas City, Taguig, Makati, Mandaluyong, Manila, Taytay, Calapan City, Hermosa, Guiguinto, Olongapo, San Fernando City, Coron.
PHIVOLCS reported this event at M 5.5 was felt with intensity IV in Lubang, Occidental Mindoro, III in the City of Makati; Quezon City; City of Taguig; Hermosa, Bataan; Obando, Bulacan, Balayan, City of Calaca, Calatagan, Lemery, Lian, Tuy, Batangas; City of Dasmarinas, Cavite; City of Cabuyao City of San Pedro, Laguna; Cainta, Rizal; Looc, Occidental Mindoro, City of Calapan, Oriental Mindoro. Lesser shaking was felt throughout Mindoro and Luzon.
This is the strongest earthquake in Luzon or Mindoro, Philippines since an M
5.9 on October 1, 2024. At the time this summary noted:
"A major solar flare of X7.1 class (#4540 and 4690) occurred today with the following
parameters (SWPC):

This is the second strongest solar flare recorded by SWPC in the current
solar cycle. An X8.7 was observed on May 14, 2024. The most energetic flare
affecting the earth in the past 10 years was an X9.3 on September 6, 2017.
...
"The third largest earthquake in the world today was an M 5.9-6.0 in Luzon, Philippines.
EMSC reported moderate shaking in Naga City, Philippines for about 10-15 seconds. This event occurred at the beginning of the X7.6 solar flare and may have been promoted
by SFE associated with that flare." (October 1, 2025)
A series of moderately large earthquakes occurred in the southern Mid-Atlantic Ridge today. These earthquakes of M 5.5, 5.1, 4.9, 4.8 and 5.2 among others, were not reported felt in this remote area. This is in the South Atlantic geomagnetic anomaly region and
may have been related to strong solar and/or geomagnetic activity of the past
several days. This is the strongest earthquake within about 250 km of this
epicenter since an M 5.5 and M 5.8 on November 12-13, 2021. At the time this summary noted:
"The strongest earthquake recorded today was an M 5.7 in the Southern Mid-Atlantic
Ridge near the geomagnetic equator. It was probably enhanced by the
recent geomagnetic storm and effects from tides as it occurred within
minutes of local solar midnight, a time when such tidal stresses maximize.
This is the strongest earthquake within about 300 km of this epicenter
in at least 30 years. A series of three events of M 5.7 hit the area
about 300 km south of this in 2013, 2010 and 1999." (November 12, 2021)
This activity in the South Atlantic is located near the antipode of the M 5.5
in Guam today and occurred in the middle of that swarm within about 12 minutes
of the M 5.5 in Guam. They are possibly related to each other or to SFE from
solar flares or geomagnetic effects which maximized today about that time
as the strongest Kp (7) in the past three weeks.
Several moderately strong magnitude (M 5.2-5.5) also occurred today in the area
near Easter Island in the south Pacific. They were not reported felt in this remote area.

"The strongest earthquake in the world today was an M 5.7 in the Santa Cruz Islands north of Vanuatu. There were no felt reports from this earthquake.
The last earthquake in the Santa Cruz Islands within about 200 km of this epicenter
with M>=5.7 was an M 5.7 on March 12, 2023. The last of significantly larger
magnitude was an M 6.0 on November 25, 2021. At the time this summary noted:
"An M 6.0 was also widely felt in the Solomon and Santa Cruz Islands today. NEIC reported maximum intensity VI was felt in the Solomon Islands at Lala, Temptu amd III in Guadalcanal and II in Sola and Luganville, Vanuatu.
The mainshock occurred near local solar midnight and may have been promoted
by strong tidal stresses. It was followed by a series of moderate aftershocks
including those of M 4.9, 4.7 and 4.4 among others. The mainshock of M 6.0
is the strongest earthquake within about 200 km in the Santa Cruz Islands
since an M 6.0 on August 20, 2019. The last in the Santa Cruz Islands
of larger magnitude was an M 7.0 on July 18, 2015. Last year an M 6.6 hit
south of this in northern Vanuatu on May 12, 2020." (November 25, 2021, January 15, 2025)
An earthquake of M 2.6 struck the area of Malibu, Southern California today and was widely felt in the epicentral area.
This is the largest earthquake felt in the U.S. or Canada today.
NEIC reported it was felt with intensity up to IV in the area where wildfires are currently destroying
vegetation and property in the Los Angeles area and have caused up to 27 deaths with a similar number of people missing. Intensity III was reported from
Malibu, Newbury, and Camarillo with II felt in Los Angeles, Agoura Hills, Thousand Oaks, Westlake Village, Santa Ana, Camarillo, Point Mugu, Goleta and Tujunga.
EMSC reported iot was felt as a strong jolt with a loud bang in Westlake Village and a low rattle in Thousand Oaks, California.
This is the strongest earthquake in the Malibu area within about 50 km of
this epicenter since an M 3.8 on November 22, 2024. At the time this summary
noted:
"A moderate earthquake of M 3.8 was widely felt in the region of greater Los Angeles, California near Malibu today. This near-noontime event was reported by NEIC with maximum intensity IV in California at Pacific Palisades, Seal Beach and Ventura; III in Los Angeles, Beverly Hills, Culver City, Downey, El Segundo, Malibu, Manhattan Beach, Palos Verdes Peninsula, Topanga, Marina del Rey, Santa Monica, Harbor City, Lomita, Wilmington, Long Beach, Glendale, Agoura Hills, Calabasas, Caonga Park, West Hills, Encino, Newbury Park, Reseda, Thousand Oaks, Westlake Village, and in general within abouot 100 km of the epicenter in Southern California.
EMSC reported this earthquake at M 3.6 felt in teh area of Los Angeles with moderate intensity. The last earthquake
larger magnitude in this region of Los Angeles occurred as an M 4.7 on September 12, 2024.
Other earthquakes in this area this year occurred as an M 4.1 on January 1, 2024 and February 9, 2024 with M 4.6 and an M 4.4 on August 12, 2024.
This summary has previously noted enhanced seismicity in this region of Los Angeles
this year most recently on September 12, 2024 as:
"The strongest earthquake in the U.S. or Canada today was an M 4.7 in the region of Los Angeles, California.
NEIC received nearly 20,000 felt reports from residents of Southern California. These included reports of intensity V in Malibu, Agoura Hills, Westlake Village, Thousand Oaks, and IV in Calabasas, Oak Park, Newbury Park, West Hills, Woodland Hills, Camarillo, Canoga Park, Simi Valley, Winnetka, Tarzamna, Santa Monica, Moorpark, Santa Monica, Encino, Reseda, Northridge, Los Angeles, Sherman Oaks, Van Nuys, Somis, Marina del Rey, Beverly Hills, Studio City, Valley Village, North Hollywood, Universal City, Hermosa Beach among others. Intensity III was felt as far as 150 km from the epicenter in places such as San Bernardino and Camp Pendleton, California with II shaking as far as 600 km from the epicenter in Arizona, Nevada, Oregon and Colorado among others.
The last earthquake in the Los Angeles with M>=4.7 within about 100 km of today's
M 4.7 epicenter occurred as an M 5.1 on August 20, 2023 and prior to that an M 5.1 on
March 29, 2014 and M 4.7 on May 18, 2009, the last such event in the Simi Valley
near Los Angeles.
...
EMSC reported a regional foreshock of M 2.2 in eastern Los Angeles several hours earlier was felt with moderate sound an intensityin Fontana and Rancho Cucamonga, California.
Today's M 3.8 in Los Angeles occurred near local solar noon and at the height
of solar flares 610 (C3.9) and 640 (M1.0) with data listed below from SWPC and
may have been triggered by SFE from those flares which occurred within minutes of
local solar noon. This coincidence suggests the area is under considerable
triggerable strain and a larger magnitude solar flare near local solar midnight
or noon could trigger a stronger regional earthquake." (November 22, 2024)
Tropical Cyclone Dikeledi passed over the antipode to this epicenter two days
ago and may have helped promote today's event in the Malibu area as reported at the time in this summary:
"Tropical Cyclone Dikeledi (07S) continued today in the area of the south Indian Ocean south of Madagascar with winds up to 65 kts. It is expected to track to the south and east over the next several days. This cyclone will reach an area of 34S 62W with winds up to about 100 kts around January 17-18, 2025. At this time it will be antipodal to Los Angeles, California and could promote enhanced seismicity in that area at that time. Coincidences such as this have been seen in seismicity in Southern California often after strong fire events such as is now happening in the area." (January 17-18, 2025)
Today's earthquake in Malibu occurred near local solar midnight and may also have
been promoted by tidal stresses which maximize near this hour.
NEIC reported an earthquake of M 4.7 in Argentina was felt with moderate intensity up to IV in the area(s) of Argentina at San Juan.
NEIC reported an earthquake of M 2.5 in Northern California was felt with moderate intensity up to II-III in the area(s) of Northern California at Folsom.
NEIC reported an earthquake of M 3.3 off the coast of Northern California was felt with moderate intensity up to III in the area(s) of Northern California at Hydesville, Petrolia, Whitethorn and II in Eureka, Ferndale, Fortuna, Loleta, Rio Dell.

FAR-FIELD AFTERSHOCKS LIKELY AFTER M 6.8 IN KYUSHU, JAPAN
EARTHQUAKE SUMMARY FOR JANUARY 13, 2025
A strong to major earthquake of M 6.8-6.9 hit the area of Kyushu, Japan today. The quake shook buildings and may have generated a tsunami, but no reports of major damage or high tsunami waves have been officially made. The largest tsunami wave was measured at 7.8 inches in Miyazaki City. The quake was felt in Miyazaki and at least one minor injury was reported by a person who fell down a flight of stars during the quake. The tsunami warning has been lifted. NEIC reported this earthquake was felt with intensity IV (Some damage) at Miyazaki, VII in Saiki, Oita; VI in Junitomi, Miyazaki; V in Kanoya, Kagoshima dns Koshi, Kumamoto and with IV in Oita, Osaka, Ehime Fukuoka, Hiroshima, Kagoshima, Shizuoka, South Korea. Eruptions of Sakurajima Volcano are expected after the M 6.9 to increase in frequencies and amplitude. Sakurajima is located in Kyushu and is among the most active volcanoes in Japan. This epicenter in Kyushu is at the sixth node (60 degrees) from the M 7.4 in Vanuatu of December 17, 2024 and may have been promoted by energy from that source. It is also at 108 degrees from Michoacan, Mexico where an M 6.2 occurred earlier in the day. This is in the zone where core-mantle reflections of seismic waves return to the surface and appear to help trigger enhanced seismicity at this distance from mainshocks.
The relation to Vanuatu had been noted when that event occurred as:
"Node 6 (60 degrees)
Vanuatu to Honshu, Japan, Kuril Islands, Taiwan, Sumatra, Pacific-Antarctic Ridge, Java, Kyushu, Japan," (December 17, 2024)
The last earthquake of M>=6.8 in the area of Kyushu, Japan within about 200 km of today's epicenter occurred on August 8, 2024 with M 7.1 and today's event may be an aftershock of that. An M 7.0 also hit the region on April 15, 2016. At the time this summary noted:
"A number of active volcanoes exist on Kyushu including Unzen, Aso, Sakurajima, Kuju, Tsurumi and Kirishima. The earthquakes in this area over the past two days may change the plumbing for some of these volcanoes leading to changes in their volcanism. Several of these including Kirishima have been active in the past two months. Kirishima had aminor eruption with volcanic earthquakes on March 1, for example. The nearest volcanoes to the current earthquakes are Aso and Unzen about 30-40 km from these events. Mount Aso erupted today sending ash and smoke 100 meters into the air. This eruption seriously damaged the Aso Shrine with a number of buildings flattened on the ground. A large gate collapsed. There were no tsunamis associated with this land-based earthquake and no problems were reported from nearby nuclear power plants.
The last earthquake within about 200 km of today's mainshock in Kyushu with M>=7 occurred 20 years ago on October 19, 1996 (M 7.0) about 200 km southwest of today's epicenter. Earthquakes of M>=7 have generally followed the solar cycle with approximately 11 and/or 22 year intervals in recent history. This included major earthquakes in 1996, 1984, 1961, 1941, 1922-1923, 1904, 1899, 1857. As it has been 20 years since the last such event, the quasi-periodicity of these quakes appear in tact." (April 15, 2016)
Moderate far-field aftershocks are likely following the M 6.8 in Kyushu in the following areas:
Antipodal (~180 degrees)
Kyushu to
Outer shadow zone edge (141-148 degrees)
Kyushu to Central Peru, Central Atlantic, South Atlantic,
Node 3 (120 degrees)
Kyushu to Nicaragua, North Atlantic, Honduras, Guatemala, Vancouver, East Pacific Rise,
P- and S- shadow zone edge and node 7 (101-110 degrees)
Kyushu to Jalisco, Michoacan, Mexico, North Atlantic, Madeira Islands, Tennessee, North Carolina, western Mexico, Missouri, Pennyslvania,
Node 4 (90 degrees)
Kyushu to Reykjanes Ridge, France, Imperial, Baja, California, Utah, Arizona
Node 5 (72 degrees)
Kyushu to Nunavit, Tonga/Fiji,
Node 6 (60 degrees)
Kyushu to Vanuatu, Turkmenistan,
Node 7 (52 degrees)
South Sandwich Islands to Southern Peru,
Kyushu to Alaska Peninsula, So. Sumatra, Tennant Creek, Solomon Islands, Northern Australia,
Node 8 (45 degrees)
Kyushu to New Britain, Bengkulu, Indonesia, Fox Islands, Aleutians,
Forecast 168920 had expected this activity in Kyushu was likely within about 100 km around January 13, 2025.

The latest tolls from the M 7.1 in Xizang, China of January 7, 2025 indicate that at least 126 were killed and 338 injured in Tibet. At least 47,000 have been relocates as harsh winter conditions make rescue and survival difficult. Moderate aftershocks of M 5.1 and 5.1 shook the area today. NEIC reported
intensity III shaking in Shiliguri, Bangla, India with II at Rangpo, Sikkim, Indian an II in Nepal at Tribuvannagar, Kathmandu and Dhulikhet.
These earthquakes in Kyushu and China may have been promoted by the new moon of January 13 as noted in this summary as:
The full moon will arrive on January 13, 2025 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/Kermadec Islands, New Zealand to the Balleny Islands and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this full moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this full moon are moderate to high.
The strongest earthquake in the U.S. or Canada today was an M 4.5 in Nunavut, Canada near Devon Island and Resolute, Canada. It was not reported felt in this remote area. This is the strongest earthquake within about 300 km of this epicenter since an M 4.9 on November 23, 2020. At the time this summary noted:
"The strongest earthquake in the U.S. or Canada today was an M 4.9-5.3 in northern Canada near Somerset and Prince of Wales, Islands, Nunavut. Earthquakes Canada reported the mainshock was felt in the epicentral area and was followed by a series of aftershocks. Today's event near the north geomagnetic pole occurred at the height of a strong geomagnetic storm which reached AP 45 at high latitudes early on November 23, the strongest in nearly two months. The only other event of M>=5.3 in the past 30 years in this general region was an M 6.0 on January 8, 2017. At the time this summary noted in this regard:
"The strongest earthquake in the U.S. or Canada or the world today occurred near the North Geomagnetic Pole (NGP) near Devon Island in northern Canada with M 5.8-6.1. This is a remote area and while this event was reported felt by five people, it was not damaging and no tsunami was reported. There are no previous reports of any earthquake in the area of M>=5.8. Two events of M 5.4-5.7 hit the same general area on December 13, 1987 and March 8, 1963. The unusually large magnitude of this earthquake and the location near the North Geomagnetic Pole suggest some promotional effects from the current geomagnetic storms at high latitudes which have been ongoing for the past week. Today's event may also reflect loss of ice weight as the area responds to regional warming conditions. The loss of ice load can cause rebound in the land beneath."

Moderate earthquakes continued today in the region of Ethiopia. These are being felt in the Awash and Afar Triangle regions of Ethiopia and in Addis Ababa. There is some concern that they may lead to the eruption of the volcano Mount Dofan and/or the collapse of a major dam. Many buildings have collapsed and left people homeless. To protect the population evacuations have been proceeding since December. This has led to mere survival conditions among many of the evacuated as water and food are in short supply. There is fear of a cholera epidemic. Magma is spreading through a large fissure about 50 km long and roads are becoming impassable. Today's events included an M 4.8 felt with intensity III in Addis Ababa.
News from Xizang China (Tibet) indicates that the recent earthquakes there, starting with the M 7.1 on January 7, 2025 has damaged at least two Buddhist monasteries and left a number of nuns and monks hurt (Reuters). Monasteries are a major cultural factor in Tibet. Part of the Dzongbu Temple collapsed and rescuers pulled several nuns out of the rubble alive. Also affected was the Sengar Chode Monastery founded in 1541. At least 3,600 homes collapsed during the earthquakes which left at least 126 people dead. Aftershocks continued in the region today including two of M 5.1 felt with light intensity in Kathmandu, Nepal. These earthquakes are located at the fourth node (90 degrees) from the M 7.4 in Vanuatu of December 17, 2024 and are likely FFA from that event.
Forecast 168960 had expected enhanced seismicity in Xizang at this aftershock
zone was likely around January 13, 2025.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

An earthquake of M 3.5 was widely felt today in the area of Texas and Louisiana. NEIC reported maximum
shaking of V at Allen Texas with IV in Louisiana at Mooringsport, Shreveport and Barksdale, AFB. Intensity II was felt in Bossier City, and in Texas at Karnack, Kilgore, with lesser shaking in Louisiana at Belcher, Benton, Greenwood, Bossier City an Stephens, Arkansas.
Along with a similar M 3.5 on January 27, 2024 this is the largest earthquake
in the region of Louisiana within about 100 km of today's epicenter in at least
35 years. A series of earthquakes of M 3.0 and M 3.1 began in this area on December
19, 2024 and was described in this summary at the time as:
"NEIC reported earthquakes of M 2.5 and M 3.3 in the Texas-Louisiana border was felt with intensity up to IV in the area(s) of the Texas-Louisiana border at Kilgore, Texas with III in Lousiana at Homer, Shreveport, Bossier City and II in Texas at Gunter, Karnack.
It is located near 103 degrees from the M 7.4 in Vanuatu and is a likely FFA event.
This was reported in the last issue of this summary as:
"The most unusual earthquake in the U.S. or Canada today was an M 3.3 on the Louisiana and southeastern Texas border.
NEIC reported it was felt with maximum intensity IV in Louisiana at Mooringsport, Oil City, Shreveport and in Henderson, Texas. Lesser shaking was reported from Louisiana at Belcher, Benton, Vivian, Barksdale AFB, Bossier City, and Texas at Jefferson, Karnack, Kilgore, Lufkin.
This epicenter is located at 105 degrees from the M 7.4 in Vanuatu of December
17 and appears to be an FFA of that event at the fifth node and p- and s- shadow
zone boundary as noted in previous issues of this summary:
"Inner shadow zone edge (101-110 degrees)
Vanuatu to Peru, Western Texas, Missouri, Kyrgyzstan, Scotia Sea, Central Chile, Arctic Ocean, Pakistan, Xinjiang, China, Oaxaca, Chiapas, Mexico, Guatemala, Tajikistan, South of Africa, South Sandwich Islands, Uzbekistan, Pakistan, Mexico, Oklahoma, Hindu Kush," (December 17-19, 2024)
This earthquake occurred in a region which antipodal to Tropical Cyclone Dikeledi (Currently dissipating at the antipode
of Louisiana near 34S 90E) and was probably promoted by antipodal effects
from that source as described in the previous issue of this summary:
"Tropical Cyclone Dikeledi (07S) continued today in the area of the south Indian Ocean south of Madagascar with winds up to 55 kts. It is expected to track to the south and east over the next several days. This cyclone will reached an area of 34S 62W with winds up to 100 kts today but no noticeable effect was observed in the seismicity of southern California. A second cyclone is expected to take a similar path in the South Indian ocean in the next 10 days and could also bring a moderate increase in seismicity to southern California. TC Dikeledi will continue on at about 34 South latitude for several more days eventually losing strength and dissipating near 34S 85E. In the meantime it will pass over areas nearly antipodal to Western Texas, Oklahoma, Louisiana and Tennessee which currently show active seismicity and could help promote enhanced seismicity in these regions in the next two days." (January 18, 2025)
Other earthquakes in the Central U.S. today antipodal to Dikeledi occurred
as an M 2.4 in Tennessee and as a series in Oklahoma and Texas.
Coincidentally a strong tropical Cyclone (Candice) was positioned near the
same location as today in the South Indian Ocean at the time of the January 27, 2024
M 3.5 in Louisiana as noted in this summary at the time:
"Tropical Cyclone Candice (08S) formed today in the South Indian Ocean with winds up to 40 kts. It is moving to the south and is expected to reach a position antipodal to southern California around January 29-30 if it does not dissipate in the next day. If it is still active then, this is the most likely time for a triggered earthquake from antipodal energy associated with this storm in Southern and Baja California. This is likely to be at most a light to moderate event. Local enhancement of seismicity in this region of the South Indian Ocean is not expected to be strong with this storm. This system is currently located at 20S 57E near Mauritius but is not expected to signifiancely affect regional seismicity. The antipode is at 20N 122W west of the Gulf of California where a series of moderate earthquakes is occurring at this time." (January 27, 2024)
An unsually large M 3.7 shook areas of Western Australia today. This event
occurred near local solar noon as an M-Class solar flare was beginning
and may have been promoted by SFE associated with that flare.
Initial flare data for this event from SWPC are:

This earthquake in western Australia coincided in time with the formation
of Tropical Cyclone Sean at this latitude and about 10 degrees north of
the epicenter in Western Australia and may have also been enhanced by
energy associated with that nearby storm. This had been noted in this
summary as:
"Tropical Cyclone Sean formed today north of Western Australia with winds up to 65 kts. It is expected to skirt the northern coastline of western Australia over the next several days reaching maximum winds of 110 kts. This storm may enhance seismicity in western Australia while in the region. The antipode is at 19-20N 64-65W - an active seismic area of the Virgin Islands and Puerto Rico. Some antipodally enhanced seismicity is likely in this area in the next several days." (January 19, 2025)
An M 3.7 also occurred today in the area of Hawthorne, Nevada. NEIC reported it was was felt with intensity up to II in Hawthorne and Glenbrook, Nevada.
The strongest earthquake in the U.S. or Canada today was an M 4.7 in the Fox Islands, Aleutians, Alaska. NEIC reported it may have been felt in Alaska.

---- ------- ---------- -------- ----- ------ ------- ---------------
TC DIKELEDI 2025-01-19 00:00 UT 34.0S 90.8E 045 kts South Indian Ocean
Tropical Cyclone Dikeledi (07S) continued today in the area of the south Indian Ocean southeast of Madagascar with winds up to 45 kts. It is expected to track to the south and east over the next several days. This cyclone will reached an area of 34S 62W with winds up to 100 kts today but no noticeable effect was observed in the seismicity of southern California. A second cyclone is expected to take a similar path in the South Indian ocean in the next 10 days and could also bring a moderate increase in seismicity to southern California. TC Dikeledi will continue on at about 34 South latitude for several more days eventually losing strength and dissipating near 34S 85E. In the meantime it will pass over areas nearly antipodal to Western Texas, Oklahoma, Louisiana and Tennessee which currently show active seismicity and could help promote enhanced seismicity in these regions in the next two days.
TROPICAL CYCLONE SEAN (10S)
---- ------- ---------- -------- ----- ------ ------- ---------------
TC SEAN 2025-01-19 00:00 UT 19.5S 116.1E 065 kts North of Western Australia
Tropical Cyclone Sean formed today north of Western Australia with winds up to 65 kts. It is expected to skirt the northern coastline of western Australia over the next several days reaching maximum winds of 110 kts. This storm may enhance seismicity in western Australia while in the region. The antipode is at 19-20N 64-65W - an active seismic area of the Virgin Islands and Puerto Rico. Some antipodally enhanced seismicity is likely in this area in the next several days.

January 18, 2025
It was a generally quiet day in global seismicity today. The strongest earthquakes
in the world occurred as an M 5.0 in Mindanao, Philippines. Several cyclones
including Dikeledi in the South Indian Ocean and Sean north of western Australia
are positioned so that they may enhance antipodal seismicity and regional
seismicity but this has not yet been observed.
NEIC reported an earthquake of M 5.0 in Mindanao, Philippines was felt with moderate intensity up to II-III in the area(s) of Mindanao, Philippines in Caraga at Bislig and Tagbina and in Ormos, Eastern Visayas.
PHIVOLCS reported intensity V in Talacogon, Agusan del Sur; IV in Rosario, Benawan, Esperanza, San Francisco, La Paz, and City of Bayugan, Agusan del Sur and Barobo, Surigao del Sur and with intensity III in Loreto and Prosperidad, Agusan del Sur. Also felt with intensity II in Surigao del Sur, Miamis, Oriental, Davao del Norte, Davao Oriental, Davao de Oro, Bukidnon and Cagayan del Oro.
Tropical Cyclone Dikeledi (07S) continued today in the area of the south Indian Ocean south of Madagascar with winds up to 55 kts. It is expected to track to the south and east over the next several days. This cyclone will reached an area of 34S 62W with winds up to 100 kts today but no noticeable effect was observed in the seismicity of southern California. A second cyclone is expected to take a similar path in the South Indian ocean in the next 10 days and could also bring a moderate increase in seismicity to southern California. TC Dikeledi will continue on at about 34 South latitude for several more days eventually losing strength and dissipating near 34S 85E. In the meantime it will pass over areas nearly antipodal to Western Texas, Oklahoma, Louisiana and Tennessee which currently show active seismicity and could help promote enhanced seismicity in these regions in the next two days.
NEIC reported an earthquake of M 3.2 in Central California was felt with moderate intensity up to II-III in the area(s) of Central California at Glendale.
NEIC reported an earthquake of M 3.0 in Northern Alaska was felt with moderate intensity up to II-III in the area(s) of Central Alaska at Tanana and Galena.
NEIC reported an earthquake of M 2.8 in Kettleman City, California was felt with moderate intensity up to II-III in the area(s) of Kettleman City, California at Gilroy.
NEIC reported an earthquake of M 3.5 in Puerto Rico was felt with moderate intensity up to II-III in the area(s) of Puerto Rico in Salinas and Gurabo.
This epicenter is nearly antipodal to a new Tropical Cyclone (TC Sean) forming today
north of Australia and may have been promoted by antipodal focusing of energy
from that storm.
NEIC reported an earthquake of M 2.8 in Central California was felt with moderate intensity up to IV in the area(s) of Central California at Santa Clara and III at Ben Lomond, Los Gatos, Milpitas, San Jose, Oakdale, Grass Valley, San Frncisco, Albanu, Campbell, and II in Los Gatos, Santa Clara, Santa Cruz, Stockton, Vacaville and Sunnyvale.

STRONG EARTHQUAKE SHAKES KYUSHU, JAPAN
EARTHQUAKE SUMMARY FOR JANUARY 12, 2025
A strong to major earthquake of M 6.8-6.9 hit the area of Kyushu, Japan today. The quake shook buildings and may have generated a tsunami, but no reports of major damage or high tsunami waves have been officially made. The largest tsunami wave was measured at 7.8 inches in Miyazaki City. The quake was felt in Miyazaki and at least one mine injury was reported by a person who fell down a flight of stars during the quake. The tsunami warning has now been lifted but some evacuations may still occur. NEIC reported this earthquake was felt with intensity IV (Some damage) at Miyazaki, VII in Saiki, Oita; VI in Junitomi, Miyazaki; V in Kanoya, Kagoshima dns Koshi, Kumamoto and with IV in Oita, Osaka, Ehime Fukuoka, Hiroshima, Kagoshima, Shizuoka, South Korea. This epicenter is at the sixth node (60 degrees) from the M 7.4 in Vanuatu of December 17, 2024 and may have been promoted by energy from that source. It is also at 108 degrees from Michoacan, Mexico where an M 6.2 occurred earlier in the day. This is in the zone where core-mantle reflections of seismic waves return to the surface and appear to help trigger enhanced seismicity at this distance from mainshocks.
The relation to Vanuatu had been noted when that event occurred as:
"Node 6 (60 degrees)
Vanuatu to Honshu, Japan, Kuril Islands, Taiwan, Sumatra, Pacific-Antarctic Ridge, Java, Kyushu, Japan," (December 17, 2024)
The last earthquake of M>=6.8 in the area of Kyushu, Japan within about 200 km of today's epicenter occurred on August 8, 2024 with M 7.1 and today's event may be an aftershock of that. An M 7.0 also hit the region on April 15, 2016. At the time this summary noted:
"A number of active volcanoes exist on Kyushu including Unzen, Aso, Sakurajima, Kuju, Tsurumi and Kirishima. The earthquakes in this area over the past two days may change the plumbing for some of these volcanoes leading to changes in their volcanism. Several of these including Kirishima have been active in the past two months. Kirishima had aminor eruption with volcanic earthquakes on March 1, for example. The nearest volcanoes to the current earthquakes are Aso and Unzen about 30-40 km from these events. Mount Aso erupted today sending ash and smoke 100 meters into the air. This eruption seriously damaged the Aso Shrine with a number of buildings flattened on the ground. A large gate collapsed. There were no tsunamis associated with this land-based earthquake and no problems were reported from nearby nuclear power plants.
The last earthquake within about 200 km of today's mainshock in Kyushu with M>=7 occurred 20 years ago on October 19, 1996 (M 7.0) about 200 km southwest of today's epicenter. Earthquakes of M>=7 have generally followed the solar cycle with approximately 11 and/or 22 year intervals in recent history. This included major earthquakes in 1996, 1984, 1961, 1941, 1922-1923, 1904, 1899, 1857. As it has been 20 years since the last such event, the quasi-periodicity of these quakes appear in tact." (April 15, 2016)
Forecasts 168892 and 168920 had expected today's event in Kyushu was possible within about 100 km around January 12-13. 2025.

The latest tolls from the M 7.1 in Xizang, China of January 7, 2025 indicate that at least 126 were killed and 338 injured in Tibet. At least 47,000 have been relocates as harsh winter conditions make rescue and survival difficult.
Moderate aftershocks of M 5.1 and 5.1 shook the area today. NEIC reported
intensity III shaking in Shiliguri, Bangla, India with II at Rangpo, Sikkim, Indian an II in Nepal at Tribuvannagar, Kathmandu and Dhulikhet.
These earthquakes in Kyushu and China may have been promoted by the new moon of January 13 as noted in this summary as:
The full moon will arrive on January 13, 2025 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/Kermadec Islands, New Zealand to the Balleny Islands and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this full moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this full moon are moderate to high.
Forecasts 168960 and 168895 had expected continuing aftershocks in this area were likely around January 13-14, 2026.

Moderate aftershocks also continued today in the region of Michoacan, Mexico following an M 6.2 there described in the previous issue of this summary as:
"The strongest earthquake in the world today was an M 6.2 in Jalisco, Western Mexico. NEIC reported it was felt with minor damage at intensity VI levels in Jalisco, Mexico at El Verde and Pihuamo and IV in El Linon, , Tamazula and Teocuitatlan de Corona, Jalisco and in Comala, Colima. Intensity IV was reported from Aguscalientes, Armeria, Colima, Cuauhtemoc, Manzanillo, Suchitlan, Guadalajara, Ixtapa, Las Pintas, Neuvo Mexico, Ocotlan and many others. It was lightly felt as far as Los Angeles, California and in Nayarit, Guerrero and Mexico City, Mexico. EMSC reported strong shaking in Mexico at Chapala, Barra de Navidad, San Agustin, Guadalajara, Zapopan, Te[atitlan De Morelos, Etzatland, Puerto Vallarta, Azcapotzalco, and Mexico City. Several moderate aftershocks were also felt in this area of Mexico. This event occurred near local solar midnight and may have been promoted by strong tidal stresses which maximize near this hour. This event at M 6.2 is the strongest in Michoacan, Mexico within about 200 km of this epicenter since an M 6.8 on September 22, 2022 - an aftershock of an M 7.6 of September 19, 2022 and may be the strongest aftershock to date of those events. At the time this summary noted:
"NEIC reported the earthquake in Michoacan, Mexico was felt with strong intensity IX in Michoacan at Coshuayana and VUU in Coalcoman. It was also felt with intensity VI in Colima at Colima, Cuauhtemoc, Villa de Alvarez, Colima, Suchitlan, and in Tecalitalan and Pihuamo, Jalisco, Mexico. Foreshocks hit within about 150 km of this epicenter with M 6.1 of September 2, 2022 and M 5.9 on August 13, 2022. A national earthquake drill commemorating the M 8.1 on September 19, 1985 occurred about an hour before this earthquake. It is possible that this drill helped save many from death or injury from today's earthquake as they were outdoors and aware of the possibility of a quake at that time. A tsunami warning was issued and later revised. Fluctuation of ocean up to about a foot (0.3 meters) were reported. Gauges in Mexico registered maximum tsunami height of 0.8 m in Manzanillo, 0.5 m in Zihuatanejo and 0.1 in Acapulco. Tsunami waves of 0.12 meters (0.4 feet) were also reported in the Galapagos Islands with similar waves in Lazaro Cardenas, Mexico, Zihuatanejo and Puerto Vallarta, Mexico by PTWC. At least one person was killed when a facade of a department store fell on a man in Manzanillo. A second was killed when falling portions of a Mall hit him. At least 7 were injured but the toll continues to rise as rescue workers begin their work. At least 20 hospitals in Michoacan were damaged. Damage was also reported to hotels, medical facilities, churches and colleges in Coalcoman. More than a million people lost power in the quake. Earthquakes within about 300 km of today's epicenter of M>=7.2 hit this area on April 18, 2014 (M 7.2), January 22, 2004 (M 7.5), January 11, 1997 (M 7.2). The only earthquake of larger magnitude in this area in the past 30 years was an M 8.0 on October 8, 1995. An M 8.1 also occurred in this region of Michoacan exactly 37 years ago - on September 19, 1985. This was widely damaging with more than 35,000 acknowledged deaths especially in the region of Mexico City. It may be the most deadly earthquake recorded in the region of North and Central America since records began. Another deadly earthquake hit this area on September 19, 2017. That event of M 7.1 also caused much damage and deaths in the area." (September 19, 2022)
This epicenter in Michoacan is near the antipode of a tropical storm in the South Indian Ocean. When this storm began this summary noted potential seismic triggering in the Jalisco area of Mexico from antipodal triggering as:
"A tropical cyclone may be forming in the South Indian Ocean east of Madagascar. This system is currently located near 15S 68E and moving to the west at 19 kts with winds up to 33 kts. It could enhance regional seismicity along the ridge lines in the South Indian Ocean area and could affect the antipodal seismicity near the Gulf of California at 15N 112W. Later it could affect seismicity in southern California as it approaches the antipode to that area." (January 10, 2025)
This storm (TC Dikeledi) will be near the antipode to Los Angeles, California around January 18 and could induce enhanced seismicity in that region near that time." (January 12, 2025)

An M 3.6 earthquake occurred today in the San Francisco Bay area of California.
NEIC reported an earthquake of M 3.5-3.6 in San Francisco Bay, California was widely felt with moderate intensity up to IV in the area(s) of San Francisco Bay, California at Stinson Beach and Santa Cruz and III in Carmel, San Francisco, Benicia, Clayton, Concord, Pleasant Hill, Crockett, Danville, El Cerrito, Hercules, Lafayette, Martinez, Napa, Pinole, Pittsburg, Rodeo, San Ramon, Vallejo, Walnut Creek, Oakland, Emeryville, Berkeley, El Sobrante, Richmond, San Pablo among others. This follows similar activity in the area in the past several days and occurred near local solar noon, perhaps intensified by the full moon of January 13. This seismicity was discussed in previous issues of this summary as:
"Earthquakes of M 2.9 and M 3.6, M 2.5, off central California near San Francisco were felt in the San Francisco area today. Several were widely felt with maximum intensity IV in San Francisco; III in Burlingame, Portola Valley, Sunnyvale, San Mateo, Elk Cerrito, Oakland and II in Brisbane, Daly City, Half Moon Bay, Millbrae, Pacifica, Redwood City, San Bruno, Alameda, Albany, Richmond, among others. EMSC reported these events were felt in San Francisco, San Mateo, Oakland, San Bruno, Pacifica as a short thud. The event of M 3.4-3.6 off shore San Francisco is the strongest recorded within about 50 km of this epicenter since an M 3.7 on October 28, 2023. At the time this summary noted:
"A light M 2.9 in Northern California south of the San Francisco Bay area occurred following the M 5.1 in SE Alaska and may have been triggered by it. The California quake was reported by NEIC to have been felt with intensity II-III in San Jose, Santa Clara, Los Gatos, Mountain View, Boulder Creek, Walnut Creek and San Francisco. This activity occurred during a minor geomagnetic storm in conjunction with the full moon and lunar eclipse today and was probably promoted by stresses associated with those two factors. The last earthquake in San Francisco of similar size was an M 3.6 on December 17, 2022. At the time this summary noted:
"Today's event of M 3.6 is the strongest within the San Francisco Bay area of
California within about 50 km of this epicenter since an M M 4.1 on June 2, 2022 and prior to that an M 3.9 on June 20, 2021 and an M 4.5 on October 15, 2019. At the time of the last such event on June 2, 2022, this summary noted:
"An earthquake of M 4.2 also shook the region of San Francisco, California today. NEIC reported maximum intensity IV in Sulsun City with intensity III throughout most of the rest of the San Francisco Bay area including at Concord, Benicia, Pittsburg, Birds Landing, and Pleasant Hill among others. This is the strongest earthquake in the San Francisco Bay area of California since an M 4.5 on October 15, 2019 and prior to that events of M 4.2-4.3 on July 16, 2019 and January 4, 2018. The last earthquake of significantly larger magnitude in the San Francisco Bay area was an M 6.0 in the Napa area on August 24, 2014.
These are the only events of M>=4.2 in the San Francisco area in the past 13 years." (December 17, 2022, June 2, 2022, October 28, 2023, January 11, 2025)

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

The full moon arrived on January 13, 2025 at 22:27 UT. Longitudes which were at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/Kermadec Islands, New Zealand to the Balleny Islands and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this full moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this full moon are moderate to high.

The strongest earthquake in the world today was an M 5.7 in the Santa Cruz Islands north of Vanuatu. There were no felt reports from this earthquake.
The last earthquake in the Santa Cruz Islands within about 200 km of this epicenter
with M>=5.7 was an M 5.7 on March 12, 2023. The last of significantly larger
magnitude was an M 6.0 on November 25, 2021. At the time this summary noted:
"An M 6.0 was also widely felt in the Solomon and Santa Cruz Islands today. NEIC reported maximum intensity VI was felt in the Solomon Islands at Lala, Temptu amd III in Guadalcanal and II in Sola and Luganville, Vanuatu.
The mainshock occurred near local solar midnight and may have been promoted
by strong tidal stresses. It was followed by a series of moderate aftershocks
including those of M 4.9, 4.7 and 4.4 among others. The mainshock of M 6.0
is the strongest earthquake within about 200 km in the Santa Cruz Islands
since an M 6.0 on August 20, 2019. The last in the Santa Cruz Islands
of larger magnitude was an M 7.0 on July 18, 2015. Last year an M 6.6 hit
south of this in northern Vanuatu on May 12, 2020." (November 25, 2021)
NEIC reported an earthquake of M 3.0 in Southern Alaska was felt with intensity up to II-III in the area(s) of Southern Alaska at Anchorage and Tyonek.
NEIC reported an earthquake of M 5.0 in Leyte, Philippines was felt with intensity up to V in the area(s) of Leyte, Philippines at San Isidro and IV in Palarao, Eastern Visayas with II in the Visayas at Logan, Tangke, Naga, Cebu and Tugbong.
NEIC reported an earthquake of M 2.7 in Central California was felt with intensity up to II in the area(s) of Central California at Caliente.
NEIC reported an earthquake of M 3.0 in Southern California was felt with intensity up to III in the area(s) of Southern California at Borrego Springs, Redlands and II in Imperial Beach, Ramona, La Quinta, Rancho Mirage and Thermal.
NEIC reported an earthquake of M 5.0 in Vanuatu was felt with intensity up to III in the area(s) of Vanuatu at Vila Shefa.
EMSC reported an earthquake of M 2.2 in Virginia was felt with moderate intensity up to II-III in the area(s) of Virginia at Glen Allen, Henrico, Short Pump.
BMG reported an earthquake of M 5.1 in Southern Sumatra was felt with intensity up to IV in the area(s) of Southern Sumatra in Kab. Musi Rawas at Tugumulyo, Purwodadi, Sumber Harta; in Kota Lubuk Linggau; Kap Purworejo Groboganand Pasuruan at Purwodadi. Also felt with intensity III in Kab Sarolangun, Lahat, Musi Rawas, Lubuk, Rejand, Lebong, Kapahiand and Tasikmalaya with intensity II throughout much of Sumatra.
This follows an antipodal earthquake of M 5.7 in Colombia of January 11, 2025
Antipodal triggering in Sumatra from that source was described in this summary at the time
as:
"This epicenter (in Colombia) is at the exact antipode of an M 5.3 which hit south of Sumatra two days ago and may
have been promoted or triggered by that event. Frequent readers of this
summary know that two epicenters are antipodal if their latitudes are
the same and in opposite hemispheres (6N and 6S in the current pair)
and their longitudes add to 180 and are in opposite hemispheres (78W and
102E in the current pair). Further activity in Sumatra near this epicenter
is likely in the next several days." (January 11, 2025)

STRONG EARTHQUAKE IN JALISCO, MEXICO
EARTHQUAKE SUMMARY FOR JANUARY 11, 2025
The strongest earthquake in the world today was an M 6.2 in Jalisco, Western Mexico. NEIC reported it was felt with minor damage at intensity VI levels in Jalisco, Mexico at El Verde and Pihuamo and IV in El Linon, , Tamazula and Teocuitatlan de Corona, Jalisco and in Comala, Colima. Intensity IV was reported from Aguscalientes, Armeria, Colima, Cuauhtemoc, Manzanillo, Suchitlan, Guadalajara, Ixtapa, Las Pintas, Neuvo Mexico, Ocotlan and many others. It was lightly felt as far as Los Angeles, California and in Nayarit, Guerrero and Mexico City, Mexico. EMSC reported strong shaking in Mexico at Chapala, Barra de Navidad, San Agustin, Guadalajara, Zapopan, Tetatitlan De Morelos, Etzatland, Puerto Vallarta, Azcapotzalco, and Mexico City. Several moderate aftershocks were also felt in this area of Mexico. This event occurred near local solar midnight and may have been promoted by strong tidal stresses which maximize near this hour. This event at M 6.2 is the strongest in Michoacan, Mexico within about 200 km of this epicenter since an M 6.8 on September 22, 2022 - an aftershock of an M 7.6 of September 19, 2022 and may be the strongest aftershock to date of those events. At the time this summary noted:
"NEIC reported the earthquake in Michoacan, Mexico was felt with strong intensity IX in Michoacan at Coshuayana and VUU in Coalcoman. It was also felt with intensity VI in Colima at Colima, Cuauhtemoc, Villa de Alvarez, Colima, Suchitlan, and in Tecalitalan and Pihuamo, Jalisco, Mexico. foreshocks hit within about 150 km of this epicenter with M 6.1 of September 2, 2022 and M 5.9 on August 13, 2022 but this A national earthquake drill commemorating the M 8.1 on September 19, 1985 occurred about an hour before this earthquake. It is possible that this drill helped save many from death or injury from today's earthquake as they were outdoors and aware of the possibility of a quake at that time. A tsunami warning was issued and later revised. Fluctuation of ocean up to about a foot (0.3 meters) were reported. Gauges in Mexico registered maximum tsunami height of 0.8 m in Manzanillo, 0.5 m in Zihuatanejo and 0.1 in Acapulco. Tsunami waves of 0.12 meters (0.4 feet) were also reported in the Galapagos Islands with similar waves in Lazaro Cardenas, Mexico, Zihuatanejo and Puerto Vallarta, Mexico by PTWC. At least one person was killed when a facade of a department store fell on a man in Manzanillo. A second was killed when falling portions of a Mall hit him. At least 7 were injured but the toll continues to rise as rescue workers begin their work. At least 20 hospitals in Michoacan were damaged. Damage was also reported to hotels, medical facilities, churches and colleges in Coalcoman. More than a million people lost power in the quake. Earthquakes within about 300 km of today's epicenter of M>=7.2 hit this area on April 18, 2014 (M 7.2), January 22, 2004 (M 7.5), January 11, 1997 (M 7.2). The only earthquake of larger magnitude in this area in the past 30 years was an M 8.0 on October 8, 1995. An M 8.1 also occurred in this region of Michoacan exactly 37 years ago – on September 19, 1985. This was widely damaging with more than 35,000 acknowledged deaths especially in the region of Mexico City. It may be the most deadly earthquake recorded in the region of North and Central America since records began. Another deadly earthquake hit this area on September 19, 2017. That event of M 7.1 also caused much damage and deaths in the area." (September 19, 2022)
This epicenter in Jalisco is near the antipode of a tropical storm in the South Indian Ocean. When this storm began this summary noted potential seismic triggering in the Jalisco area of Mexico from antipodal triggering as:
"A tropical cyclone may be forming in the South Indian Ocean east of Madagascar. This system is currently located near 15S 68E and moving to the west at 19 kts with winds up to 33 kts. It could enhance regional seismicity along the ridge lines in the South Indian Ocean area and could affect the antipodal seismicity near the Gulf of California at 15N 112W. Later it could affect seismicity in southern California as it approaches the antipode to that area." (January 10, 2025)
This storm (TC Dikeledi) will be near the antipode to Los Angeles, California around January 18 and could induce enhanced seismicity in that region near that time.
Forecasts 168606 and 168874 had expected strong seismicity in Michoacan, Mexico within about 100 km of today's event was likely around January 9-12, 2025.

Mount Ibu in Halmahera, eastern Indonesia erupted today with hot lava and ash reaching four kilometers into the sky. The eruption occurred at 11:45 UTon January 11, 2025. No new evacuation orders were in effect, but residents have been warned of continuing eruptions. Ibu is located at 1.5N 127.6E. This epicenter is at 103 degrees from the M 7.1 earthquake off northern California of December 5, 2024 a distance which seismic energy is returned to the earth's surface after reflections and refractions off the core-mantle boundary. Seismicity at this distance from major earthquakes often increase in magnitude following mainshocks near distance of 103 degrees.
OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

UNUSUAL EARTHQUAKE IN SOUTHERN AUSTRALIA; MODERATE IN COLOMBIA
EARTHQUAKE SUMMARY FOR JANUARY 10, 2025
New tolls in the M 7.1 earthquake in Tibet, China were released by local officials. These currently stand at 126 killed and 337 injured. It is considered likely that trapped people under rubble are now deceased due to hypothermia of the past three days due to mountain winter temperatures near zero F. More than 47,000 have been evacuated and moved to temporary shelters due to the destruction of their homes in the earthquake. Earthquakes of M 3.9 and 4.0 among many of lesser magnitude hit the area today.
Forecast 168960 had expected continuing aftershocks in the area in mid-January.

An unusual earthquake of M 4.9 shook areas of southern Australia today. NEIC reported it was felt with intensity IV in South Australia at Port Augusta and Port Pirie with intensity II-III in Adelaide, Mount Gambier and Whyalla. The M 4.9 is the strongest earthquake within about 200 km of today's epicenter since an M 4.9 hit about 100 km southeast of this on March 22, 2023. At the time this summary noted:
"An unusual earthquake of M 4.9 occurred today off the southern coast of South Australia. NEIC reported it was felt with intensity IV in South Australia at Port Pirir and II-III in Whyalla, Gawler, Adelaide and Crafers-Bridgewater, Australia. The only earthquake with equal or larger magnitude within about 400 km of this epicenter in the past 35 years was a similar M 4.9 on October 8, 2021 about 400 km to the southeast of today's epicenter. At the time this summary noted:
"An unusual earthquake of M 4.9 occurred in Victoria, Australia today. NEIC reported it was felt with intensity II-III in Victoria and South Australia at Murray Bridge, Horsham, Midua, Moujnt Barker, Victor Harbor, Adelaide, Mount Gambler, Swan Hill, Hamilton and Maryborough. This is the strongest earthquake within about 300 km of this epicenter in at least 30 years. An M 4.8 hit the area on October 27, 2001 and about 400 km northwest of this on May 3, 1997, the only similar quakes in Victoria since 1990." (October 8, 2021)
Today's event in Australia occurred shortly after the Gamma Ray Burst of 21:00 UT and may have been promoted by effects related to this as well as the strong geomagnetic storm and high tidal stresses with the new moon." (March 22, 2023)

Earthquakes of M 2.9 and M 3.6, M 2.5, off central California near San Francisco were felt in the San Francisco area today. Several were widely felt with maximum intensity IV in San Francisco; III in Burlingame, Portola Valley, Sunnyvale, San Mateo, Elk Cerrito, Oakland and II in Brisbane, Daly City, Half Moon Bay, Millbrae, Pacifica, Redwood City, San Bruno, Alameda, Albany, Richmond, among others. EMSC reported these events were felt in San Francisco, San Mateo, Oakland, San Bruno, Pacifica as a short thud. The event of M 3.4-3.6 off shore San Francisco is the strongest recorded within about 50 km of this epicenter since an M 3.7 on October 28, 2023. At the time this summary noted:
"A light M 2.9 in Northern California south of the San Francisco Bay area occurred following the M 5.1 in SE Alaska and may have been triggered by it. The California quake was reported by NEIC to have been felt with intensity II-III in San Jose, Santa Clara, Los Gatos, Mountain View, Boulder Creek, Walnut Creek and San Francisco. This activity occurred during a minor geomagnetic storm in conjunction with the full moon and lunar eclipse today and was probably promoted by stresses associated with those two factors. The last earthquake in San Francisco of similar size was an M 3.6 on December 17, 2022. At the time this summary noted:
"Today's event of M 3.6 is the strongest within the San Francisco Bay area of
California within about 50 km of this epicenter since an M M 4.1 on June 2, 2022 and prior to that an M 3.9 on June 20, 2021 and an M 4.5 on October 15, 2019. At the time of the last such event on June 2, 2022, this summary noted:
"An earthquake of M 4.2 also shook the region of San Francisco, California today. NEIC reported maximum intensity IV in Sulsun City with intensity III throughout most of the rest of the San Francisco Bay area including at Concord, Benicia, Pittsburg, Birds Landing, and Pleasant Hill among others. This is the strongest earthquake in the San Francisco Bay area of California since an M 4.5 on October 15, 2019 and prior to that, events of M 4.2-4.3 on July 16, 2019 and January 4, 2018. The last earthquake of significantly larger magnitude in the San Francisco Bay area was an M 6.0 in the Napa area on August 24, 2014. These are the only events of M>=4.2 in the San Francisco area in the past 13 years." (December 17, 2022, June 2, 2022, October 28, 2023)
Forecast 168644 had expected today's activity in Central California within about
5 km of the epicenter was likely around January 8, 2025.

An earthquake in northern California near Dunnigan occurred two minutes after the M 3.6 in central California, enough time for it to have been triggered by the M 3.6 near San Francisco. This earthquake in northern California was reported by NEIC to have been felt with intensity III in Pacifica and I-II in Livermore, and Rosewood.
An earthquake of M 5.6 also occurred today in Northwestern Colombia. It is likely to have been felt with moderate intensity in Northern Colombia and was reported with light intensity at Buenaventira Valle del Cauca by NEIC.
EMSC reported light to moderate Shaking in Colombia at Medellin and Bogota.
The last earthquake with M>=5.6 within about 200 km of this epicenter in Colombia was recorded as an M 5.7 on August 27, 2023 but the last of significantly larger magnitude in the area was an M 6.7 on August 13, 2013. At the time this summary noted:
"A strong earthquake of M 6.7 hit south of Panama and west of Colombia today. This event was felt widely in Panama and Colombia. NEIC reported intensity IV in Colombia at Circasia, Quindio and Medellin, Antioquia and III in Cali, Evnigado, and Pereira. In Panama it was felt with intensity III in Balboa, Las Tablas, and Panama City and II in Santa Ana Arriba and Veracruz and Ancon. It was generally felt within about 400 km of the epicenter. This is the largest earthquake felt in Colombia in the past six years - since an M 6.8 in September, 2007 which hit the west coast of Colombia. There were no immediate reports of damage or casualties from this event and no tsunami was observed or expected. The city nearest to the epicenter was Mutis, Colombia about 80 km from the epicenter.
The last major earthquake to hit Colombia was an M 6.1 on January 25, 1999,
a quake that killed 1200 people.
This epicenter is at the exact antipode of an M 5.3 which hit south of Sumatra two days ago and may have been promoted or triggered by that event. Frequent readers of this summary know that two epicenters are antipodal if their latitudes are the same and in opposite hemispheres (6N and 6S in the current pair) and their longitudes add to 180 and are in opposite hemispheres (78W and 102E in the current pair). Further activity in Sumatra near this epicenter is likely in the next several days. After this was written an M 4.6 did occur in this region of Sumatra. The earthquake off Panama is the strongest to occur in the world since an M 7.2 in the South Sandwich Islands of July 15, 2013, a month ago. It is also the largest within 200 km of this epicenter to occur since events of M 7.2 on November 15, 2004; October 18, 1992 and November 19, 1991.
The 10- to 11-year cycle here is probably not coincidental but is forced by solar activity also on an 11-year cycle. Forecast 74635 had expected this earthquake was likely in mid-August about 100 km north of today's epicenter with magnitude up to M 6.5. The epicenter off Colombia is located at 144 degrees from the M 6.0 in Xizang, China of two days ago" (August 13, 2013)
Today's Colombia epicenter (like that of the M 6.7 in August, 2013) is at 143 degrees from the M 7.1 in Xizang of January 7, 2025 and is likely an FFA from that source as noted at the time in this summary:

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

NEIC reported earthquakes of M 3.2 and M 3.1 in Hawaii were felt with moderate intensity up to II-III in the area(s) of Hawaii in Honokaa and Kamuela.
January 15, 2025
The strongest earthquake in the world today was an M 5.7 in the Central Mid-Atlantic area. It may have been felt in the epicentral area on board ships.
An earthquake of M 5.0 near Kimbe, New Guinea followed 38 minutes later. This
New Guinea epicenter is near the antipode of the epicenter in the mid-Atlantic.
It occurred as the PPS seismic phase was passing through New Guinea and may
have been promoted by antipodal focused energy from the Mid-Atlantic.
An aftershock of M 5.5 today followed the M 6.8 of January 13, 2025 in Kyushu, Japan. NEIC reported
it was felt with intensity up to III in Miyakonojo, Miyazaki, Japan.
A moderate earthquake occurred off northern Iceland today with M 5.2. It was not
reported in this area near Lauger, Iceland. This is a strongly volcanic region
and earthquakes of M>=5 occasionally occur with volcanism in this region.
The mainshock was followed by at least 300 recorded aftershocks. This
is the strongest earthquake within about 200 km of this epicenter in Iceland
since an M 5.2 on December 8, 2024 and M 5.3 on April 21, 2024. At the time this summary noted:
"The earthquake of M 5.3 in northeastern Iceland is the largest in that area
within about 150 km since a series of moderately large events occurred near this
epicenter in August and September, 2014 - a volcanic series which included
events of M 5.6 and 5.7 on August 26 and 27, 2014. At the time this summary noted:
"The earthquake of M 5.7 in Iceland is the strongest recorded in that area
since an M 5.8 on September 16, 2002, the only other event of this size in
Iceland in the past 25 years. It is part of the sub-glacial Bardarbunga volcanic eruption
in the central portion of that island. ..." (April 21, 2024)
Note that this event, like today's occurred in close temporal proximity to
the full moon. The current full moon occurred about 10 hours after the full
moon of January 13 which had been expected to enhance seismicity
in Iceland as noted in this and previous issues of this summary as:
"The full moon will arrive on January 13, 2025 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/Kermadec Islands, New Zealand to the Balleny Islands and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this full moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this full moon are moderate to high." (January 12-14, 2025)
This epicenter is at the fifth node (72 degrees) from the M 7.1 in Tibet of January 7, 2025
and was probably FFA from that source as noted in this summary at the time:
"Node 5 (72 degrees)
Nepal to Iceland, Andreanof, Rat Islands, Northern Australia, New Guinea, New Britain, Portugal" (January 7, 2025)
Another eruption of Mount Ibu occurred today in Halmahera, Indonesia. This eruption
sent ash and smoke as high as four km into the air. Officials said more
evacuations are likely. On January 12, this summary remarked on the current eruptions of Ibu as:
"Mount Ibu in Halmahera, eastern Indonesia erupted today with hot lava and ash reching four kilometers
into the sky. The eruption occurred at 11:45 UT on January 11, 2025. No new
evacuation orders were in effect, but residents have been warned of continuing
eruptions. Ibu is located at 1.5N 127.6E. This epicenter is at 103 degrees
from the M 7.1 earthquake off northern California of December 5, 2024 a distance
which seismic energy is returned to the earth's surface after reflections and
refractions off the core-mantle boundary. Seismicity at this distance from
major earthquakes often increase in magnitude following mainshocks near
distance of 103 degrees.
An earthquake of M 2.7 occurred today in Virginia. This is the second quake
to strike Virginia in as many days. Today's event was felt with intensity up to IV
throughout much of the eastern seaboard of the U.S. including in Connecticut, Pennsylvania, Virginia, West Virginia, North Carolina, New York, Indiana, Michigan, Missouri, Rhode Island, Alabama, with maximum shaking IV in Glen Allen and Richmond, Virginia, Northfork, West Virginia and Mocksville, North Carolina.
NEIC reported an earthquake of M 3.0 in Hawaii was felt with intensity up to II in the area(s) of Mountain View.
NEIC reported an earthquake of M 2.6 in Southern California was felt with intensity up to II-III in the area(s) of Southern California at Lucerne Valley, Fontana, and Big Bear City.
NEIC reported an earthquake of M 4.0 in Southeastern Alaska was felt with intensity up to III in the area(s) of Southeastern Alaska at Craig, II in Petersburg, Sitka, Klawock and Ketchikan.
NEIC reported an earthquake of M 2.8 in Southern California was felt with intensity up to II in the area(s) of Southern California at Oceanside, San Diego and Imperial.
NEIC reported an earthquake of M 2.7 in New South Wales, Australia was felt with intensity up to III in the area(s) of New South Wales, Australia at Muswellbrook.
The full moon arrived on January 13, 2025 at 22:27 UT. Longitudes which were at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/Kermadec Islands, New Zealand to the Balleny Islands and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this full moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this full moon are moderate to high.

---- ------- ---------- -------- ----- ------ ------- ---------------
TC DIKELEDI 2025-01-15 00:00 UT 21.7S 41.1E 085 kts East of northern Madagascar
Tropical Cyclone Dikeledi (07S) continued today in the area of the south Indian Ocean west of Madagascar with winds up to 85 kts. It is expected to track to the west over the next several days making landfall in northern Madagascar and to dissipate Around January 11, 2025. Some enhanced seismicity in the areas of the Indian Ocean and eastern Africa is possible as this storm makes landfall. This cyclone will reach an area of 34S 62W with winds up to about 100 kts around January 19, 2025. At this time it will be antipodal to Los Angeles, California and could promote enhanced seismicity in that area at that time. Coincidences such as this have been seen in seismicity in Southern California after strong fire events such as is now happening in the area.

January 14, 2025
A strong to major earthquake of M 6.9 hit the area of Kyushu, Japan today. The
quake shook buildings and may have generated a tsunami, but no reports of
major damage or high tsunami waves have been officially made. The largest
tsunami wave was measured at 7.8 inches in Miyazaki City. The quake
was felt in Miyazaki and at least one mine injury was reported by a person who
fell down a flight of stars during the quake. The tsunami warning has now been
lifted but some evacuations may still occur. NEIC reported this earthquake was
felt with intensity IV (Some damage) at Miyazaki, VII in Saiki, Oita; VI in Junitomi, Miyazaki; V in Kanoya, Kagoshima dns Koshi, Kumamoto and with IV in Oita, Osaka, Ehime Fukuoka, Hiroshima, Kagoshima, Shizuoka, South Korea.
This epicenter is at the sixth node (60 degrees) from the M 7.4 in Vanuatu of December 17, 2024
and may have been promoted by energy from that source. It is also at 108 degrees
from Michoacan, Mexico where an M 6.2 occurred earlier in the day. This is in the
zone where core-mantle reflections of seismic waves return to the surface and
appear to help trigger enhanced seismicity at this distance from mainshocks.
The relation to Vanuatu had been noted when that event occurred as:
"Node 6 (60 degrees)
Vanuatu to Honshu, Japan, Kuril Islands, Taiwan, Sumatra, Pacific-Antarctic Ridge, Java, Kyushu, Japan," (December 17, 2024)
The latest tolls from the M 7.1 in Xizang, China of January 7, 2025 indicate that at least 126 were killed and 338 injured in Tibet. At least 47,000 have been relocates as harsh winter conditions make rescue and survival difficult.
Moderate aftershocks of M 5.1 and 5.1 shook the area today. NEIC reported
intensity III shaking in Shiliguri, Bangla, India with II at Rangpo, Sikkim, Indian an II in Nepal at Tribuvannagar, Kathmandu and Dhulikhet.
These earthquakes in Kyushu and China may have been promoted by the new moon of
January 13 as noted in this summary as:
The full moon will arrive on January 13, 2025 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/Kermadec Islands, New Zealand to the Balleny Islands and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this full moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this full moon are moderate to high.
Moderate earthquakes continued today in the region of Ethiopia. These are being
felt in the Awash and Afar Triangle regions of Ethiopia and in Addis Ababa. There
is some concern that they may lead to the eruption of the volcano Mount Dofan and/or
the collapse a a major dam. Many buildings have collapsed and left people homeless. To protect the population evacuations have been
proceeding since December. This has led to mere survival conditions among many of
the evacuated as water and food are in short supply. There is fear of a cholera
epidemic. Magma is spreading through a large fissure about 50 km long and roads
are becoming impassable. Today's events included an M 4.8 felt with intensity III
in Addis Ababa.
News from Xizang China (Tibet) indicates that the recent earthquakes there, starting
with the M 7.1 on January 7, 2025 hav damaged at least two Buddist monasteries and left a number of nuns and monks hurt (Reuters).
Monasteries are a major cultural factor in Tibet. Part of the Dzongbu Temple collapsed and
rescuers pulled several nuns out of the rubble alive. Also affected was the Sengar Chode
Monastery founded in 1541. At least 3,600 homes collapsed
during the earthquakes which left at least 126 people dead. Aftershocks
continued in the region today including two of M 5.1 felt with light intensity
in Kathmandu, Nepal. These earthquakes are located at the fourth node (90 degrees)
from the M 7.4 in Vanuatu of December 17, 2024 and are likely FFA from that event.

The full moon will arrived on January 13, 2025 at 22:27 UT. Longitudes which were at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/Kermadec Islands, New Zealand to the Balleny Islands and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this full moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this full moon are moderate to high.

January 13, 2025
A strong to major earthquake of M 6.9 hit the area of Kyushu, Japan today. The
quake shook buildings and may have generated a tsunami, but no reports of
major damage or high tsunami waves have been officially made. The quake
was felt in Miyazaki and at least one mine injury was reported by a person who
fell down a flight of stars during the quake. The tsunami warning has now been
lifted but some evacuations may still occur. NEIC reported this earthquake was
felt with intensity IV (Some damage) at Miyazaki, VII in Saiki, Oita; VI in Junitomi, Miyazaki; V in Kanoya, Kagoshima dns Koshi, Kumamoto and with IV in Oita, Osaka, Ehime Fukuoka, Hiroshima, Kagoshima, Shizuoka, South Korea.
This epicenter is at the sixth node (60 degrees) from the M 7.4 in Vanuatu of December 17, 2024
and may have been promoted by energy from that source. It is also at 108 degrees
from Michoacan, Mexico where an M 6.2 occurred earlier in the day. This is in the
zone where core-mantle reflections of seismic waves return to the surface and
appear to help trigger enhanced seismicity at this distance from mainshocks.
The relation to Vanuatu had been noted when that event occurred as:
"Node 6 (60 degrees)
Vanuatu to Honshu, Japan, Kuril Islands, Taiwan, Sumatra, Pacific-Antarctic Ridge, Java, Kyushu, Japan," (December 17, 2024)
The latest tolls from the M 7.1 in Xizang, China of January 7, 2025 indicate that at least 126 were killed and 338 injured in Tibet. At least 47,000 have been relocates as harsh winter conditions make rescue and survival difficult.
Moderate aftershocks of M 5.1 and 5.1 shook the area today. NEIC reported
intensity III shaking in Shiliguri, Bangla, India with II at Rangpo, Sikkim, Indian an II in Nepal at Tribuvannagar, Kathmandu and Dhulikhet.
These earthquakes in Kyushu and China may have been promoted by the new moon of
January 13 as noted in this summary as:
The full moon will arrive on January 13, 2025 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/Kermadec Islands, New Zealand to the Balleny Islands and portions of the Pacific-Antarctic Ridge are included.

MODERATELY STRONG QUAKES IN EL SALVADOR AND COLOMBIA
EARTHQUAKE SUMMARY FOR JANUARY 9, 2025
The strongest earthquake in the world today was an M 5.8 aftershock in El Salvador. NEIC reported it was felt with intensity up to V in El Salvador at Concepcion de Ataco, Antiguo Cuscatlan; IV in Nuevo Cuscatlan, Mejiconos, Soyapango, San Salvador, El Salvador and in Guatemala at Palin Escuintla and Guatemala City. Lesser shakin was reported from La Libertad, Guaymanog, Nueva San Salvador, Apopa, Ilopango, Acajutla, and in Gutmala at San Andres Itsapa, Chimaltenango, Petapa. Santa Catarina Pinula, Santa Lucia Milpas, Sacatepequez among others. EMSC reported strong shaking in El Salvador at Colon, Santa Ana, Nueva San Salvador, Xanadu, San Salvador, Mejicanos, and in Guatemala at Guatemala City, Fraijanes, Colonia Valles De Vista Hermosa, and with light shaking at Managua, Nicaragua. This is the strongest aftershock to date of an M 6.2 on January 4, 2025 mainshock.
This summary noted the mainshock M 6.2 in El Salvador of January 4 in that issue of this summary as:
"The strongest earthquake in the world today was an M 6.2 in El Salvador. NEIC reported it was widely felt in El Salvador and surrounding areas with maximum intensity up to VI (Slight damage) in El Salvador at Nuevo Cuscatlan, Ayutuxtepeque, Delgado and V in La Libertad, Nueva San Salvador, San Alejo, Aguilares, Apopa, Ilopango, Mejicanos, San Salvador, Santo Tomas, Soyapango, San Sebastian, among others. It was also felt with intensity III-IV in Guatemala, Honduras, Nicaragua, Puerto Rico. An aftershock of M 4.5 was reported with moderate intensity by EMSC in Nueva San Salvador. EMSC reported strong shaking in El Salvador at Los Planes de Renderos, Soyapango, Mejicanos, Nueva San Salvador, San Salvador, San Miguel, and in Nicaragua at Nagarote, Managua.
The last earthquake in the area of El Salvador with M>=6.2 occurred on July 19, 2023 with M 6.5 and as an M 6.5 on September 22, 2021.
A series of foreshocks hit the region of El Salvador in early January, 2025. The regional stability of El Salvador at this time was discussed in the January 3, 2025 issue of this summary as:
"An earthquake of M 4.0 occurred about 40 minutes after the event in Chile in the area of El Salvador. This is probably a triggered earthquake from Chile. An M 5.6 hit the area on December 9, 2024 several days after the M 7.0 of Northern California of December 5. At the time this summary reported:
"A moderately strong earthquake was widely felt in El Salvador today. NEIC reported this event with M 5.6 was felt with maximum intensity VI in La Union and IV in Anamoros, San Salvador, Santiago de Maria, Choluteca, and in Honduras at Bodega de Los Tangos, Yamaranguila, Marcala,; III in El Salvador at Gotera Morazan, Chirilagua and in Honduras at Choloma, Tegucigalpa, Las Tapias, Valle de Angeles, Yaguacire and La Esperanza among others. This epicenter is located at 40 degrees (360/9) from the earthquake of M 7.0 off northern California of December 5 and was likely a far-field aftershock of that event as previously described in this summary. This earthquake is the strongest in El Salvador since an M 6.5 on July 19, 2023 and a similar M 5.6 on March 17, 2024." (December 9, 2024)
It is worthwhile to note that this epicenter in El Salvador is also at 40 degrees from the M 6.1 in Chile today. Constructive interference at 40 degrees from Northern California and Chile could enhance regional seismicity in El Salvador.
This type of regional seismic triggering is common before larger regional events and El Salvador may see a strong earthquake in the next several days." (January 3, 2025)
Today's events in El Salvador and Colombia are also near 144 degrees from the M 7.1 in Tibet of January 7, 2025 and were probably FFA from that event. This distance is the distance on the earth's surface where core reflections and refractions return to the surface. Seismicity at this distance is commonly seen to be enhanced following major earthquakes at the surface of the earth.
Forecast 168599 had expected today's M 5.8 in El Salvador was likely within
about 50 km around January 9.

P: 9JAN2025 168599 14.0N 90.0W 3.5-5.1 AAAAA Guatemala
An earthquake of M 5.6 also occurred today in Northwestern Colombia. It is likely to have been felt with moderate intensity in Northern Colombia. This epicenter is at 143 degrees from the M 7.1 in Xizang of January 7, 2025 and is likely an FFA from that source as noted at the time in this summary:
"Outer shadow zone edge (141-148 degrees)
Nepal to coast of Mexico, Galapagos, Pacific-Antarctic Ridge, Costa Rica, Ecuador" (January 7, 2025)
The antipode of this epicenter in Colombia is in southern Sumatra, Indonesia at 6S 102-103E. This is an active area and often shows synchronicity in seismicity with stronger events in Colombia. Such an event could occur in the next five days but is not expected to be large.
Forecast 168560 had expected this event was likely within about 200 km of this epicenter in early January.

An unusual series of earthquakes occurred today in the Santa Barbara Channel, California. NEIC reported this earthquake of M 2.9 in Southern California was felt with moderate intensity up to II-III in the area(s) of Southern California in Santa Barbara, Long Beach, Goleta, Ventura. These are in the vicinity of the massive wildfires in the area of Los Angeles over the past several days. These events of M 2.9, 2.3 and 2.3 include the largest event in the area within about 50 km of today's epicenter since an M 3.1 on June 4, 2023. These event occurred near local solar noon and may have been promoted by SFE associated with solar flares and/or tidal stresses both of which maximize at this hour. One of the events - an M 2.3 occurred near the maximum output of solar flare 3760. Data from SWPC for this flare follows.
Hair triggering of this type suggests this may be an area of high stress subject to load associated with the current fires in the area. It is an area where daily inspection of earthquake data may yield insights.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

The strongest earthquake in the world today was an M 6.2 in Jalisco, Western Mexico. NEIC reported it was felt with minor damage at intensity VI levels in Jalisco, Mexico at El Verde and Pihuamo and IV in El Linon, , Tamazula and Teocuitatlan de Corona, Jalisco and in Comala, Colima. Intensity IV was reported from Aguscalientes, Armeria, Colima, Cuauhtemoc, Manzanillo, Suchitlan, Guadalajara, Ixtapa, Las Pintas, Neuvo Mexico, Ocotlan and many others. It was lightly felt as far as Los Angeles, California and in Nayarit, Guerrero and Mexico City, Mexico.
EMSC reported strong shaking in Mexico at Chapala, Barra de Navidad, San Agustin, Guadalajara, Zapopan, Te[atitlan De Morelos, Etzatland, Puerto Vallarta, Azcapotzalco, and Mexico City.
Several moderate aftershocks were also felt in this area of Mexico.
This event occurred near local solar midnight and may have been promoted by
strong tidal stresses which maximize near this hour. This event at M 6.2 is
the strongest in Michoacan, Mexico within about 200 km of this epicenter
since an M 6.8 on September 22, 2022 - an aftershock of an M 7.6 of September
19, 2022 and may be the strongest aftershock to date of those events.
At the time this summary noted:
"NEIC reported the earthquake in Michoacan, Mexico was felt with strong intensity IX in Michoacan at Coshuayana and VUU in Coalcoman. It was also felt with intensity VI in Colima at Colima, Cuauhtemoc, Villa de Alvarez, Colima, Suchitlan, and in Tecalitalan and Pihuamo, Jalisco, Mexico.
foreshocks hit within about 150 km of this epicenter with M 6.1 of September 2, 2022 and M 5.9 on August 13, 2022 but this
A national earthquake drill commemorating the M 8.1 on September 19, 1985 occurred
about an hour before this earthquake. It is possible that this drill helped
save many from death or injury from today's earthquake as they were outdoors
and aware of the possibility of a quake at that time. A tsunami warning was issued and later
revise. Fluctuation of ocean up to about a foot (0.3 meters) were reported. Gauges
in Mexico registered maximum tsunami height of 0.8 m in Manzanillo, 0.5 m in Zihuatanejo and 0.1 in Acapulco. Tsunami waves of 0.12 meters (0.4 feet) were also
reported in the Galapagos Islands with similar waves in Lazaro Cardenas, Mexico, Zihuatanejo and Puerto Vallarta, Mexico by PTWC.
At least one person was killed when a facade of a department store fell on a a man
in Manzanillo. A second was killed when falling portions of a Mall hit him. At least 7 were injured
but the toll continues to rise as rescue workers begin their work. At least 20 hospitals
in Michoacan were damaged. Damage was also reported to hotels, medical facilities, churches and colleges in Coalcoman. More
than a million people lost power in the quake. Earthquakes within about 300 km of today's epicenter of M>=7.2 hit this area
on April 18, 2014 (M 7.2), January 22, 2004 (M 7.5), January 11, 1997 (M 7.2).
The only earthquake of larger magnitude in this area in the past 30 years was an M 8.0
on October 8, 1995. An M 8.1 also occurred in this region of Michoacan exactly 37 years ago - on
September 19, 1985. This was widely damaging with more than 35,000 acknowledged
deaths especially in the region of Mexico City. It may be the most deadly
earthquake recorded in the region of North and Central America since records began. Another
deadly earthquake hit this area on September 19, 2017. That event of M 7.1 also
caused much damage and deaths in the area." (September 19, 2022)

Mount Ibu in Halmahera, eastern Indonesia erupted today with hot lava and ash reching four kilometers
into the sky. The eruption occurred at 11:45 UTon January 11, 2025. No new
evacuation orders were in effect, but residents have been warned of continuing
eruptions. Ibu is located at 1.5N 127.6E. This epicenter is at 103 degrees
from the M 7.1 earthquake off northern California of December 5, 2024 a distance
which seismic energy is returned to the earth's surface after reflections and
refractions off the core-mantle boundary. Seismicity at this distance from
major earthquakes often increase in magnitude following mainshocks near
distance of 103 degrees.

New tolls in the M 7.1 earthquake in Tibet, China were released by local officials.
These currently stand at 126 killed and 337 injured. It is considered likely
that trapped people under rubble are now deceased due to hypothermia of the
past three days due to mountain winter temperatures near zero F. More
than 47,000 have been evacuated and moved to temporary shelters due to the
destruction of their homes in the earthquake.
An unusual earthquake of M 4.9 shook areas of southern Australia today. NEIC reported
it was felt with intensity IV in South Australia at Port Augusta and Port Pirie with intensity II-III in Adelaide, Mount Gambier and Whyalla.
Earthquakes continued in Ethiopia today with the largest of M 5.2 felt in Ethiopia at Addis Ababa with intensity up to IV.
Other events today in this series occurred with M 4.6, 4.5, 4.8,
Earthquakes of M 2.9 and M 3.6, M 2.5, off central California near San Francisco were felt in the San Francisco area today. Several were widely felt with maximum intensity IV in San Francisco; III in Burlingame, Portola Valley, Sunnyvale, San Mateo, Elk Cerrito, Oakland and II in Brisbane, Daly City, Half Moon Bay, Millbrae, Pacifica, Redwood City, San Bruno, Alameda, Albany, Richmond, among others.
EMSC reported these events were felt in San Francisco, San Mateo, Oakland, San Bruno, Pacifica. as a short thud.
An earthquake in northern California near Dunnigan occurred two minutes after
the M 3.6 in central California, enough time for it to have been triggered by
the M 3.6 near San Francisco. This earthquake in northern California was reported
by NEIC to have been felt with intensity III in Pacifica and I-II in Livermore, and Rosewood.
An earthquake of M 5.6 also occurred today in Northwestern Colombia. It is likely
to have been felt with moderate intensity in Northern Colombia and was reported with light intensity at Buenaventira Valle del Cauca by NEIC.
EMSC reported light to moderate Shaking in Colombia at Medellin and Bogota. This epicenter
is at 143 degrees from the M 7.1 in Xizang of January 7, 2025 and is likely
an FFA from that source as noted at the time in this summary:
"Outer shadow zone edge (141-148 degrees)
Nepal to coast of Mexico, Galapagos, Pacific-Antarctic Ridge, Costa Rica, Ecuador" (January 7, 2025)
An unusual series of earthquakes occurred today in the Santa Barbara Channel, California.
These are in the vicinity of the massive wildfires in the area of Los Angeles
over the past several days. These events of M 2.9, 2.3 and 2.3 include
the largest event in the area within about 50 km of today's epicenter since
an M 3.1 on June 4, 2023. These event occurred near local solar noon and
may have been promoted by SFE associated with solar flares and/or tidal stresses
both of which maximize at this hour. One of the events - an M 2.3 occurred near the
maximum output of solar flare 3760. Data from SWPC for this flare follows.
Hair triggering of this type suggests this may be an area of high stress
subject to load associated with the current fires in the area. It is
an area where daily inspection of earthquake data may yield insights.

The strongest earthquake in the world today was an M 5.8 aftershock in El Salvador. NEIC reported it was felt with intensity up to V in El Salvador at Concepcion de Ataco, Antiguo Cuscatlan; IV in Nuevo Cuscatlan, Mejiconos, Soyapango, San Salvador, El Salvador and in Guatemala at Palin Escuintla and Guatemala City. Lesser shakin was reported from La Libertad, Guaymanog, Nueva San Salvador, Apopa, Ilopango, Acajutla, and in Gutmala at San Andres Itsapa, Chimaltenango, Petapa. Santa Catarina Pinula, Santa Lucia Milpas, Sacatepequez among others.
EMSC reported strong shaking in El Salvador at Colon, Santa Ana, Nueva San Salvador, Xanadu, San Salvador, Mejicanos, and in Guatemala at Guatemala City, Fraijanes, Colonia Valles De Vista Hermosa, and with light shaking at Managua, Nicaragua.
This is the strongest aftershock to date of that mainshock. This summary noted the mainshock M 6.2 in El Salvador of January 4 in that issue of this
summary as:
"The strongest earthquake in the world today was an M 6.2 in El Salvador. NEIC reported it was widely felt in El Salvador and surrounding areas with maximum intensity up to VI (Slight damage) in El Salvador at Nuevo Cuscatlan, Ayutuxtepeque, Delgado and V in La Libertad, Nueva San Salvador, San Alejo, Aguilares, Apopa, Ilopango, Mejicanos, San Salvador, Santo Tomas, Soyapango, San Sebastian, among others. It was also felt with intensity III-IV in Guatemala, Honduras, Nicaragua, Puerto Rico.
An aftershock of M 4.5 was reported with moderate intensity by EMSC in Nueva San Salvador.
EMSC reported strong shaking in El Salvador at Los Planes de Renderos, Soyapango, Mejicanos, Nueva San Salvador, San Salvador, San Miguel, and in Nicaragua at Nagarote, Managua.
The last earthquake in the area of El Salvador with M>=6.2 occurred on July 19, 2023 with M 6.5
and as an M 6.5 on September 22, 2021.
A series of foreshocks hit the region of El Salvador in early January, 2025. The
regional stability of El Salvador at this time was discussed in the January 3, 2025
issue of this summary as:
"An earthquake of M 4.0 occurred about 40 minutes after the event in Chile in
the area of El Salvador. This is probably a triggered earthquake from Chile. An M 5.6
hit the area on December 9, 2024 several days after the M 7.0 of Northern California
of December 5. At the time this summary reported:
"A moderately strong earthquake was widely felt in El Salvador today. NEIC reported this event with M 5.6 was felt with maximum intensity VI in La Union and IV in Anamoros, San Salvador, Santiago de Maria, Choluteca, and in Honduras at Bodega de Los Tangos, Yamaranguila, Marcala,; III in El Salvador at Gotera Morazan, Chirilagua and in Honduras at Choloma, Tegucigalpa, Las Tapias, Valle de Angeles, Yaguacire and La Esperanza among others.
This epicenter is located at 40 degrees (360/9) from the earthquake of M 7.0
off northern California of December 5 and was likely a far-field aftershock
of that event as previously described in this summary.
This earthquake is the strongest in El Salvador since an M 6.5 on July 19, 2023
and a similar M 5.6 on March 17, 2024." (December 9, 2024)
It is worthwhile to note that this epicenter in El Salvador is also at 40 degrees
from the M 6.1 in Chile today. Constructive interference at 40 degrees from
Northern California and Chile could enhance regional seismicity in El Salvador.
This type of regional seismic triggering is common before larger regional
events and El Salvador may see a strong earthquake in the next several days." (January 3, 2025)
An earthquake of M 5.6 also occurred today in Northwestern Colombia. It is likely
to have been felt with moderate intensity in Northern Colombia. This epicenter
is at 143 degrees from the M 7.1 in Xizang of January 7, 2025 and is likely
an FFA from that source as noted at the time in this summary:
"Outer shadow zone edge (141-148 degrees)
Nepal to coast of Mexico, Galapagos, Pacific-Antarctic Ridge, Costa Rica, Ecuador" (January 7, 2025)
NEIC reported an earthquake of M 2.6 in California-Nevada was felt with moderate intensity up to II in the area(s) of California-Nevada at Redding, Bella Vista, Shasta Lake and Montgomery Creek.
NEIC reported an earthquake of M 4.7 in Tarapaca, Chile was felt with moderate intensity up to II-III in the area(s) of Tarapaca, Chile at Arica.
GUC provided the following data for this earthquake:
09-01-2025 20:52 18.97 69.45 101 4.8 IV Arica and Parinacota at Codpa, Cuya, San Miguel de AzapaIII in Pocon Chile, Arica; in Tarapaca with intensity II in Alto Hospicio, Iquique, Camina and Huara, Chile.
An unusual series of earthquakes occurred today in the Santa Barbara Channel, California.
These are in the vicinity of the massive wildfires in the area of Los Angeles
over the past several days. These events of M 2.9, 2.3 and 2.3 include
the largest event in the area within about 50 km of today's epicenter since

The strongest earthquake in the world today was an M 5.7 in Southern Qinghai Province, China. NEIC reported it was lightly felt in the epicentral area. This earthquake is near the fourth node (360/4=90 degrees) from both the M 7.0 off Northern California of December 5, 2024 and from the M 7.4 in Vanuatu of December 17, 2024 and may show the continuing effect of node four triggering at this time. An unusual earthquake of M 5.3 in the Drake Passage south of South America is also at 90 degrees from the M 7.4 in Xizang, China today.
The last earthquake in Qinghai, China within about 200 km of today's M 5.7 of equal or larger magnitude occurred on May 21, 2021 with M 7.3 and today's event may be a regional aftershock of that although it occurred about 100 km southeast of that epicenter. At the time this summary noted:
"The strongest earthquake in the world today was an M 7.3-7.4 in southern Qinghai, China. NEIC reported maximum intensity VII in Qinghai, China at Xining with II-III shaking in China at Lanzhou, Gansu, Chengdu, Sichean, Kian, Shaanxi, Anshun, Guizhou, Changsham Hunan and in India at Pasighat Arunachal Pradesh and Dhlia Gaon, Assam. It was followed by a series of moderate aftershocks. The M 7.3 followed an M 6.2 in Yunnan, China earlier in the day. Chinese media reported at least three people were kill and 33 injured. The event in Yunnan occurred near the city of Dali, a popular tourist destination according to CENC (Chinese Earthquake Networks Centre). All of the deaths occurred with the Yunnan quake as well as 28 of the 33 reported injuries. At least 192 building collapsed in this earthquake. Two bridges also collapsed and several sections of highways were destroyed. The larger quake in Qinghai was less damaging as it occurred in a sparsely populated area. At least 20,000 people were relocated following today's earthquakes in China." (May 21, 2021)
Forecast 168682 had expected enhanced seismicity within about 200 km of today's
Qinghai event was likely around January 4, 2025.

The strongest earthquake in the U.S. or Canada today was an M 4.2 in western Texas. NEIC reported it was felt with maximum intensity IV in Roswell, New Mexico; III in Carlsbad and in Texas at Fort Davis, Pecos and Salt Flat and II in Texas at Fort Stockton, Alpine, El Paso among others. The last earthquake of M>=4.2 in the region of western Texas was an M 4.2 on November 2, 2024. Only one earthquake of M>4.2 has hit this region in the past year - an M 5.1 on September 17, 2024.

The last earthquake of M>=4.2 in western Texas within about 150 km of today's epicenter occurred on July 23, 2024 with M 4.2. At the time this summary noted:
"The strongest and most unusual earthquake in the U.S. or Canada today was an M 4.9 in Central Texas. NEIC reported it was felt with intensity up to M 4.9 in Hermleigh, Texas and later by an M 4.4 north of Hermleigh. EMSC reported a hard shake in Texas was felt in Sweetwater, Snyder, Midland, Weatherford, Willow Park, Denton, Frisco. It was preceded by an M 4.2 in western Texas west of this epicenter (probably triggering the larger, later event. NEIC reported it was felt with intensity up to V in the epicentral area near Whites City, New Mexico." (July 23, 2024, November 2, 2024))

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

OTHER CALIFORNIA WILD FIRES COULD PRECEDE ENHANCED SEISMICITY
EARTHQUAKE SUMMARY FOR JANUARY 7, 2025
A major series of wildfires is currently consuming large portions of acreage in
Southern California in the Los Angeles region. The cause of these is currently being investigated but is not known a this writing. Thousands of homes have been burnt to the ground, millions are without electricity and injuries and deaths have not been calculated at this point. This is a major disaster for the area. Fire fighters and disaster personel are on the scene trying to mitigate the disaster and winds are expected to be at lower speeds in the next day. While this is not an earthquake, or earthquake related, the residents of this heavily populated area of the U.S. southwest are in our thoughts.
In terms of earthquakes there have been two major earthquake disasters in the Los Angeles area in the past 90 years. The first of these occurred as the San Fernando earthquake of M 6.8 of February 9, 1971. This was described in this summary as:
"2 9 14 0 55 1971 34.400 -118.434 9 6.7 So. California
The San Fernando earthquake. Maximum intensity VI when the Olive View Hospital was destroyed. 58 killed of which 49 were at the San Fernando Veterans Ad. Hospital. More than 2,000 injured. Damage estimated at more than $500 million. The near-failure of the Lower Van Norman Dam caused evacuation of thousands. Electrical and utilities were completely disrupted. Ground faulting was observed in the San Fernando area and landslides were common. Highway overpasses, railroads, pipelines were severely damaged by slides. Roads were blocked by rockfalls." (February 9, 2024)
The other was the Northridge earthquake of January 17, 1994 of M 7.0 as described in this summary:

Strongly damaging in the Los Angeles, Ventura, Orange and San Bernardino area with maximum damage in the Northridge area. Up to 60 killed and 7000 injured. 40,000 buildings damaged and more than 20,000 homeless. Maximum intensity was IX at Northridge and Sherman Oaks. Overpasses on the Santa Monica Freeway collapsed. Damage also to other freeways in the area. Fires were started by the earthquakes which caused additional damage. Estimated damage was $20 billion (U.S. Dollars). Felt throughout southern California into Nevada, Utah and Baja, California. Rockslides closed many roads. Ground cracks were noted at Granada Hills and Potrero Canyon. Liquefaction occurred in the Los Angeles Basin." (January 17, 2024)
The Northridge earthquake was preceded by a series of disastrous fires in the area described in the UNDRR (United Nations report as:
"USA: The 1993 Southern California Fires (IFFN No 10- January 1994)
Southern California suffered another disastrous series of Fires in October and November 1993. The fires started on 26 October under sever Santa Ana Wind conditions, some by arson and other accidentally. Preliminary data indicate that a total of 21 fires covered 197225 acres (almost 84,000 ha) injuring 162 people and killing three. The fires destroyed 1241 structures and damage was preliminarily estimated by be $500 million, although that figure could rise as damage is further assessed and the aftermath of heavy rains, mudslides, and floods after the fires takes its toll.
The fires were in six southern California counties - Los Angeles, Orange, Riverside, San Bernardino, San Diego and Ventura."
Likewise the San Fernando earthquake of 1971 had been preceded several months before by a major wild fire in the Los Angeles area. The website htts://achistory.com/gif/galleries/fire092570/ describes this fire as:
"September 25, 1970 - The Clampitt (Newhall and W4ight (Malibu) fires of September 25, 1970 merged to become the largest and deadliest wildfire in modern Los Angeles County history, up to that point.
The Clampitt fire broke out around 8 a.m. Friday, Sept. 25, near Clampitt Road in the Newhall Pass as a result of Downed power lines. In Santa Ana winds clocked at 80 mph, it took less than a day for the fire to make a 20-mile run to the coast, tearing through Porter Ranch, the Simi Hills at Chatsworth, south to the 101 Freeway and on to Malibu Canyon. News reports initially called it the Chatsworth-Malibu Canyon fire because much of the destruction occurred there.
By the time the smoke cleared, the Clampitt Fire had scorched 107,103 acres of brush and forest, destroyed 80 structures (source: University of California Division of Agriculture and Natural Resources). It sill stands as L.A. County's deadliest wildfire in modern history ..."
While other wildfires of lesser extent occur in the area of Los Angeles every year. The seasonal Santa Ana winds are a major factor in spreading the fires. But is there a relation between major wild fires in the Los Angeles area and subsequent earthquakes such as those of February, 1971 and January, 1994?
This summary has previously noted that there may be such a connection. Fires remove a substantial mass from the surface over a broad area. This mass is redistributed through winds and carried away by human activities out of the region. As with, but reverse from, reservoir loading and subsequent earthquakes, this can lead to substantial adjustment in the stress environment of the area beneath the fires and perhaps to strong earthquakes.
Significant earthquakes in the area of Los Angeles often occur when a tropical cyclone is active in the South Indian Ocean east and south of Madagascar (at the antipode of Los Angeles - 34S 62E). So readers may want to watch for such a meteorological storm in the next couple of months.
At the very least, these fires remind that the first several months of the year (January-March) are the most likely to see major earthquakes in the area of southern California near Los Angeles and since it has been 31 years since the last such event, one might be overdue. Keeping a well stocked emergency kit for local or regional disasters is especially important. And keeping valuables and transportation easily in reach is also recommended. This summary will attempt to provide warnings if such an event seems imminent.
A moderately strong earthquake occurred today as an M 5.6 in the Izu Islands, Japan. NEIC reported it was felt with intensity II-III in Japan with III in Tokyo, Oamishirasato, Chiba, and II in Saku, Nagano and in Kanagawa at Zushi, Kamakura and Hadano. The last earthquake within about 200 km of this event in the Izu Island occurred on July 23, 2024 also with M 5.6. The last in the area of larger magnitude was an M 6.1 on October 6, 2023. At the time this summary noted:
A strong earthquake also occurred today as an M 6.1 in the Izu Islands off southeastern Honshu, Japan. NEIC reported it was felt lightly in Chiba, Japan.
It was accompanied by a series of moderate foreshocks and aftershocks. This continues the current swarm of events in the Izu Islands which was addressed in the previous summary as:
"The largest earthquake in the world today was an M 6.1 in the Izu Islands, Japan. It was reported by NEIC to have been felt with light intensity in Saitama, Japan. It was accompanied by moderately large quakes of M 5.8, 4.2, 5.5, 5.6 and 5.6. This follows a long run-up to this swarm over the past week. This was noted in the previous issue of this summary as:
"Moderate earthquakes also continued today in the Bonin and Izu Islands of Japan today. The largest of these today were M 5.0-5.1. These events had been noted in previous issues of this summary as:
"The earthquake of M 5.7 in the Izu Islands, Japan was followed by an M 4.7 three hours later. This follows a series of such events in the area including an M 5.8 on September 19. At the time this summary noted:
"An M 5.8 also occurred in the Izu Islands south of southeastern Honshu, Japan today. A similar M 5.8 occurred on February 5, 2023 and an M 6.3 in the Izu Islands was recorded on January 16, 2023...." (October 4-6, 2023)
Forecast 168648 had expected the Izu Islands would be active within about
200 km of this epicenter around January 8, 2025.

An earthquake of M 5.2 in the mid-Indian Ridge was followed by an M 4.9 aftershock. These remote events were not reported felt. They are at 106 degrees from the M 6.8 in the Kuril Islands of December 28, 2024 and may have been promoted by energy from that source near the edge of the core-mantle shadow zone boundary. The antipode of this event is near 38N 102W in western Kansas and Nebraska. A small FFA is possible, but unlikely, in that area. Forecast 168812 had expected this activity within about 100 km was likely around January 4.

NEIC reported earthquakes of M 5.3, 4.7, 4.9 in Ethiopia were felt with moderate intensity up to II-III in the area(s) of Ethiopia at Addis Ababa, and in Oromia, Ethiopia at Debre Zeyit and Asbe Teferi. This seismicity in Ethiopia resumed early on January 8 with an M 5.3. The area experienced a brief lull following the M 7.1 in Xizang, China. An M 4.9 was recorded within minutes of both that quake and local solar noon on January 7 and was probably promoted by strong tidal stresses which maximize near this hour. These earthquakes in Ethiopia and Izu Islands are near the eighth node (360/8=45 degrees) from the M 7.1 in Xizang and may have been promoted by energy from that source.
Forecast 168598 had expected continued moderate aftershocks in Ethiopia were likely around January 7, 2025.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

No Tropical Cyclones are currently active
A tropical cyclone may be forming in the South Indian Ocean east of Madagascar. This system is currently located near 15S 68E and moving to the west at 19 kts with winds up to 33 kts. It could enhance regional seismicity along the ridge lines in the South Indian Ocean area and could affect the antipodal seismicity near the Gulf of California at 15N 112W. Later it could affect seismicity in southern California as it approaches the antipode to that area.

January 8, 2025
A major series of wildfires is currently consuming large portions of acerage in
Southern California in the Los Angeles region. The cause of these is currently
being investigated but is not known a this writing. Thousands of homes have
been burnt to the ground, millions are without electricity and injuries and deaths
have not been calculated at this point. This is a major disaster for the area.
Fire fighters and disaster personel are on the scene trying to mitigate the
disaster and winds are expected to be at lower speeds in the next day.
While this is not an earthquake, or earthquake related, the residents of this heavily populated area of the U.S. southwest are in
our thoughts.
In terms of earthquakes there have been two major earthquake disasters in
the Los Angeles area in the past 90 years. The first of these occurred as the
San Fernando earthquake of M 6.8 of February 9, 1971. This was described in
this summary as:
"2 9 14 0 55 1971 34.400 -118.434 9 6.7 So. California
The San Fernando earthquake. Maximum intensity VI when the Olive View Hospital was destroyed. 58 killed of which 49 were at the San Fernando Veterans Ad. Hospital. More than 2,000 injured. Damage estimated at more than $500 millioin. The near-failure of the Lower Van Norman Dam caused evacuation of thousands. Electrical and utilities were completely disrupted. Ground faulting was observed in the San Fernando area and landslides were common. Highway overpasses, railroads, pipelines were severely damaged by slides. Roads were blocked by rockfalls." (February 9, 2024)
The other was the Northridge earthquake of January 17, 1994 of M 7.0 as described
in this summary:
" 1 17 12 30 55 1994 34.220 -118.760 18 7.0 So. California
Strongly damaging in the Los Angeles, Ventura, Orange and San Bernardino area with maximum damage in the Northridge area. Up to 60 killed and 7000 injured. 40,000 buildings damaged and more than 20,000 homeless. Maximum intensity was IX at Northridge and Sherman Oaks. Overpasses on the Santa Monica Freeway collapsed. Damage also to other freeways in the area. Fires were started by the earthquakes which caused additional damage. Estimated damage was $20 billion (U.S. Dollars). Felt throughout southern California into Nevada, Utah and Baja, California. Rockslides closed many roads. Ground cracks were noted at Granada Hills and Potrero Canyon. Liquefaction occurred in the Los Angeles Basin." (January 17, 2024)
The Northridge earthquake was preceded by a series of disastrous fires in the
area described in the UNDRR (United Nations report as:
"USA: The 1993 Southern California Fires (IFFN No 10- January 1994)
Souothern California suffered another disastrous series of Fires in October and November 1993. The fires
started on 26 October under sever Santa Ana Wind conditions, some by arson and other accidentally. Preliminary data indicat that a total of 21 fires covered 197225 acres (almost 84,000 ha) injuring 162
people and killing three. The fires destroyed 1241 structures and damage was preliminarily estimated by be $500 million, although
that figure could rise as damage is further assessed and the aftermath of heavy rains, mudslides, and floods afer the fires takes its toll.
The fires were in six southern California counties - Los Angeles, Orange, Riverside, San Bernardino, San Diego and Ventura."
Likewise the San Fernando earthquake of 1971 had been preceded several months
before by a major wild fire in the Los Angeles area. The website htts://achistory.com/gif/galleries/fire092570/
describes this fire as:
"September 25, 1970 - The Clampitt (Newhall and W4ight (Malibu) fires of September 25, 1970 merged to become the
largest and deadliest wildfire in modern Los Angeles County histor, up to at point.
The Clampitt fire broke out around 8 a.m. Friday, Sept. 25, near Clampitt Road in the Newhall Pass as a result of
Downed power lines. In Santa Ana winds clocked at 80 mph, it took less than a daa for the fire to make a 20-mile run to the coast, tearing through Porter Ranch, the Simi Hills at Chatsworth, south to the 101 Freeway and on to Malibu Canyon. News reports initially called
it the Chatsworth-Maliby Canyon fire because much of the destruction occurred there.
By the time the smoke cleared, the Clampitt Fire had scorched 107,103 acres
of brush and forest, destroyed 80 structures (source: University of California Division of Agriculture and Natural Resources). It sill stands as L.A. County's deadliest wildfire in modern history ..."
While other wildfire of lesser extent occur in the Los Angeles every year. The
seasonal Santa Ana winds are a major factor in spreading the fires. But is there
a relation between major wild fires in the Los Angeles area and subsequent
earthquakes such as those of February, 1971 and January, 1994?
This summary has previously noted that there may be such a connection. Fires
remove a substantial mass from the surface over a broad area. This mass is redistributed
through winds out of the region. As with, but reverse from, reservoir loading
and subsequent earthquakes, this can lead to substantial adjustment in the
stress environment of the area beneath the fires and perhaps to strong
earthquakes.
Significant earthquakes in the area of Los Angeles often occur when a tropical
cyclone is active in the South Indian Ocean east and south of Madagascar (at
the antipode of Los Angeles). So readers may want to watch for such a meteorological
storm in the next couple of months.
At the very least, these fires remind that the first several months of the
year (January-March) are the most likely to see major earthquakes in the
area of southern California near Los Angeles and since it has been 31 years
since the last such event, one might be overdue. Keeping a well stocked
emergency kit for local or regional disasters is especially important. And
keeping valuables and transportation easily in reach is also recommended.
This summary will provide warnings if such an event seems imminent.
The strongest earthquake in the world today was an M 5.6 in the Izu Islands, Japan. NEIC reported it was felt with intensity II-III in Japan with III in Tokyo, Oamishirasato, Chiba, and II in Saku, Nagano and in Kanagawa at Zushi, Kamakura and Hadano.

MAJOR QUAKE DAMAGING; DEADLY IN NEPAL AND XIZANG, CHINA
EARTHQUAKE SUMMARY FOR JANUARY 6, 2025
A major earthquake of M 6.8-7.1 occurred in Nepal and Xizang, China (Tibet) today. It was felt widely from Xizang, China to Nepal to India. NEIC reported maximum intensity VI in Bangla and Bihar, India at Islampur and Munger and V at Baharampur, Kalimpong, Dinapur, Koilwar, Motihari, Raxaul, Samastipur, in Nepal with intensity V in Bhimeshwar, Mechinagar, Banepa, Butwal; with IV in Bangladesh at Sherpur, Nawabganj, Narayanganj, Rangpur, Rajshahi; in Bhutan at Phuentsholing, among others. EMSC reported strong shaking in Nepal at Kathmandu, Malangwa, and in India at Majorganj, Jaygaon, Nyoti Nagar, Bairatisal, West Ashrampara, Arbinda Pally, Jalpaiguri, Paljor Stadium area, Namchi, Sikkim, India, Darjeeling, Kalimpong, Siliguri, among others. Initial reports indicate that more than 95 people were killed in the earthquake with at least 130 injured. AP reported major damage of the Tibetan holy city of Shigatse. At least 1000 homes were damaged. The epicenter is about 75 km from Mount Everest, the tallest mountain in the world. Operations at that location have ceased for the immediate threats of aftershocks or landslides related to today's event. Minor damage was initially reported confined to areas of southern Xizang, China and Nepal. Videos on the internet show some damage in these areas. The mainshock was followed by a series of moderate aftershocks which NEIC reported were felt with moderate to strong intensity (V) in Kathmandu, Nepal.
A light M 3.9 foreshock hit this area of Nepal on January 3, 2025 and was noted in this summary at the time as:
"EMSC reported an earthquake of M 3.9 in Nepal was felt with intensity up to IV in the area(s) of Nepal at Kathmandu." (January 3, 2025)
These epicenters are at the fourth node (90 degrees) from the M 7.4 in Vanuatu of December 17, 2024 and were in an area where enhanced seismicity after that quake was expected in this summary on December 17 as:
"Node 4 (90 degrees)
Vanuatu to Washington State, Gulf of California, Central China, Revillo Gigedo Island, Mexico, Jalisco, Mexico, Nevada, Nepal, Arizona, Oregon, Northern, Central East Pacific Rise, Nepal, Utah, Gulf of California, " (December 17, 2024)
It is also at 104-105 degrees from the M 7.0 off Northern California of December 5, 2024 – likewise in an area where enhanced seismicity had been expected following that event as noted at the time in this summary:
"Inner shadow zone edge (101-110 degrees)
Coast of Northern California to Celebes, Turkmenistan, Assam, India, China, Iran, Mid-Atlantic, New Zealand, Myanmar, Ceram, Halhahera, Molucca, Cyprus, Crete, Greece, Ceram, Christchurch, New Zealand, Molucca, Afghanistan, Caucasus, Irian Jaya, Mindanao, ", (December 5, 2024)
The last earthquake of M>=6.5 within about 300 km of today's epicenter occurred as an M 7.3 on May 12, 2015 - a regional aftershock of an M 7.8 of April 25, 2015. At the time this summary noted:
"The strong earthquake of M 7.2 in Nepal was widely felt in the region. This report noted in the previous issue in regard to the possibility of a strong aftershock in Nepal at this time:
"The great earthquake in Nepal of April 25 occurred half a lunar month ago.
In many areas tidal forces are maximized at 14-15 day intervals and can help trigger large aftershocks at that time. A strong aftershock in Nepal is overdue after a series of quiet days in that region. There were some moderate events in the area today leading to speculation that a larger earthquake may be imminent. The death toll from the mainshock is over 8000 now and many buildings are damaged and could collapse in a major aftershock. As the migration of major earthquakes at the fifth node from Nepal (72 degrees) in the New Britain area has been moving to the east as noted in previous issues of this report, a strong aftershock in Nepal would also likely be 100-200 km east of the April 25 mainshock." (April 11-12, 2015)
The earthquake in Nepal of M 7.2 brought fresh death and destruction to that country. Initial deaths are listed at 65 in Nepal and 17 more in India with the latest event and more than 8000 from the mainshock. In addition more than 2000 more were injured in today's aftershock and scores of buildings collapsed after being weakened in the mainshock. Most of the casualties were listed in Dolakha district north of Kathmandu. The quake was centered near Mt. Everest and was followed by at least 17 moderate aftershocks including an M 6.2. Landslides caused additional destruction. At least one aid helicopter was missing and presumed down. Flights to Kathmandu were diverted for most of the day. Schools remained closed probably for another two weeks. The quake was felt throughout Nepal, in Pakistan, Bihar, northern India and China where at least one person was killed in Tibel. The quake occurred shortly after local solar noon and was probably promoted by tidal stresses as was the mainshock two weeks ago (occurred minutes before local solar noon). Today's aftershock is about 150 km to the east of the mainshock of April 25 and affected a slightly different population." (May 12, 2015)
The last earthquake to hit within about 150 km of today's epicenter with M>=6.5 occurred as an M 6.9 on September 18, 2011. Far-field aftershocks following today's M 7.1 may be expected in the following general regions in the coming days:

A moderately strong earthquake occurred today in the Izu Islands, Japan. NEIC reported it was felt with intensity II-III in Japan at Tokyo and Saku, Nagano.
EMSC reported it was felt with slow tremor in Japan at Bunkyo and Hanamigawa.
A moderate earthquake shook Greece today with M 4.7. NEIC reported it was felt with intensity V in Zakharo, Ilia, Greece. EMSC reported it was strongly felt in Greece at Tholo, Kyparissia, Spiantza, Pyrgos, Chora, Pylos, Messini, Kouroyta, Kalamata, Agios Andreas, Kaminia, Patras, Loutraki, Pireus, Ionnina among others. This event occurred near local solar noon and may have been promoted by SFE which maximize effects near local solar noon from a C6.6 solar flare which was simultaneous with this earthquake as seen from data from SWPC which follow:
SOLAR FLARES
Flare # START MAX END CLASS DATE Flux (Jm-2)

A minor foreshock of M 2.7 hit the region of southern Greece with the previous flare (3190) perhaps indicating a weakness to SFE at this time.
A series of minor foreshocks hit this same area of Greece as reported in the previous issue of this summary with a moderate solar flare.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

No earthquakes of M>=3 were located in Hawaii.
January 7, 2025
A major earthquake of M 7.0 occurred in Nepal and Xizang, China (Tibet) today. It was felt widely from Xizang, China to Nepal to India. NEIC reported maximum intensity VI in Bangla and Bihar, India at Islampur and Munger and V at Baharampur, Kalimpong, Dinapur, Koilwar, Motihari, Raxaul, Samastipur, in Nepal with intensity V in Bhimeshwar, Mechinagar, Banepa, Butwal; with IV in Bangladesh at Sherpur, Nawabganj, Narayanganj, Rangpur, Rajshahi; in Bhutan at Phuentsholing, among others.
EMSC reported strong shaking in Nepal at Kathmandu, Malangwa, and in India at Majorganj, Jaygaon, Nyoti Nagar, Bairatisal, West Ashrampara, Arbinda Pally, Jalpaiguri, Paljor Stadium area, Namchi, Sikkim, India, Darjeeling, Kalimpong, Siliguri, among others.
Initial reports indicate that more than 95 people were killed in the earthquake with at least 130 injured. AP reported major damage of the Tibetan holy city of Shigatse.
At least 1000 homes were damaged. The epicenter is about 75 km from Mount Everest,
the tallest mountain in the world. Operations at that location have ceased for the
immediate threats of aftershocks or landslides related to today's event. Minor damage was initially reported confined to areas of southern Xizang, China and Nepal.
Videos on the internet show some damage in these areas. The mainshock was followed by a series of moderate aftershocks which NEIC reported
were felt with moderate to strong intensity (V) in Kathmandu, Nepal.
A light M 3.9 foreshock hit this area of Nepal on January 3, 2025 and was noted in this summary at the time as:
"EMSC reported an earthquake of M 3.9 in Nepal was felt with intensity up to IV in the area(s) of Nepal at Kathmandu." (January 3, 2025)
These epicenters are at the fourth node (90 degrees) from the M 7.4 in Vanuatu of December 17, 2024
and were in an area where enhanced seismicity after that quake was expected
in this summary on December 17 as:
"Node 4 (90 degrees)
Vanuatu to Washington State, Gulf of California, Central China, Revillo Gigedo Island, Mexico, Jalisco, Mexico, Nevada, Nepal, Arizona, Oregon, Northern, Central East Pacific Rise, Nepal, Utah, Gulf of California, " (December 17, 2024)
It is also at 104-105 degrees from the M 7.0 off Northern California of December 5, 2024 - likewise
in an area where enhanced seismicity had been expected following that event
as noted at the time in this summary:
"Inner shadow zone edge (101-110 degrees)
Coast of Northern California to Celebes, Turkmenistan, Assam, India, China, Iran, Mid-Atlantic, New Zealand, Myanmar, Ceram, Halhahera, Molucca, Cyprus, Crete, Greece, Ceram, Christchurch, New Zealand, Molucca, Afghanistan, Caucasus, Irian Jaya, Mindanao, ", (December 5, 2024)
The last earthquake of M>=6.5 within about 300 km of today's epicenter occurred
as an M 7.3 on May 12, 2015 - a regional aftershock of an M 7.8 of April 25, 2015.
At the time this summary noted:
"The strong earthquake of M 7.2 in Nepal was widely felt in the region. This
report noted in the previous issue in regard to the possibility of a strong
aftershock in Nepal at this time:
"The great earthquake in Nepal of April 25 occurred half a lunar month ago.
In many areas tidal forces are maximized at 14-15 day intervals and can
help trigger large aftershocks at that time. A strong aftershock in Nepal
is overdue after a series of quiet days in that region. There were some
moderate events in the area today leading to speculation that a larger earthquake
may be imminent. The death toll from the mainshock is over 8000 now and
many buildings are damaged and could collapse in a major aftershock.
As the migration of major earthquakes at the fifth node from Nepal (72 degrees)
in the New Britain area has been moving to the east as noted in previous issues of this report,
a strong aftershock in Nepal would also likely be 100-200 km east of the
April 25 mainshock." (April 11-12, 2015)
The earthquake in Nepal of M 7.2 brought fresh death and destruction to that
country. Initial deaths are listed at 65 in Nepal and 17 more in India with the latest event and more than
8000 from the mainshock. In addition more than 2000 more were injured in
today's aftershock and scores of buildings collapsed after being weakened
in the mainshock. Most of the casualties were listed in Dolakha district north of
Kathmandu. The quake was centered near Mt. Everest and was followed by at
least 17 moderate aftershocks including an M 6.2. Landslides caused additional
destruction. At least one aid helicopter was missing and presumed down. Flights
to Kathmandu were diverted for most of the day. Schools remained closed probably
for another two weeks. The quake was felt throughout Nepal, in Pakistan, Bihar,
northern India and China where at least one person was killed in Tibel.
The quake occurred shortly after local solar noon and was probably promoted
by tidal stresses as was the mainshock two weeks ago (occurred minutes before
local solar noon). Today's aftershock is about 150 km to the east of the
mainshock of April 25 and affected a slightly different population." (May 12, 2015)
The last earthquake to hit within about 150 km of today's epicenter with M>=6.5
occurred as an M 6.9 on September 18, 2011.
Far-field aftershocks following today's M 7.1 may be expected in the following
general regions in the coming days:
Outer shadow zone edge (141-148 degrees)
Nepal to coast of Mexico, Galapagos, Pacific-Antarctic Ridge, Costa Rica, Ecuador
Node 3 (120 degrees)
Nepal to northern Baja California, Mexico, western Texas, Alabama, Mississippi, New Mexico, Baja, northern Gulf of California,
P- and S- shadow zone edge and node 7 (101-110 degrees)

Nepal to Ukraine, Kuril Islands, Quebec, Bonin Islands, Crete, Greece, Mariana Is., Izu Islands, Japan, Timor, Mariana Islands,
Node 8 (45 degrees)
Nepal to Mindanao, Ceram,
An M 5.2 was also felt north of today's M 7.1 event in the region of western Xizang. NEIC reported light shaking from this event in the area of Gangtok, Sikkim, India.
This epicenter (like the M 7.1 later in the day) is at about 102 degrees from the M 7.0 in Northern California
and at the fourth node from Vanuatu.
A moderately strong earthquake occurred today in the Izu Islands, Japan. NEIC reported it was felt with intensity II-III in Japan at Tokyo and Saku, Nagano.
EMSC reported it was felt with slow tremor in Japan at Bunkyo and Hanamigawa.
A moderate earthquake shook Greece today with M 4.7. NEIC reported it was felt with intensity V in Zakharo, Ilia, Greece. EMSC reported it was strongly felt in Greece at Tholo, Kyparissia, Spiantza, Pyrgos, Chora, Pylos, Messini, Kouroyta, Kalamata, Agios Andreas, Kaminia, Patras, Loutraki, Pireus, Ionnina among others.
This event occurred near local solar noon and may have been promoted by SFE which maximize effects near local solar noon from a C6.6 solar flare which
was simultaneous with this earthquake as seen from data from SWPC which follow:

STRONG QUAKE SHAKES EL SALVADOR AND GUATEMALA AREA
EARTHQUAKE SUMMARY FOR JANUARY 5, 2025
The strongest earthquake in the world today was an M 6.2-6.3 in El Salvador. NEIC reported it was widely felt in El Salvador and surrounding areas with maximum intensity up to VI (Slight damage) in El Salvador at Nuevo Cuscatlan, Ayutuxtepeque, Delgado and V in La Libertad, Nueva San Salvador, San Alejo, Aguilares, Apopa, Ilopango, Mejicanos, San Salvador, Santo Tomas, Soyapango, San Sebastian, among others. It was also felt with intensity III-IV in Guatemala, Honduras, Nicaragua, Puerto Rico. The mainshock was followed by a series of lightly felt aftershocks up to M 4.5 An aftershock of M 4.5 was reported with moderate intensity by EMSC in Nueva San Salvador. EMSC reported strong shaking in El Salvador at Los Planes de Renderos, Soyapango, Mejicanos, Nueva San Salvador, San Salvador, San Miguel, and in Nicaragua at Nagarote, Managua.
The last earthquake in the area of El Salvador with M>=6.2 occurred on July 19, 2023 with M 6.5 and as an M 6.5 on September 22, 2021.
A series of foreshocks hit the region of El Salvador in early January, 2025. The regional stability of El Salvador at this time was discussed in the January 3, 2025 issue of this summary as:
"An earthquake of M 4.0 occurred about 40 minutes after the event in Chile in the area of El Salvador. This is probably a triggered earthquake from Chile. An M 5.6 hit the area on December 9, 2024 several days after the M 7.0 of Northern California of December 5. At the time this summary reported:
"A moderately strong earthquake was widely felt in El Salvador today. NEIC reported this event with M 5.6 was felt with maximum intensity VI in La Union and IV in Anamoros, San Salvador, Santiago de Maria, Choluteca, and in Honduras at Bodega de Los Tangos, Yamaranguila, Marcala,; III in El Salvador at Gotera Morazan, Chirilagua and in Honduras at Choloma, Tegucigalpa, Las Tapias, Valle de Angeles, Yaguacire and La Esperanza among others. This epicenter is located at 40 degrees (360/9) from the earthquake of M 7.0 off northern California of December 5 and was likely a far-field aftershock of that event as previously described in this summary. This earthquake is the strongest in El Salvador since an M 6.5 on July 19, 2023 and a similar M 5.6 on March 17, 2024." (December 9, 2024)
It is worthwhile to note that this epicenter in El Salvador is also at 40 degrees from the M 6.1 in Chile today. Constructive interference at 40 degrees from Northern California and Chile could enhance regional seismicity in El Salvador.
This type of regional seismic triggering is common before larger regional events and El Salvador may see a strong earthquake in the next several days. Today's event in El Salvador is also at 106 degrees (core-mantle shadow zone boundary where p- and s- phases converge at the earth’s surface) from the M 7.4 in Vanuatu of December 17, 2024. It had been expected as a far-field aftershock of that earthquake at the time as:
"Inner shadow zone edge (101-110 degrees)
Vanuatu to Peru, Western Texas, Missouri, Kyrgyzstan, Scotia Sea, Central Chile, Arctic Ocean, Pakistan, Xinjiang, China, Oaxaca, Chiapas, Mexico, Guatemala, Tajikistan, South of Africa, South Sandwich Islands, Uzbekistan, Pakistan, Mexico, Oklahoma, Hindu Kush," (December 17, 2024)
Forecasts 168327, 168609 and 168596 had expected activity within about
100 km of today's event was likely in early January, 2025 or late December, 2024." (January 3, 2025)
and
"NEIC reported an earthquake of M 4.4 in El Salvador was felt with intensity up to III in the area(s) of El Salvador at Usulutan." (January 4, 2025)
and in the previous issue as
"NEIC reported an earthquake of M 4.5 in El Salvador was felt with intensity up to IV in the area(s) of El Salvador at Usulutan and III in Antiguo Cuscatlan.
EMSC reported moderate shaking in Nueva San Salvador." (January 5, 2025)
Today's event in El Salvador occurred shortly after an M-Class solar flare
(M2.4 #2980) and may have been promoted by SFE from that flare. Data for this flare from SWPC follow:

In the previous issue of this summary it was noted:
"Press reports indicate the mainshock occurred when a once-dormant volcano ( Dofen Mountain) came back to life with a vent eruption which included volcanic mud which covered roads. At least 80,000 people have bee evacuated from the area of the Afar Triangle. At least 30 homes have been destroyed and collapsed in the earthquakes and tremors according to Ethiopian government sources. There is also a major dam in the area which may be in danger of breakage. NEIC reported an M 5.0 was felt in the region of Addis Ababa, Ethiopia with intensity III. This follows the largest earthquake in the area in the past 35 years." (January 5, 2025)
The strongest earthquake in the U.S. or Canada today was an M 3.8 in the Maui region of Hawaii. This earthquake occurred near local solar midnight and may have been promoted by strong tidal stresses which maximize near this hour. The last earthquake in the Maui region of Hawaii with greater magnitude occurred on September 16, 2017 but all of the events of M>=3.8 in the region of northern Hawaii in the past 35 years have occurred about 200 km west of today's epicenter including the 2017 quake. The only event within about 100 km of today's M 3.8 epicenter in the past 35 years was an M 3.8 on November 17, 2000. When an M 4.7 occurred in northern Hawaii on March 9, 2017 this summary noted:
"An unusually large earthquake of M 4.7 also hit northwest of Hawaii today. This event was felt with maximum intensity IV in Hawaii at Kualapuu, Maunaloa, and II-III throughout much of the remainder of Hawaii including at Kalaupapa, Hoolehua, Kaunakakai, Lahaina, Waimanalo, Honolulu, Kailua, Lanai City, Wailuku, Kahului, Kaneohe, Kaaawa, Hauula, Aiea, Makawao, Pearl City, Haiku, Kahuku, Mililani, Kihei, Pearl Harbor, Waipahu, Kula, Kapolei, Kamuela, Hilo, Hanapepe, Hawaii. The location of Hawaii with respected to TC Enawo in the South Indian Ocean has been emphasized in previous summaries and may have been instrumental in the occurrence of this earthquake at this time." (March 9, 2017)
and at the time of the September , 2017 M 4.2 this summary noted:
"The strongest earthquakes in the U.S. or Canada today was an M 4.2 in northern Hawaii and an M 4.6 in the Fox Islands, Aleutians. NEIC reported this event was felt with intensity II-III in Hawaii at Kaneohe Bay, Kailua, Kaaawa, Waimanalo, Kaneohe, Honolulu, Hauula, Laie, Aiea, Pearl City, Mililani, Haleiwa, Wahiawa, Pearl Harbor, Waipahu, Mauna Loa, Waialua, Waianae, Kualapuu, Kaunakakai, Lahaina and in general within about 100 km of the epicenter. This event is well to the northwest of normal volcanic tremor which frequently shakes the region. The last earthquake of M>=4.2 within about 150 km of this epicenter in Oahu was an M 4.5 on June 21, 2013, the only such event in Hawaii in at least 25 year. Three others, including an M 4.7 on March 9, 2017 lay just outside the 150 km radius." (September 16, 2017)
Forecast 168627 had expected northern Hawaii near Maui could see enhanced seismicity in early January.

An earthquake of M 3.0 occurred today in Louisiana. This event occurred near local solar midnight and was felt with intensity IV in Texas at Karnack Waskom and in Mooringsport, Louisiana according to data from NEIC. A series of earthquakes in Louisiana occurred in December, 2024 following the major events of M 7.0 off northern California and the M 7.4 in Vanuatu. These events of M 3.0-3.1 were near the same epicenter as today's M 3.0 and occurred on December 19, 20 and 23, 2024. At that time this summary noted:
"EMSC reported an earthquake of M 3.2 in Louisiana was felt with moderate intensity up to II-III in the area(s) of Waskom, Louisiana. NEIC reported it with M 3.1 was felt with intensity up to IV in Louisiana at Mooringsport, Shreveport, III in Singer, and in Texas at Karnack and Marshall and perhaps as far as Arkansas. This continues a series in the region which began following the M 7.4 in Vanuatu of December 17 - at a distance of 105 degrees. These are likely FFA of that event." (December 23, 2024)
The only earthquake of significantly larger magnitude than M 3.0 in the past 10 years occurred in Louisiana occurred on January 27, 2024 and was noted in this summary at the time:
"An unusual earthquake of M 3.5 occurred today in Louisiana. NEIC reported it was widely felt with intensity up to V in Louisiana at Hall Summit. An M 2.5 foreshock was felt in the same area today. Light earthquakes occurred in this area of Louisiana in April an December, 2021 and in November, 2022 but none of these were larger than M 3.0. The last event in Louisiana within about 100 km of today's epicenter occurred more that 35 years ago. An M 4.3 about 150 km to the southwest of this epicenter occurred on September 2, 2013." (January 27, 2024)
Forecast 168688 had expected enhanced seismicity within Louisiana was likely
around January 3, 2025.

NEIC reported an earthquake of M 5.1 in Mindanao, Philippines was felt with intensity up to II-III in the area(s) of Mindanao, Philippines at Davao, Katangawan and Tagum. EMSC reported slight shaking in Mindanao at Tagum City and Davao City. PHIVOLCS reported intensity III in Lupon and Tarragona, Davao Oriental; Malungon, Sarangani; Tupi, South Cotabato and II in Governor Generoso and San Isidro, Davao Oriental and Matalam, Cotabato. Also felt lightly in City of General Santos, City of Davao and Davao Occidental. This event occurred near the height of a strong M4.1 solar flare (SWPC #2940) and may have been promoted by SFE from that flare.

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

The strongest earthquake in the world today was an M 6.2 in El Salvador. NEIC reported it was widely felt in El Salvador and surrounding areas with maximum intensity up to VI (Slight damage) in El Salvador at Nuevo Cuscatlan, Ayutuxtepeque, Delgado and V in La Libertad, Nueva San Salvador, San Alejo, Aguilares, Apopa, Ilopango, Mejicanos, San Salvador, Santo Tomas, Soyapango, San Sebastian, among others. It was also felt with intensity III-IV in Guatemala, Honduras, Nicaragua, Puerto Rico.
An aftershock of M 4.5 was reported with moderate intensity by EMSC in Nueva San Salvador.
EMSC reported strong shaking in El Salvador at Los Planes de Renderos, Soyapango, Mejicanos, Nueva San Salvador, San Salvador, San Miguel, and in Nicaragua at Nagarote, Managua.
The last earthquake in the area of El Salvador with M>=6.2 occurred on July 19, 2023 with M 6.5
and as an M 6.5 on September 22, 2021.
A series of foreshocks hit the region of El Salvador in early January, 2025. The
regional stability of El Salvador at this time was discussed in the January 3, 2025
issue of this summary as:
"An earthquake of M 4.0 occurred about 40 minutes after the event in Chile in
the area of El Salvador. This is probably a triggered earthquake from Chile. An M 5.6
hit the area on December 9, 2024 several days after the M 7.0 of Northern California
of December 5. At the time this summary reported:
"A moderately strong earthquake was widely felt in El Salvador today. NEIC reported this event with M 5.6 was felt with maximum intensity VI in La Union and IV in Anamoros, San Salvador, Santiago de Maria, Choluteca, and in Honduras at Bodega de Los Tangos, Yamaranguila, Marcala,; III in El Salvador at Gotera Morazan, Chirilagua and in Honduras at Choloma, Tegucigalpa, Las Tapias, Valle de Angeles, Yaguacire and La Esperanza among others.
This epicenter is located at 40 degrees (360/9) from the earthquake of M 7.0
off northern California of December 5 and was likely a far-field aftershock
of that event as previously described in this summary.
This earthquake is the strongest in El Salvador since an M 6.5 on July 19, 2023
and a similar M 5.6 on March 17, 2024." (December 9, 2024)
It is worthwhile to note that this epicenter in El Salvador is also at 40 degrees
from the M 6.1 in Chile today. Constructive interference at 40 degrees from
Northern California and Chile could enhance regional seismicity in El Salvador.
This type of regional seismic triggering is common before larger regional
events and El Salvador may see a strong earthquake in the next several days.
Forecasts 168327, 168609 and 168596 had expected activity within about
100 km of today's event was likely in early January, 2025 or late December, 2024." (January 3, 2025)
and
"NEIC reported an earthquake of M 4.4 in El Salvador was felt with intensity up to III in the area(s) of El Salvador at Usulutan." (January 4, 2025)
and in the previous issue as
"NEIC reported an earthquake of M 4.5 in El Salvador was felt with intensity up to IV in the area(s) of El Salvador at Usulutan and III in Antiguo Cuscatlan.
EMSC reported moderate shaking in Nueva San Salvador." (January 5, 2025)
Today's event in El Salvador occurred shortly after an M-Class solar flare
(M2.4 #2980) and may have been promoted by SFE from that flare. Data for this flare
from SWPC follow:

Volcanism related earthquakes in Ethiopia continued today with additional moderate earthquakes of
M 4.5, 4.5, 4.5, 4.6.
In the previous issue of this summary it was noted:
"Press reports indicate the mainshock occurred when a once-dormant volcano ( Dofen Mountain) came back to life with a vent eruption which included volcanic mud which covered roads.
At least 80,000 prople have bee evacuated from the area of the Afar Triangle. At least 30
homes have been destroyed and collapsed in the earthquakes and tremors according to Ethiopian
government sources. There is also a major dam in the area which may be in
danger of breakage. NEIC reported an M 5.0 was felt in the region of Addis Ababa, Ethiopia with intensity III. This follows the largest
earthquake in the area in the past 35 years." (January 5, 2025)
An earthquake of M 3.0 occurred today in Louisiana. This event occurred near local
solar midnight and was felt with intensity IV in Texas at Karnack Waskom and in Mooringsport, Louisiana according to data from NEIC.
NEIC reported an earthquake of M 5.2 in the Solomon Islands was felt with intensity up to II in the area(s) of the Solomon Islands in Honiara, Guadalcanal.
NEIC reported an earthquake of M 2.9 off northern California was felt with light intensity up to II in the area(s) of northern California at Santa Rosa and San Francisco.
NEIC reported an earthquake of M 3.0 in Central Alaska was felt with intensity up to III in the area(s) of Central Alaska at Eagle River.
NEIC reported an earthquake of M 5.1 in Mindanao, Philippines was felt with intensity up to II-III in the area(s) of Mindanao, Philippines at Davao, Katangawan and Tagum.

EARTHQUAKES AND VOLCANISM IN ETHIOPIA DAMAGES HOUSING
EARTHQUAKE SUMMARY FOR JANUARY 4, 2025
Volcanism related earthquakes in Ethiopia continued today with additional moderate earthquakes of M 5.0, 4.9, 4.9, 4.6. Press reports indicate the mainshock occurred when a once-dormant volcano ( Dofen Mountain) came back to life with a vent eruption which included volcanic mud which covered roads. At least 80,000 people have been evacuated from the area of the Afar Triangle. At least 30 homes have been destroyed and collapsed in the earthquakes and tremors according to Ethiopian government sources. There is also a major dam in the area which may be in danger of breakage. NEIC reported an M 5.0 was felt in the region of Addis Ababa, Ethiopia with intensity III. This follows the largest earthquake in the area in the past 35 years - an M 5.8 that was reported in the previous issue of this summary in part as:
"The strongest earthquakes in the world today were an M 5.7-5.8 and foreshocks of M 5.2 and M 5.5 in Ethiopia. This event was reported by NEIC to have been felt with maximum intensity VIII (with damage) in Afar, Ethiopia at Amibara and Awash; VII in Debre and VI in Debre Birhan, Amhara with V in Oromia, Ethiopia at Nazret, Nek'emte ana Asbe and IV in Addis Ababa, Dese, Gelemso and II-III in Debre Zeyit, Sebeta, Sendafa and Mojo and as far as Djibouti. EMSC reported strong shaking in Ethiopia at Bereh, Akaki Beseka, Bishoftu, Addis Ababa. The M 5.8 was preceded near local solar midnight by an M 5.5 near the same epicenter. This event was reported by NEIC to have been felt in Ethiopia with intensity VIII (with damage) in Afar at Amibara; VI in Awash, V in Asbe Teferi, IV in Addis Ababa, Harer and Sebeta, Ormia, Ethiopia. The is the strongest earthquake in Ethiopia in at least 35 years. An M 5.3 hit the region on February 13, 1993, the largest previously in this time period." (January 4, 2025)
This swarm was extensively covered in the previous summary. Readers are referred to that issue for further information.
Forecast 168598 ha expected enhanced seismicity within about 10 km of these
epicenters was likely around January 7, 2025.

An unusual earthquake of M 4.5 was also felt in Burundi, Africa today. NEIC reported it was felt with maximum intensity V in Burundi at Cibitoke and II in Kigali with IV in the Congo at Bukavu Sud-Kivu. This epicenter is at 135 degrees from both the M 7.0 in Northern California of December 5, 2024 and the M 7.4 in Vanuatu of December 17, 2024. This distance is at the eighth node (360/8X3 = 135 degrees) and it is likely, as with the activity to the northeast in Ethiopia that it was promoted by constructive interference at the eighth node of energy from these two sources. In the previous issues of this summary this had been cited as promoting the Ethiopia volcanic activity as:
"An earthquake of M 4.6 also occurred in the Awash region of Ethiopia today. NEIC reported it was felt with intensity up to III in Addis Ababa, Ethiopia. This epicenter is at the exact same distance from both earthquakes in Northern California of December 5 and from Vanuatu of December 17 (129.0 degrees). Constructive interference of energy from these sources may be energizing this seismicity." (December 23, 2024, December 24, 2024)
Today's event is the strongest in Burundi within about 200 km of this epicenter since an M 5.0 on June 10, 2021. The last event in the area with M>5 occurred on October 30, 2019. At the time this summary noted:
"The most unusual earthquake in the world today was an M 5.3 in D.R. Congo. NEIC reported it was felt with intensity IV in the Congo at Bukavu, and Nyanza, Rwanda. Intensity II-III was also reported from Rwanda at Kibuye and Kigali and from Bujumbura, Burundi. This is the strongest earthquake within about 250 km of this epicenter since an M 5.8 and 5.5 on August 7, 2015. No damage was reported with today's earthquake. It occurred within about one hour of local solar midnight and may have been promoted by high tidal stresses associated with the new moon of October 28." (October 30, 2019)
Forecast 168288 had expected this event was likely around December 31, 2004 within about 100 km of today's epicenter.

A third earthquake also occurred today in Africa - an M 4.4 in Zimbabwe. It was not reported felt. It occurred at 146 degrees from the M 7.0 off Northern California of December 5, 2024. This is the distance at which P- and s- seismic waves get reflected and refracted back to the surface after strong earthquakes. A series of events from both Vanuatu and Northern California have occurred at this distance from these mainshocks in the past several weeks and are probably FFA from them.
Today's event in Zimbabwe is the strongest within Zimbabwe within about 200 of this epicenter since events of M 4.9, 4.9 and 4.6 starting December 20 and lasting through December 23, 2024 and is probably part of that swarm. At the time this summary noted:
"An unusual earthquake of M 4.9 occurred today in Zimbabwe, southern Africa. NEIC reported maximum intensity III in Kariba, Mashonaland, West Zimbabwe and II in Lusaka, Zambia. It follows an M 5.3 to the east in the Cape Province of South Africa – an unprecedented event in modern times.
This epicenter in Zimbabwe is located at 146 degrees from the M 7.0 off northern California of December 5 and is a likely FFA from that event as reported in the previous issue of this summary:
"This epicenter is located at 149 degrees from the M 7.0 in Northern California of December 5 and may be a FFA of that event. A series of earthquakes in Africa have occurred at this distance (the shadow zone boundary and node 5) in Africa in the past several days" (December 22, 23, 2024)
Forecast 168799 had expected enhanced seismicity in southern Africa in early
January, 2025.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

Volcanism related earthquakes in Ethiopia continued today with additional moderate earthquakes of
M 5.0, 4.9, 4.9, 4.6. Press reports indicate the mainshock occurred when a once-dormant volcano ( Dofen Mountain) came back to life with a vent eruption which included volcanic mud which covered roads.
At least 80,000 prople have bee evacuated from the area of the Afar Triangle. At least 30
homes have been destroyed and collapsed in the earthquakes and tremors according to Ethiopian
government sources. There is also a major dam in the area which may be in
danger of breakage. NEIC reported an M 5.0 was felt in the region of Addis Ababa, Ethiopia with intensity III. This follows the largest
earthquake in the area in the past 35 years - an M 5.8 that was reported in
the previous issue of this summary in part as:
"The strongest earthquakes in the world today were an M 5.7-5.8 and foreshocks of M 5.2 and M 5.5 in Ethiopia. This event was reported by NEIC to have been felt with maximum intensity VIII (with damage) in Afar, Ethiopia at Amibara and Awash; VII in Debre and VI in Debre Birhan, Amhara with V in Oromia, Ethiopia at Nazret, Nek'emte ana Asbe and IV in Addis Ababa, Dese, Gelemso and II-III in Debre Zeyit, Sebeta, Sendafa and Mojo and as far as Djibouti.
EMSC reported strong shaking in Ethiopia at Bereh, Akaki Beseka, Bishoftu, Addis Ababa.
The M 5.8 was preceded near local solar midnight by an M 5.5 near the same
epicenter. This event was reported by NEIC to have been felt in Ethiopia with intensity VIII (with damage) in Afar at Amibara; VI in Awash, V in Asbe Teferi, IV in Addis Ababa, Harer and Sebeta, Ormia, Ethiopia. The is the strongest earthquake in Ethiopia in at least 35 years. An M 5.3
hit the region on February 13, 1993, the largest previously in this time period." (January 4, 2025)
An unusual earthquake of M 4.5 was also felt in Burundi, Africa today. NEIC reported it was felt
with maximum intensity V in Burundi at Cibitoke and II in Kigali with IV in the Congo at Bukavu Sud-Kivu.
This epicenter is at 135 degrees from both the M 7.0 in Northern California of December 5, 2024 and
the M 7.4 in Vanuatu of December 17, 2024. This distance is at the eighth node
(360/8X3 = 135 degrees) and it is likely, as with the activity to the northeast
in Ethiopia that it was promoted by constructive interference at the eighth
node of energy from these two sources. In the previous issues of this summary
this had been cited as promoting the Ethiopia volcanic activity as:
"An earthquake of M 4.6 also occurred in the Awash region of Ethiopia today. NEIC reported it was felt with intensity up to III in Addis Ababa, Ethiopia.
This epicenter is at the exact same distance from both earthquakes in Northern
California of December 5 and from Vanuatu of December 17 (129.0 degrees). Constructive
interference of energy from these sources may be energizing this seismicity." (December 23, 2024, December 24, 2024)
NEIC reported earthquake of M 4.8 and M 4.1 in Vanuatu were felt with intensity up to IV in the area(s) of Vanuatu at Vila Shefa.
NEIC reported an earthquake of M 5.3 in Central Vanuatu was felt with intensity up to IV in the area(s) of Central Vanuatu at Luganville, Sanma.
NEIC reported an earthquake of M 4.5 in El Salvador was felt with intensity up to IV in the area(s) of El Salvador at Usulutan and III in Antiguo Cuscatlan.

MODERATELY STRONG QUAKES SHAKE ETHIOPIA
EARTHQUAKE SUMMARY FOR JANUARY 3, 2025
The strongest earthquakes in the world today were an M 5.7-5.8 and foreshocks of M 5.2 and M 5.5 in Ethiopia. This event was reported by NEIC to have been felt with maximum intensity VIII (with damage) in Afar, Ethiopia at Amibara and Awash; VII in Debre and VI in Debre Birhan, Amhara with V in Oromia, Ethiopia at Nazret, Nek'emte ana Asbe and IV in Addis Ababa, Dese, Gelemso and II-III in Debre Zeyit, Sebeta, Sendafa and Mojo and as far as Djibouti. EMSC reported strong shaking in Ethiopia at Bereh, Akaki Beseka, Bishoftu, Addis Ababa. The M 5.8 was preceded near local solar midnight by an M 5.5 near the same epicenter. This event was reported by NEIC to have been felt in Ethiopia with intensity VIII (with damage) in Afar at Amibara; VI in Awash, V in Asbe Teferi, IV in Addis Ababa, Harer and Sebeta, Ormia, Ethiopia. This is the strongest earthquake in Ethiopia in at least 35 years. An M 5.3 hit the region on February 13, 1993, the largest previously in this time period.
This follows a series of moderate earthquakes in this region of Ethiopia which began on September 27, 2024. At the time this summary noted:
"NEIC reported this earthquake of M 4.9 in Ethiopia was felt with intensity up to IV in the area(s) of Ethiopia in Addis Ababa." (September 27, 2024)
"An earthquake also occurred in Ethiopia in the current swarm of events in that area. NEIC reported this earthquake of M 4.9 in Ethiopia was felt with intensity up to V in the area(s) of Ethiopia at Awash, Afar and III in Addis Ababa. EMSC reported intensity IV in Fentale, Ethiopia. This had been noted in the previous issue of this summary as:
Seismicity in the region of Ethiopia has been tied consistently to strong solar flares near local solar noon or midnight.
"An earthquake of M 4.6 also occurred in the Awash region of Ethiopia today. NEIC reported it was felt with intensity up to III in Addis Ababa, Ethiopia.
This epicenter is at the exact same distance from both earthquakes in Northern California of December 5 and from Vanuatu of December 17 (129.0 degrees). Constructive interference of energy from these sources may be energizing this seismicity." (December 23, 2024, December 24, 2024)
and
"The most unusual earthquake of the day was an M 5.0 in Ethiopia. This area has seen several minor earthquakes in the past 10 days with an M 4.5 on October 15 and an M 4.3 on October 17. This follows a long period of quiet in the seismicity of Ethiopia. Only on such event of M>=5 in Ethiopia has occurred in the past 10 years - an M 5.2 on March 24, 2018. The last active period of seismicity occurred in the summer of 2011 and included quakes of 5.7, 5.4 and 5.6 among others. Still today's event is at an unusual epicenter. The only event in the past 30 years within about 200 km of today's epicenter of M>=5 was an M 5.0 on February 26, 2007." (October 24, 2021)
"The most unusual earthquake of the day today was an M 4.6 in the border region
between Eritrea and Ethiopia. This has been an active area especially during periods of active solar and geomagnetic periods, often showing synchronicity with major solar flares. During the current solar quiet period, however the area has seen little moderate seismicity. The last earthquakes of M>=4.6 within about 300 km of this epicenter occurred September 11, 2019 and August 13, 2018. The last event of M>5 in this area was an M 5.6 on July 8, 2013." (June 6, 2022)
Not to disappoint, today's M 5.8 occurred as a major solar flare was occurring of X1.1 class (SWPC #2610) and an M 5.8 (#2650). The earthquake occurred near the peak of this flare. SWPC data for these flares follows:

Today's M 5.8 in Ethiopia is probably related to a regional fault which is opening up a new ocean basin in the Afar region of Ethiopia. This epicenter is near the shadow zone boundary of p- and s-waves from the M 6.8 in the Kuril Islands of December 28, 2024 and may have been further energized by seismic energy from that source - an FFA.
These earthquakes are both at 128.5 degrees from the mainshocks off northern
California (M 7.0, December 5, 2024) and the M 7.4 in Vanuatu of December 17, 2024 and may have been promoted by constructive interference of energy from those two sources.
Forecasts 168313 and 168598 had expected this activity was likely within about 100 km in Ethiopia at the end of December, 2024 or early January, 2025.

An earthquake of M 4.5 struck the area near Broken Hill, New South Wales, Australia. This is a mining town with a population less then 20,000. Local press reported the earthquake was felt with moderate intensity at Little Topar, Mutawintji and Broken Hill. NEIC reported intensity III in Broken Hill, NSW, Australia. A foreshock of M 2.6 occurred earlier in the day but was reported felt with light intensity in Broken Hill.
The last earthquake in Australia within about 200 km of this event in NSW with M>=4.5 occurred on August 13 and 14, 1996 nearly 30 years ago. Today;s event occurred near local solar noon and may have been promoted by strong tidal stresses with the new moon of December 30, 2024 as well as effects of solar flares (SFE) today.
This earthquake is located at 103 degrees from the M 5.8 in Ethiopia today - at the distance at which p- and s- seismic waves return to the surface after reflection and refraction off the core-mantle boundary. Enhanced seismicity at this distance from large surface events is often seen following the strong event. In this case the event in Australia occurred 3 hours after the M 5.8 in Ethiopia (and the coincidental X and M-class solar flares.

A moderate M 4.9 also occurred today in the North Atlantic Ridge. This is the strongest earthquake within about 250 km of this epicenter since an M 5.2 on October 16, 2024 and an M 5.0 on April 23, 2024.
This earthquake is located at 145 degrees from the M 7.4 in Vanuatu of December 17, 2024 and may have been promoted by energy from that source.
Forecast 168481 had expected enhanced seismicity within about 100 km of this epicenter was likely in late December, 2024 or early January, 2025.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

STRONG QUAKE IN NORTHERN CHILE
EARTHQUAKE SUMMARY FOR JANUARY 2, 2025
The strongest earthquake in the world today was an M 6.1 in northern Chile in
the Tarapaca district. NEIC reported it was felt with maximum intensity V in Antofagasta, Chile at Calama and Tocopilla and IV in Iquique, Tarapaca. Intensity II-III was felt in Chile at Arica, Antofagasta, Copiapo, and in Tacna and Arequipa, Peru; Cordoba, Argentina and Atacama Chile among others. EMSC reported strong shaking in Chile at Calama, San Pedro de Atacama, Alto Hospicio, Iquique. GUC reported intensity V Antofagasta at Mejillones, Tocopilla, Maria Elena, IV in Antofagasta, Calama, San Pedro de Atacama, Sierra Gorda, in Tarapaca with V at Alto Hospicio, Huara, Ujina, El Loa, IV in Iquique, Camina, La Tirana, Pozo Almonte, Pica, Pisagua, Cancosa III in Mamina, and IV in Arica and Parinacota at Codpa.
A major earthquake of M 7.7 hit near this area on April 4, 2014 but this is the strongest earthquake in the Antofagasta region of Chile since similar events of M 6.1 on July 27 and 28, 2022. AT the time this summary noted:
"Two strong earthquakes occurred in northern Chile today. These included an M 6.2 in eastern Antofagasta, northern Chile which was felt with intensity V in Calama, IV in Antofagasta, Iquique, and Bolivia and II-III in Arica, Copiapo, and Valparaiso, Chile. This was followed later in the day by an M 6.1 in Antofagasta which was felt with maximum intensity VII in Antofagasta in Tocopilla, with IV in Calaman, Antofagasta and Iquique and II-III in Moquegua, Arequipa. This activity is near the antipode of the M 7.0 which occurred in Luzon, Philippines on July 27, 2022 and had been anticipated in this summary in the previous issue as:
"The antipode to this earthquake (in Luzon, Philippines) is at 18S 60W in northern South America. Enhanced seismicity in this area from Chile to Peru and Bolivia is likely in the next several days due to antipodal focusing of energy from the event in Luzon." (July 27, 2022)
It is likely that this activity in northern Chile was also promoted by the new moon which arrives on July 28 as it occurred near the longitude and hour or maximum tidal stresses as noted in this and previous issues of this summary:
"The new moon will arrive at 17:55 UT on July 28, 2022. Longitudes which are near local solar noon at this time are near 90 West while those at solar midnight are near 90 East. These include eastern Mexico and Central America in the west as well as central U.S. and portions of western South America and the East Pacific Rise. In the east it includes areas of western Indonesia and Asia including India and Myanmar and China. These are area where tidal triggering is likely with this new moon. Other areas may also see triggering by tidal stresses in the next week." (July 24-27, 2022)
The last earthquake in Antofagasta, Chile within about 200 km of today's activity occurred on September 11, 2020 with M 6.3. A major M 7.6 hit north of this on April 3, 2014 and an M 7.7 hit near today's activity on November 14, 2007." (July 28, 2022)
A moderate regional foreshock occurred earlier in the day in the area of Salta, Argentina. This event may have been triggered by a moderate solar flare (#2350 C7.5) as it occurred near local solar midnight at the beginning of that flare. Data for this flare from SWPC follow.

An earthquake of M 4.0 occurred about 40 minutes after the event in Chile in the area of El Salvador. This is probably a triggered earthquake from Chile. An M 5.6 hit the area on December 9, 2024 several days after the M 7.0 of Northern California of December 5. At the time this summary reported:
"A moderately strong earthquake was widely felt in El Salvador today. NEIC reported this event with M 5.6 was felt with maximum intensity VI in La Union and IV in Anamoros, San Salvador, Santiago de Maria, Choluteca, and in Honduras at Bodega de Los Tangos, Yamaranguila, Marcala,; III in El Salvador at Gotera Morazan, Chirilagua and in Honduras at Choloma, Tegucigalpa, Las Tapias, Valle de Angeles, Yaguacire and La Esperanza among others. This epicenter is located at 40 degrees (360/9) from the earthquake of M 7.0 off northern California of December 5 and was likely a far-field aftershock of that event as previously described in this summary. This earthquake is the strongest in El Salvador since an M 6.5 on July 19, 2023 and a similar M 5.6 on March 17, 2024." (December 9, 2024)
It is worthwhile to note that this epicenter in El Salvador is also at 40 degrees from the M 6.1 in Chile today. Constructive interference at 40 degrees from Northern California and Chile could enhance regional seismicity in El Salvador.
This type of regional seismic triggering is common before larger regional events and El Salvador may see a strong earthquake in the next several days.
Forecasts 168327, 168609 and 168596 had expected activity within about 100 km of today's event was likely in early January, 2025 or late December, 2024.

Moderately strong earthquakes continued today in the region of the South Sandwich Islands. An M 5.5 was the largest today and was not reported felt by NEIC. This event occurred near local solar midnight and may have been promoted by strong tidal and/or geomagnetic effects which can maximize near this hour.
An M 6.1 hit this area yesterday and was reported in this summary as:
"The strongest earthquakes in the world today occurred in the southern oceans.
These included an M 6.1 in the South Sandwich Islands and an M 5.5 in the
Balleny Islands south of New Zealand and an M 5.2 in the Tristan da Cunha area of the South Atlantic. None of these were reported felt in their remote epicentral areas. The event in the South Sandwich Islands occurred within a few minutes of local solar noon and was probably promoted by strong tidal stresses associated with the super new moon of December 30 as noted in this and previous issues of this summary.
"The new moon (supermoon) will arrive on December 30, 2024 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland and the Atlantic Ridge while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/New Zealand and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this new moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this new moon are considered moderate to high in the next week (December 28-31, 2024 and January 1-4, 2025)." (December 27, 2024 to January 2, 2025)
The earthquake of M 6.1 in the South Sandwich Islands is at 102 degrees from the M 7.4 in Vanuatu of December 17, 2024 (shadow zone boundary and node 7) and was probably promoted by energy from that source. Likewise the M 5.2 in the Tristan da Cunha area of the south Atlantic is at the third node (120 degrees) from Vanuatu and was also a likely FFA from that event. An M 5.1 today in the Easter Island area of the South Pacific is at the ninth node (80 degrees) from both the M 7.0 in Northern California and from Vanuatu and may be a case of overlapping triggering at the same distance like as is being observed in Ethiopia in the current swarm there.
The last earthquake of M>=6.1 in the South Sandwich Islands occurred as an M 6.3 on October 25, 2022. A great M 8.1 hit the region on August 12, 2021." (January 2, 2025)
Forecast 168821 had expected today's event in the South Sandwich Islands was
likely within about 100 km around January 4, 2025.

A pair of moderately strong earthquakes also occurred today in the New Ireland, PNG region. The last event in this region of equal or larger magnitude was an M 5.5 on July 12, 2024 but an M 6.6 about 250 km to the southeast occurred on November 15, 2024. These epicenters are at the seventh node (51.4 degrees = 360/7) from the M 6.8 in the Kuril Islands of December 27, 2024 and near the fourth node (90 degrees) from the M 7.0 off Northern California of December 5 and may have been promoted by energy from those sources.
Forecast 168575 had expected enhanced seismicity in this region within about 50
km of these epicenters was likely around January 3, 2025.

The series of moderate earthquakes in Awash, Ethiopia continued today. Today's earthquakes with magnitude of M 4.5, M 4.7, 4.5, 4.7, and M 5.0 among others have been occurring throughout the past week and are being felt with intensity III in Addis Ababa, and IV in Asbe Teferi Oromia, Ethiopia. This may be related to regional volcanism and may expand with further activity of solar flares and geomagnetic storms, both of which accelerate regional volcanism and seismicity in Ethiopia.
Forecast 168598 had expected enhanced seismicity within about 100 km of these
events was likely in Ethiopia around January 1, 2025.

NEIC reported earthquakes of M 4.8 and M 4.9 in Eastern China was felt with intensity up to V in the area(s) of Eastern China at Yinchuan, Ningxia. Video of the shaking accompanying this earthquake series can be watched on the Internet. This is the strongest earthquake within about 200 km of this epicenter since an M 5.1 on June 15, 1991. The last event of larger magnitude within about 300 km was an M 5.3 on December 31, 2023. At the time this summary noted:
"The earthquake in Gansu, China of M 5.3 occurred near the Ningxia border.
NEIC reported this earthquake of M 5.3 in China was felt with intensity up to VII in the area(s) of China in Baiyin. It may have caused local damage but this was not immediately reported. This is the strongest earthquake within about 250 km of this epicenter since an M 4.3 on July 22, 2013 an event that followed the largest earthquake in the area in the past 35 years - an M 5.9 on July 21, 2013." (December 31, 2023)
Forecasts 168683 and 168411 had expected regional seismic enhancement within about 100 km of this epicenter was likely around December 30, 2024 to January 2, 2025.

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

The strongest earthquakes in the world today were an M 5.7-5.8 and foreshocks of M 5.2 and M 5.5 in Ethiopia. This event was reported by NEIC to have been felt with maximum intensity VIII (with damage) in Afar, Ethiopia at Amibara and Awash; VII in Debre and VI in Debre Birhan, Amhara with V in Oromia, Ethiopia at Nazret, Nek'emte ana Asbe and IV in Addis Ababa, Dese, Gelemso and II-III in Debre Zeyit, Sebeta, Sendafa and Mojo and as far as Djibouti.
EMSC reported strong shaking in Ethiopia at Bereh, Akaki Beseka, Bishoftu, Addis Ababa.
The M 5.8 was preceded near local solar midnight by an M 5.5 near the same
epicenter. This event was reported by NEIC to have been felt in Ethiopia with intensity VIII (with damage) in Afar at Amibara; VI in Awash, V in Asbe Teferi, IV in Addis Ababa, Harer and Sebeta, Ormia, Ethiopia. The is the strongest earthquake in Ethiopia in at least 35 years. An M 5.3
hit the region on February 13, 1993, the largest previously in this time period.
This follows a series of moderate earthquakes in this region of Ethiopia which
began on September 27, 2024. At the time this summary noted:
"NEIC reported this earthquake of M 4.9 in Ethiopia was felt with intensity up to IV in the area(s) of Ethiopia in Addis Ababa." (September 27, 2024)
"An earthquake also occurred in Ethiopia in the current swarm of events in
that area. NEIC reported this earthquake of M 4.9 in Ethiopia was felt with intensity up to V in the area(s) of Ethiopia at Awash, Afar and III in Addis Ababa.
EMSC reported intensity IV in Fentale, Ethiopia. This had been noted in the
previous issue of this summary as:
Seismicity in the region of Ethiopia has been tied consistently to strong solar
flares near local solar noon or midnight.
"An earthquake of M 4.6 also occurred in the Awash region of Ethiopia today. NEIC reported it was felt with intensity up to III in Addis Ababa, Ethiopia.
This epicenter is at the exact same distance from both earthquakes in Northern
California of December 5 and from Vanuatu of December 17 (129.0 degrees). Constructive
interference of energy from these sources may be energizing this seismicity." (December 23, 2024, December 24, 2024)
and
"The most unusual earthquake of the day was an M 5.0 in Ethiopia. This area
has seen several minor earthquakes in the past 10 days with an M 4.5 on October 15
and an M 4.3 on October 17. This follows a long period of quiet in the
seismicity of Ethiopia. Only on such event of M>=5 in Ethiopia has occurred
in the past 10 years - an M 5.2 on March 24, 2018. The last active period
of seismicity occurred in the summer of 2011 and included quakes of 5.7, 5.4 and 5.6 among others.
Still today's event is at an unusual epicenter. The only event in the past
30 years within about 200 km of today's epicenter of M>=5 was an M 5.0 on February 26, 2007." (October 24, 2021)
"The most unusual earthquake of the day today was an M 4.6 in the border region
between Eritrea and Ethiopia.
This has been an active area especially during periods of active solar and geomagnetic
periods, often showing synchronicity with major solar flares. During the current
solar quiet period, however the area has see little moderate seismicity.
The last earthquakes of M>=4.6 within about 300 km of this epicenter occurred
September 11, 2019 and August 13, 2018. The last event of M>5 in this area
was an M 5.6 on July 8, 2013." (June 6, 2022)
Not to disappoint, today's M 5.8 occurred as a major solar flare was occurring
of X1.1 class (SWPC #2610) and an M 5.8 (#2650). The earthquake occurred near the peak of this flare.
SWPC data for these flares follows:

Today's M 5.8 in Ethiopia is probably related to a regional fault which is opening up a new ocean basin
in the Afar region of Ethiopia. This epicenter is near the shadow zone boundary
of p- and s-waves from the M 6.8 in the Kuril Islands of December 28, 2024
and may have been further energized by seismic energy from that source - an FFA.
An earthquake of M 4.5 struck the area near Broken Hill, New South Wales, Australia.
This is a mining town with a population less then 20,000. Local press reported the
earthquake was felt wiht moderate intensity at Little Topar, Mutawintji and Broken Hill.
NEIC reported intensity III in Broken Hill, NSW, Australia.
A foreshock of M 2.6 occurred earlier in the day but was reported felt with light intensity in Broken Hill.
The last earthquake in Australia within about 200 km of this event in NSW with M>=4.5
occurred on August 13 and 14, 1996 nearly 30 years ago. Today;s event occurred
near local solar noon and may have been promoted by strong tidal stresses
with the new moon of December 30, 2024 as well as effects of solar flares (SFE)
today.
NEIC reported an earthquake of M 4.4 in El Salvador was felt with intensity up to III in the area(s) of El Salvador at Usulutan.

MODERATE M 4.7 QUAKE STIRS NORTHERN CALIFORNIA GEYSERS REGION
EARTHQUAKE SUMMARY FOR JANUARY 1, 2025
The strongest earthquake in the U.S. or Canada today was an M 4.7 in the Geysers region of Northern California. Press reported the earthquake was felt as far as San Francisco as a rolling motion. While some minor damage was reported no significant damage was noted. More than 1500 people reported to the USGS that they had felt this earthquake. Maximum intensity occurred as VI at Sacramento with V in California at Kelseyville, Middletown, III in San Francisco, Calistoga, Fairfield, Hercules, Saint Helena, Yountville, Oakland, San Rafael, San Anselmo, Sausalito, Santa Rosa, Clearlake, Cloverdale, Geyserville, Glenhaven, Healdsburg, Hopland, Lakeport, Lower Lake, Monte Rio, Nice, Hidden Valley Lake. It was felt lightly in areas as far as 250 km from the epicenter in Nevada, and Central California. EMSC reported moderate shaking in northern California at Kelseyville, Middletown, Healdsburg, Petaluma, Fairfield, Vallejo, Pinole, and San Francisco. This earthquake is near the fourth node (90 degrees) from the M 7.4 in Vanuatu of December 17, 2024 and may be an FFA of that event. Also like many of the larger events in the California Geysers area this was closely associated with the supermoon of December 30, 2024 and with the strongest geomagnetic storm in nearly three months, both of which probably helped promote today's M 4.7 in northern California. The last earthquake in
the Geysers area of California within about 100 km of today's epicenter with
M>=4.7 occurred on December 14, 2016 with M 5.0. The largest earthquake in the area and the only of M>6.0 in the past 35 years occurred as an M 6.0 near Napa on August 24, 2014. At the time of the 2016 earthquake this summary noted:
"The strongest earthquake in California today was an M 5.0 north of San Francisco in the Geysers area of California. NEIC reported the mainshock was felt with intensity up to VI (minor damage) with reports of intensity V from Kelseyville; IV from Geyserville, Cloverdale, Middletown, Lakeport, Lower Lake, Cazadero, Upper Lake, Mendocino, and in general within about 100 km of the epicenter. Lesser shaking was reported from as far away as 470 km at Nipomo but these reports probably refer to the Templeton earthquake in central California. Lesser shaking associated with the Geysers event probably was limited to areas within about 150 km of that epicenter including, but not limited to San Mateo, San Rafael, Vacaville, Fairfield, Napa, Sonoma, Petaluma, Potter Valley, Yountville, Bodega Bay, Rohnert Park, Saint Helena, Santa Rosa, Ukiah, Sebastopol, Angwin, Healdsburg, Hopland, Hidden Valley Lake, Lucerne, Clearlake, Windsor, Calistoga, Guerneville, and Forestville, California.
Aftershocks were felt with intensity II-III in Lakeport, Calistoga, Sebastopol, Ukiah, Saint Helena, Cloverdale, Healdsburg, Windsor, Santa Rosa and San Francisco, California. No major damage was reported with this earthquake. It is the strongest earthquake in the Geysers area within about 50 km of this epicenter in at least 25 years. Earthquakes hit the Napa area with M 6.0 on August 24, 2014 and with M 5.0 on September 3, 2000. While smaller earthquakes in the Geysers, California are nearly continuous, events of larger magnitude are uncommon. Today's earthquake may be the largest ever recorded in the Geysers area, in fact. An M 5.0 was recorded on May 7, 1955 but magnitudes were not well determined at the time. No other events in the Geysers area have reached M>=5.0 until today." (December 14, 2016)
This earthquake occurred near the peak of a severe geomagnetic storm. This storm reached maximum KP of 8 within about an hour of local solar noon in California and probably helped trigger today's earthquake in northern California. High latitude AP reached index of 113 on January 1 with middle latitude AP 48 and
Planetary index of 86. This is the strongest geomagnetic storm since AP reached 116 on October 11, 2024 with middle latitude AP of 123. In the past two issues this summary had anticipated this seismicity and geomagnetic storm as:
These events occurred near local solar midnight and were probably promoted by strong tidal stresses with today's new moon which maximized near this hour. This summary had expected enhanced seismicity with this super-moon in previous issues of this summary as:
"While global seismicity today was at relative moderate levels, several factors in the next three days will probably move to enhance to possibility of significant seismicity at the end of 2024. The first of these is the occurrence of a super-moon on December 30,, 2024 as reported in earlier issues of this summary:
"The new moon will arrive on December 30, 2024. This is a super moon - nearer than normal for new moons. This summary notes the likely influence on global seismicity of these increased tides as:
The new moon (supermoon) will arrive on December 30, 2024 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland and the Atlantic Ridge while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/New Zealand and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this new moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this new moon are considered moderate to high in the next week (December 28-31, 2024 and January 1-4, 2025)." (December 27-29, 2024)
The activity in Coquimbo, Chile may have been triggered by SFE associated with a strong X-class solar flare (X1.2 preliminary). It occurred at the tail end of this flare near local solar midnight, both factors likely to help trigger seismicity." (December 31, 2024)
The history of seismic activity in the Geysers area of California had been summarized in this summary when a series of events in the Geysers region followed the M 7.0 off the coast of Northern California on December 5, 2024 as:
A series of moderate earthquake in the Geysers area of northern California followed the M 7.0 off the California coast. They were likely triggered by P- and/or S-waves from that earthquake. This series included events of M 2.5 and 4.3. NEIC reported these were felt with intensity up to III in northern and Central California at Felton, San Jose, Santa Rosa, Yuba City, Rohnert Park and Fremont.
The last earthquake in the Geysers area of California with M>=4.3 occurred
September 7, 2024 with M 4.3, the last of larger magnitude was an M 4.5 on June 8, 2024. At the time this summary noted:
"The strongest earthquake in the U.S. or Canada today was an M 4.5 in Northern California. NEIC reported it was felt with maximum intensity V in the Geysers, California. This earthquake occurred within minutes of local solar noon and was probably promoted by strong tidal stresses which maximize near this hour. EMSC reported strong shaking in Middletown, California. The last earthquake in the Geysers area of Northern California with M>=4.5 occurred on June 3, 2023 more than a year ago with M 4.5. The last event in the area of larger magnitude occurred as an M 5.0 on December 14, 2016.
"The strongest earthquake in the U.S. or Canada today was an M 4.5 in the Geysers region of Northern California. NEIC reported it was felt with maximum intensity IV in Kelseyville and Middletown with intensity II-III in Geyserville, Healdsburg, Hidden Valley Lake, Cloverdale, Lower Lake, Calistoga, Windsor and as far to the south as San Francisco, California. This is an area where fluid flow often controls seismicity. Strong tidal stresses can be an effective means to move fluids. So it is not surprising that this earthquake occurred in conjunction with today's full moon
...
Today's earthquake is the strongest event in the Geysers area since an M 5.0 on December 14, 2016. That earthquake was likely the strongest recorded in the Geysers region of California as reported at the time in this summary:
"While smaller earthquakes in the Geysers, California are nearly continuous, events of larger magnitude are uncommon. Today's earthquake may be the largest ever recorded in the Geysers area, in fact. An M 5.0 was recorded on May 7, 1955 but magnitudes were not well determined at the time. No other events in the Geysers area have reached M>=5.0 until today." (December 14, 2016, June 8, 2024, December 6, 2024)
Forecasts 168645 and 168372 had expected today's M 4.7 was likely within about 10 km of the epicenter around December 30, 2024 - January 1, 2025.

The earthquake in California was preceded several hours earlier by an M 3.0 in northwestern Nebraska. This earthquake occurred near local solar noon and was felt with intensity III in Nebraska at Halsey, Mullen, Valentine and II in Omaha and Wood Lake and possibly in Iowa. This pattern of an unusual quake in Nebraska or South Dakota followed by a significant quake along the North America-Pacific plate boundary has been previously documented in this summary, for example before the M 7.0 off northern California on December 5, 2024 as:
"... Some interesting foreshock activity had been noted before the M 7.0 off northern California. For example an M 2.8 in Nebraska had been cited as a possible precursor to such an event as:
"Unusual light earthquakes occurred today in the U.S. and were felt in Massachusetts (M about 2.3) near Worchester, MA and in Nebraska near Houston (M 2.8). Light seismicity in these areas often precedes strongly enhanced seismicity along the Pacific-North American plate boundary by hours to days. Increased seismicity along this boundary may be anticipated in the next several days including a slight possibility of a moderate to large regional event." (November 21, 2024, December 8, 2024)
A series of earthquakes about 100 km south of today's epicenter last occurred in 2018. The last of these of M>=3 was an M 3.0 on December 13, 2018 but the largest was an M 4,2 on June 30, 2018. At the time this summary noted:
"The most unusual and largest earthquake in the U.S. or Canada outside Hawaii today was an M 4.2 in Nebraska. NEIC reported it was felt with intensity IV in Nebraska at Arnold and North Platte and II-III in Callaway, Stapleton, Brady. Earthquakes in this area often precede by hours to days moderate to strong earthquakes along the western rim of the North American Plate. These are usually in the region of Alaska but can occur as far south as California." (June 30, 2018)
O: 1JAN2025 20:57:55 42.3N 100.6W ML=3.0 EMSC NEBRASKA
The strongest earthquakes in the world today occurred in the southern oceans. These included an M 6.1 in the South Sandwich Islands and an M 5.5 in the
Balleny Islands south of New Zealand and an M 5.2 in the Tristan da Cunha area of the South Atlantic. None of these were reported felt in their remote epicentral areas. The event in the South Sandwich Islands occurred within a few minutes of local solar noon and was probably promoted by strong tidal stresses associated with the super new moon of December 30 as noted in this and previous issues of this summary.
"The new moon (supermoon) will arrive on December 30, 2024 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland and the Atlantic Ridge while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/New Zealand and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this new moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this new moon are considered moderate to high in the next week (December 28-31, 2024 and January 1-4, 2025)." (December 27, 2024 to January 2, 2025)
The earthquake of M 6.1 in the South Sandwich Islands is at 102 degrees from the M 7.4 in Vanuatu of December 17, 2024 (shadow zone boundary and node 7) and was probably promoted by energy from that source. Likewise the M 5.2 in the Tristan da Cunha area of the south Atlantic is at the third node (120 degrees) from Vanuatu and was also a likely FFA from that event. An M 5.1 today in the Easter Island area of the South Pacific is at the ninth node (80 degrees) from both the M 7.0 in Northern California and from Vanuatu and may be a case of overlapping triggering at the same distance like as is being observed in Ethiopia in the current swarm there.
The last earthquake of M>=6.1 in the South Sandwich Islands occurred as an M 6.3 on October 25, 2022. A great M 8.1 hit the region on August 12, 2021. At the time of the event in 2022 this summary noted:
"The strongest earthquake in the world today was an M 6.3 in the area of the South Sandwich Islands, South Atlantic. It was not reported felt in this remote area. It occurred near local solar midnight and may have been promoted by energy associated with the solar eclipse and new moon today and/or by the strong mid-latitude geomagnetic storm finishing up today. This area had been expected to see enhanced seismicity with this new moon as noted in previous issues of this summary:
It is also likely to have been promoted by the geomagnetic storm at mid-latitudes which continued today reaching A-index disturbance at mid-latitudes of 204, the highest recorded by SWPC since at least 1994.
The last earthquake in the South Sandwich Islands within about 250 km of this epicenter with M>=6.3 was an M 6.9 on August 16, 2021, itself an aftershock of the M 7.5 of August 12, 2021. A more recent event of M 6.7 occurred on September 29, 2022 about 500 km southeast of this epicenter in the South Atlantic region." (October 25, 2022)
As well as being promoted by tidal and geomagnetic effects the area of the South Sandwich Islands was also possibly triggered by SFE from Solar Flares
#2150 and 2170 (SWPC) which were coincident with this earthquake. An M 4.7 foreshock in the South Sandwich Islands about three hours earlier also occurred at the maximum of solar flare 2110, suggesting the possibility of a stronger regional event to follow. SWPC data for these flares follow:

The M 5.5 in the Balleny Islands which was not felt occurred 20 minutes after the M 4.7 in the Geysers, California. It is located at 120 degrees (node 3) from the California event and may have been promoted by energy from that source. It, like the event of M 6.1 in the South Sandwich Islands today occurred near local solar noon and may have been promoted by effects related to the new moon of December 30, 2024 and/or the geomagnetic storm today both of which maximize near local solar noon. The last earthquake within about 200 km of this epicenter in the Balleny Islands of M>=5.5 occurred on November 15, 2024 with M 5.5 but the last with greater magnitude of M 6.0 on June 16, 2024 had been noted in this summary as:
"The strongest earthquake in the world today was an M 6.0 in the Balleny/Macquarie Island area south of Australia and New Zealand. It was not felt in this remote area. This joins a series of moderately large earthquakes along the Antarctic Ridge over the past several days including a series to the east in the Pacific-Antarctic Ridge and the South Sandwich Islands (M 5.4) and events south of Australia and on the Mid-Indian Ridge (M 5.8) today. These high latitude events suggest a geomagnetic effect on their timing. Many of these occurred with a geomagnetic storm which today reached Planetary AP of 19 and 26 at high latitudes, the second strongest geomagnetic storm of the past month (after June 7, 2024). This geomagnetic storm is likely to continue for several more days and could bring enhanced global seismicity in this time period. The earthquake in the Macquarie Ridge is near-Antipodal to the continuing eruption of volcanoes in southern Iceland and the two area are likely promoting regional activity in these two regions. The relation between earthquakes in Macquarie and Iceland has been noted in previous issues of this summary for example on March 5, 2024 as:
" ... Macquarie Island area around March 4, 2024. It is near the antipode of the energetic volcanic eruption in southern Iceland and may have been promoted by energy from that source." (March 5, 2024)
and on April 1, 2024 as:
"The strongest earthquake in the world today was an M 5.9 in the Balleny Islands south of New Zealand. The epicenter of this unfelt earthquake is exactly antipodal to the strong volcanic eruption in southern Iceland which has been ongoing for several weeks. It is likely that today's earthquake in the Balleny Islands was promoted by antipodal focusing of energy from the volcanic eruption in Iceland. Compare the eruption coordinates (63N 24W) with the epicenter of the M 5.9 in the Balleny Islands today (63S 156E) for antipodality. The last earthquake in the Balleny Islands with M>=5.9 occurred on July 6, 2023 also in connection with a volcanic eruption in Iceland. At the time this summary noted this relation as:
"The volcanic swarm of earthquakes in Iceland continued today near Reykjavik where many of the moderate quakes in this swarm were felt today. A volcanic warning has been issued by Icelandic authorities as more than 2000 light to moderate quakes have occurred in this region in the past two days.
...
NEIC reported these earthquake of M 4.2-4.5 in Iceland was felt with intensity II-III in the area(s) of Iceland in Keflavik, Suournes. The antipode of today's activity in Iceland is in the Balleny Islands south of Australia and New Zealand at 63S 156E. Some enhanced seismicity in this area is likely with the swarm in Iceland.
...
The strongest earthquake of the day occurred near the antipode of the tremors in Iceland. This event of M 5.9 in the Balleny Islands was not reported felt in this remote epicentral area. This event occurred simultaneously with Solar Flare 7970, the strongest solar of the day and was probably promoted by Solar Flare Effects (SFE) associated with that flare." (July 6, 2023)
Also on January 11, 2024, a strong volcanic eruption in Iceland was related in this summary to the Balleny Islands as:
"An earthquake of M 4.5 occurred today in northeastern Iceland. NEIC reported it was felt with intensity up to VI in Hofn, Iceland. This follows a pair of antipodal earthquake in the Balleny Islands two day ago. At the time this summary noted in this regard:
"A series of moderate to strong earthquakes hit today at epicenters which were the antipodes of active volcanism. The strongest of these was an M 5.6-6.0 in the Balleny Islands south of New Zealand. This is exactly opposite on the earth to Iceland where volcanism has been active over the past several weeks and months.
...
The earthquake in the Balleny Islands was the strongest in that region in at least three years. A smaller M 5.5 hit the area on June 27, 2011. The last earthquakes of similar or larger magnitude in the region occurred on April 12, and April 16, 2007 with M 6.0 and 5.8.
The Balleny Islands are a remote sparsely populated region and today's earthquake was not reported felt in the region. Followers of the P103 theory may be interested to note that this epicenter is located at 103 degrees from the mainshock in Japan of March 11. This suggest that some triggering is possible at this distance from great earthquake because seismic energy is concentrated at the surface at this distance." (July 21, 2011)
It is important to note that this summary written nearly 13 years ago is completely congruous with the current situation following a major quake in Japan at 103 degrees and a major eruption near the antipode in Iceland." (January 8, 2024)
The earthquake in Iceland was the beginning of a new eruption. Bubbling lava could be seen on video on the web. Another area where a volcanic eruption is occurring is in Mount Lewotobi Laki-Laki in Indonesia. This volcano is on Flores
Island. Thousands have been evacuated following several days of eruption in this area." (January 11, 2024, April 1, 2024, June 16, 2024)
Today's earthquake in the Balleny Islands is at the third node (120 degrees) from the M 7.0 off Northern California of December 5, 2024 and at the eighth node (45 degrees) from the M 7.4 in Vanuatu of December 17, 2024 and may be FFA from both these events.
The eruption in Iceland continued unabated today. It is at the antipode of the M 5.5 in the Balleny Island region.
The series of moderate earthquakes in Awash, Ethiopia continued today. Today's earthquakes with magnitude of M 4.2, M 5.1, 4.9, 4.6, and M 4.6 among others have been occurring throughout the past week and are being felt with intensity III in Addis Ababa, and IV in Asbe Teferi Oromia, Ethiopia.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

the Tarapaca district. NEIC reported it was felt with maximum intensity V in Antofagasta, Chile at Calama and Tocopilla and IV in Iquique, Tarapaca. Intensity II-III was felt in Chile at Arica, Antofagasta, Copiapo, and in Tacna and Arequipa, Peru; Cordoba, Argentina and Atacama Chile among others.
EMSC reported strong shaking in Chile at Calama, San Pedro de Atacama, Alto Hospicio, Iquique.
GUC (local network) reported this earthquake with the following parameters.
02-01-2025 20:43 21.7S 69.0W 98 6.1 V Antofagasta at Mejillones, Tocopilla, Maria Elena, IV in Antofagasta, Calama, San Pedro de Atacama, Sierra Gorda, in Tarapaca with V at Alto Hospicio, Huara, Ujina, El Loa, IV in Iquique, Camina, La Tirana, Pozo Almonte, Pica, Pisagua, Cancosa III in Mamina, and IV in Arica and Parinacota at Codpa.
A major earthquake of M 7.7 hit near this area on April 4, 2014 but this is the strongest earthquake in the Antofagasta region of Chile since
similar events of M 6.1 on July 27 and 28, 2022. AT the time this summary noted:
"Two strong earthquake occurred in northern Chile today. These included an M 6.2 in eastern Antofagasta, northern Chile which was felt with intensity V in Calama, IV in Antofagasta, Iquique, and Bolivia and II-III in Arica, Copiapo, and Valparaiso, Chile.
This was followed later in the day by an M 6.1 in Antofagasta which was felt with maximum intensity VII in Antofagasta in Tocopilla, with IV in Calaman, Antofagasta and Iquique and II-III in Moquegua, Arequipa.
This activity is near the antipode of the M 7.0 which occurred in Luzon, Philippines
on July 27, 2022 and had been anticipated in this summary in the previous issue as:
"The antipode to this earthquake (in Luzon, Philippines) is at 18S 60W in northern South America. Enhanced
seismicity in this area from Chile to Peru and Bolivia is likely in the next
several days due to antipodal focusing of energy from the event in Luzon." (July 27, 2022)
It is likely that this activity in northern Chile was also promoted by the new moon
which arrives on July 28 as it occurred near the longitude and hour or maximum
tidal stresses as noted in this and previous issues of this summary:
"The new moon will arrive at 17:55 UT on July 28, 2022. Longitudes which are near local solar noon at this time are near 90 West while those at solar midnight are near 90 East. These include eastern Mexico and Central America in the west as well as central U.S. and portions of western South America and the East Pacific Rise. In the east it includes areas of western Indonesia and Asia including India and Myanmar and China. These are area where tidal triggering is likely with this new moon. Other areas may also see triggering by tidal stresses in the next week." (July 24-27, 2022)
The last earthquake in Antofagasta, Chile within about 200 km of today's activity
occurred on September 11, 2020 with M 6.3. A major M 7.6 hit north of this on April 3, 2014
and and M 7.7 hit near today's activity on November 14, 2007." (July 28, 2022)
A moderate regional foreshock occurred earlier in the dat in the area of Salta, Argentina.
This event may have been triggered by a moderate solar flare (#2350 C7.5) as it
occurred near local solar midnight at the beginning of that flare. Data for
this flare from SWPC follow.

Moderately strong earthquakes continued today in the region of the South Sandwich Islands. An M 5.5 was the largest today and was not reported felt by NEIC.
An M 6.1 hit this area yesterday and was reported in this summary as:
"The strongest earthquakes in the world today occurred in the southern oceans.
These included an M 6.1 in the South Sandwich Islands and an M 5.5 in the
Balleny Islands south of New Zealand and an M 5.2 in the Tristan da Cunha area of the
South Atlantic. None of these were reported felt
in their remote epicentral areas. The event in the South Sandwich Islands occurred
within a few minutes of local solar noon and was probably promoted by strong
tidal stresses associated with the super new moon of December 30 as noted
in this and previous issues of this summary.
"The new moon (supermoon) will arrive on December 30, 2024 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland and the Atlantic Ridge while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/New Zealand and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this new moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this new moon are considered moderate to high in the next week (December 28-31, 2024 and January 1-4, 2025)." (December 27, 2024 to January 2, 2025)
The earthquake of M 6.1 in the South Sandwich Islands is at 102 degrees from
the M 7.4 in Vanuatu of December 17, 2024 (shadow zone boundary and node 7)
and was probably promoted by energy from that source. Likewise the M 5.2 in
the Tristan da Cunha area of the south Atlantic is at the third node (120 degrees)
from Vanuatu and was also a likely FFA from that event. An M 5.1 today in the Easter
Island area of the South Pacific is at the ninth node (80 degrees) from both
the M 7.0 in Northern California and from Vanuatu and may be a case of overlapping triggering
at the same distance like as is being observed in Ethiopia in the current swarm there.
The last earthquake of M>=6.1 in the South Sandwich Islands occurred as an M 6.3 on October 25, 2022. A great M 8.1 hit the
region on August 12, 2021." (January 2, 2025)
The series of moderate eathquakes in Awash, Ethiopia continued today. Today's earthquakes
with magnitude of M 4.5, M 4.7, 4.5, 4.7, and M 5.0 among others have been occurring throughout the past week and are
being felt with intensity III in Addis Ababa, and IV in Asbe Teferi Oromia, Ethiopia.
NEIC reported earthquakes of M 4.8 and M 4.9 in Eastern China was felt with intensity up to V in the area(s) of Eastern China at Yinchuan, Ningxia.
Video of the shaking accompanying this earthquake series can be watched on the
Internet.
NEIC reported an earthquake of M 2.6 in Western Texas was felt with intensity up to II in the area(s) of Western Texas at Big Spring.
NEIC reported an earthquake of M 5.0 in India was felt with intensity up to IV in the area(s) of India in Silchar, Assam and II in Dibrugarh, Gauhati, Jorhat and Shillong, Meghalaya and in Bangladesh with III in Dacca, Silhat and Tungi.
EMSC reported mild shaking in India at Lamphel, Rongpur, Ashit Nagar, Beltola, Dimaruguri, Mathura Nagar, Beltola Tiniali, Sarumotoria, Sahib Tila, Bhangagarh.
NEIC reported an earthquake of M 2.6 in Southern California was felt with intensity up to III in the area(s) of Southern California at Banning, Moreno Valley and II in Burbank, Cardiff by the Sea, Cathedral City, Palm Springs and White Water.
NEIC reported an earthquake of M 3.8 in Southern Alaska was felt with intensity up to II-III in the area(s) of Southern Alaska at Anchorage, Wasilla and Eagle River.
EMSC reported an earthquake of M 4.4 in Eastern Kazakhstan was felt with intensity up to IV in the area(s) of Eastern Kazakhstan at Taldykorgan, Qonaev, and Almaty.
EMSC reported an earthquake of M 3.9 in Nepal was felt with intensity up to IV in the area(s) of Nepal at Kathmandu.
BMG reported an earthquake of M 5.2 in The Molucca Sea was felt with moderate intensity up to II in the area(s) of Kab Bolaang MongondowTimurat Nuangan and Motongkad and in Kota Kotamobagu.
This event may have been triggered by SFE from Solar Flare 2320 as it occurred
near local solar noon near the peak output of that flare.

January 2, 2025
The strongest earthquake in the U.S. or Canada today was an M 4.7 in the Geysers
region of Northern California. Press reported the earthquake was felt as far
as San Francisco as a rolling motion. While some minor damage was reported
no significant damage was noted. More than 1500 people reported to the USGS
that they had felt this earthquake. Maximum intensity occurred as VI at Sacramento with V in California at Kelseyville, Middletown, III in San Francisco, Calistoga, Fairfield, Hercules, Saint Helena, Yountville, Oakland, San Rafael, San Anselmo, Sausalito, Santa Rosa, Clearlake, Cloverdale, Geyserville, Glenhaven, Healdsburg, Hopland, Lakeport, Lower Lake, Monte Rio, Nice, Hidden Valley Lake. It was felt lightly in areas as far as 250 km from the epicenter in Nevada, and Central California.
EMSC reported moderate shaking in northern California at Kelseyville, Middletown, Healdsburg, Petaluma, Fairfield, Vallejo, Pinole, and San Francisco.
This earthquake is near the fourth node (90 degrees) from the M 7.4 in Vanuatu
of December 17, 2024 and may be an FFA of that event. Also like many of the
larger eventss in the California Geysers area this was closely associated
with the supermoon of December 30, 2024 and with the strongest geomagnetic
storm in nearly three months, both of which probably helped promote today's
M 4.7 in northern California. The last earthquake in
the Geysers area of California within about 100 km of today's epicenter with
M>=4.7 occurred on December 14, 2016 with M 5.0. The largest earthquake in the area
and the only of M>6.0 in the past 35 years occurred as an M 6.0 near Napa on
August 24, 2014. At the time of the 2016 earthquake this summary noted:
"The strongest earthquake in California today was an M 5.0 north of San Francisco
in the Geysers area of California. NEIC reported the mainshock was felt with intensity up to VI (minor damage) with reports of intensity V from Kelseyville; IV from Geyserville, Cloverdale, Middletown, Lakeport, Lower Lake, Cazadero, Upper Lake, Mendocino, and in general within about 100 km of the epicenter. Lesser shaking was reported from as far away as 470 km at Nipomo but these reports
probably refer to the Templeton earthquake in central California. Lesser shaking
associated with the Geysers event probably was limited to areas within about
150 km of that epicenter including, but not limited to San Mateo, San Rafael, Vacaville, Fairfield, Napa, Sonoma, Petaluma, Potter Valley, Yountville, Bodega Bay, Rohnert Park, Saint Helena, Santa Rosa, Ukiah, Sebastopol, Angwin, Healdsburg, Hopland, Hidden Valley Lake, Lucerne, Clearlake, Windsor, Calistoga, Guerneville, and Forestville, California.
Aftershocks were felt with intensity II-III in Lakeport, Calistoga, Sebastopol, Ukiah, Saint Helena, Cloverdale, Healdsburg, Windsor, Santa Rosa and San Francisco, California.
No major damage was reported with this earthquake. It is the strongest earthquake
in the Geysers area within about 50 km of this epicenter in at least 25 years.
Earthquakes hit the Napa area with M 6.0 on August 24, 2014 and with M 5.0 on September 3, 2000.
While smaller earthquakes in the Geysers, California are nearly continuous, events
of larger magnitude are uncommon. Today's earthquake may be the largest ever
recorded in the Geysers area, in fact. An M 5.0 was recorded on May 7, 1955 but
magnitudes were not well determined at the time. No other events in the Geysers
area have reached M>=5.0 until today." (December 14, 2016)
This earthquake occurred near the peak of a severe geomagnetic storm. This storm reached
maximum KP of 8 within about an hour of local solar noon in California
and probably helped trigger today's earthquake in northern California. High
latitude AP reached index of 113 on January 1 with middle latitude AP 48 and
Planetary index of 86. This is the strongest geomagnetic storm since AP reached 116 on October 11, 2024
with middle latitude AP of 123. In the past two issues this summary had
anticipated this seismicity and geomagnetic storm as:
These events occurred near local solar midnight and were probably promoted
by strong tidal stresses with today's new moon which maximized near this hour.
This summary had expected enhanced seismicity with this super-moon in previous
issues of this summary as:
"While global seismicity today was at relative moderate levels, several factors
in the next three days will probably move to enhance to possibility of
significant seismicity at the end of 2024. The first of these is the occurrence
of a super-moon on December 30,, 2024 as reported in earlier issues of this summary:
"The new moon will arrive on December 30, 2024. This is a super moon - nearer than normal for new moons.
This summary notes the likely influence on global seismicity of these increased
tides as:
The new moon (supermoon) will arrive on December 30, 2024 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland and the Atlantic Ridge while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/New Zealand and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this new moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this new moon are considered moderate to high in the next week (December 28-31, 2024 and January 1-4, 2025)." (December 27-29, 2024)
The activity in Coquimbo, Chile may have been triggered by SFE associated
with a strong X-class solar flare (X1.2 preliminary). It occurred at the
tail end of this flare near local solar midnight, both factors likely to
help trigger seismicity." (December 31, 2024)
The history of seismic activity in the Geysers area of California had been
summarized in this summary when a series of events in the Geysers region followed the M 7.0 off
the coast of Northern California on December 5, 2024 as:
A series of moderate earthquake in the Geysers area of northern California
followed the M 7.0 off the California coast. They were likely triggered
by P- and/or S-waves from that earthquake. This series included events of M 2.5 and 4.3.
NEIC reported these were felt with intensity up to III in northern and Central
California at Felton, San Jose, Santa Rosa, Yuba City, Rohnert Park and Fremont.
The last earthquake in the Geysers area of California with M>=4.3 occurred
September 7, 2024 with M 4.3, the last of larger magnitude was an M 4.5 on June 8, 2024.
At the time this summary noted:
"The strongest earthquake in the U.S. or Canada today was an M 4.5 in Northern California. NEIC reported it was felt with maximum intensity V in the Geysers, California.
This earthquake occurred within minutes of local solar noon and was probably promoted by strong tidal stresses which maximize near this hour.
EMSC reported strong shaking in Middletown, California. The last earthquaek in the Geysers area
of Northern California with M>=4.5 occurred on June 3, 2023 more than a year ago with
M 4.5. The last event in the area of larger magnitude occurred as an M 5.0 on December 14, 2016.
"The strongest earthquake in the U.S. or Canada today was an M 4.5 in the Geysers region of Northern California. NEIC reported it was felt with maximum intensity IV in Kelseyville and Middletown with intensity II-III in Geyserville, Healdsburg, Hidden Valley Lake, Cloverdale, Lower Lake, Calistoga, Windsor and as far to the south as San Francisco, California.
This is an area where fluid flow often controls seismicity. Strong tidal stresses
can be an effective means to move fluids. So it is not surprising that this
earthquake occurred in conjunction with today's full moon
...
Today's earthquake is the strongest event in the Geysers area since an M 5.0 on December 14, 2016.
That earthquake was likely the strongest recorded in the Geysers region of California as reported at the time in
this summary:
"While smaller earthquakes in the Geysers, California are nearly continuous, events
of larger magnitude are uncommon. Today's earthquake may be the largest ever
recorded in the Geysers area, in fact. An M 5.0 was recorded on May 7, 1955 but
magnitudes were not well determined at the time. No other events in the Geysers
area have reached M>=5.0 until today." (December 14, 2016, June 8, 2024, December 6, 2024)
The earthquake in California was preceded several hours earlier by an M 3.0 in
northwestern Nebraska. This earthquake occurred near local solar noon and was felt with intensity III
in Nebraska at Halsey, Mullen, Valentine and II in Omaha dn Wood Lake and possibly in Iowa.
This pattern of an unusual quake in Nebraska or South Dakota followed by a significant quake along the North America-Pacific plate boundary has been previously documented in this summary, for example before the M 7.0 off northern California on December 5, 2024 as:
"... Some interesting foreshock activity had been noted before the
M 7.0 off northern California. For example an M 2.8 in Nebraska had been
cited as a possible precursor to such an event as:
"Unusual light earthquakes occurred today in the U.S. and were felt in Massachusetts (M about 2.3)
near Worchester, MA and in Nebraska near Houston (M 2.8). Light seismicity in these areas often
precedes strongly enhanced seismicity along the Pacific-North American plate boundary
by hours to days. Increased seismicity along this boundary may be anticipated
in the next several days including a slight possibility of a moderate to large
regional event." (November 21, 2024, December 8, 2024)
A series of earthquakes about 100 km south of today's epicenter last occurred
in 2018. The last of these of M>=3 was an M 3.0 on December 13, 2018 but
the largest was an M 4,2 on June 30, 2018. At the time this summary noted:
"The most unusual and largest earthquake in the U.S. or Canada outside Hawaii today was an M 4.2 in Nebraska.
NEIC reported it was felt with intensity IV in Nebraska at Arnold and North Platte and II-III in Callaway, Stapleton, Brady. Earthquakes
in this area often precede by hours to days moderate to strong earthquakes along
the western rim of the North American Plate. These are usually in the region
of Alaska but can occur as far south as California." (June 30, 2018)
The strongest earthquakes in the world today occurred in the southern oceans.
These included an M 6.1 in the South Sandwich Islands and an M 5.5 in the
Balleny Islands south of New Zealand and an M 5.2 in the Tristan da Cunha area of the
South Atlantic. None of these were reported felt
in their remote epicentral areas. The event in the South Sandwich Islands occurred
within a few minutes of local solar noon and was probably promoted by strong
tidal stresses associated with the super new moon of December 30 as noted
in this and previous issues of this summary.
"The new moon (supermoon) will arrive on December 30, 2024 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland and the Atlantic Ridge while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/New Zealand and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this new moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this new moon are considered moderate to high in the next week (December 28-31, 2024 and January 1-4, 2025)." (December 27, 2024 to January 2, 2025)
The earthquake of M 6.1 in the South Sandwich Islands is at 102 degrees from
the M 7.4 in Vanuatu of December 17, 2024 (shadow zone boundary and node 7)
and was probably promoted by energy from that source. Likewise the M 5.2 in
the Tristan da Cunha area of the south Atlantic is at the third node (120 degrees)
from Vanuatu and was also a likely FFA from that event. An M 5.1 today in the Easter
Island area of the South Pacific is at the ninth node (80 degrees) from both
the M 7.0 in Northern California and from Vanuatu and may be a case of overlapping triggering
at the same distance like as is being observed in Ethiopia in the current swarm there.
The last earthquake of M>=6.1 in the South Sandwich Islands occurred as an M 6.3 on October 25, 2022. A great M 8.1 hit the
region on August 12, 2021. At the time of the event in 2022 this summary noted:
"The strongest earthquake in the world today was an M 6.3 in the area of the South Sandwich Islands, South Atlantic. It was not reported felt in this remote area.
It occurred near local solar midnight and may have been promoted by energy associated
with the solar eclipse and new moon today and/or by the strong mid-latitude geomagnetic
storm finishing up today. This area had been expected to see enhanced seismicity
with this new moon as noted in previous issues of this summary:
It is also likely to have been promoted by the geomagnetic storm at mid-latitudes
which continued today reaching A-index disturbance at mid-latitudes of 204, the
highest recorded by SWPC since at least 1994.
The last earthquake in the South Sandwich Islands within about 250 km of this
epicenter with M>=6.3 was an M 6.9 on August 16, 2021, itself an aftershock of
the M 7.5 of August 12, 2021. A more recent event of M 6.7 occurred on September 29, 2022
about 500 km southeast of this epicenter in the South Atlantic region." (October 25, 2022)
As well as being promoted by tidal and geomagnetic effects the area of
the South Sandwich Islands was also possibly triggered by SFE from Solar Flares
#2150 and 2170 (SWPC) which were coincident with this earthquake. An M 4.7
foreshock in the South Sandwich Islands about three hours earlier also
occurred at the maximum of solar flare 2110, suggesting the possibility
of a stronger regional event to follow. SWPC data for these flares follow:

The M 5.5 in the Balleny Islands which was not felt occurred 20 minutes after
the M 4.7 in the Geysers, California. It is located at 120 degrees (node 3)
from the California event and may have been promoted by energy from that source.
It, like the event of M 6.1 in the South Sandwich Islands today occurred near
local solar noon and may have been promoted by effects related to the new
moon of December 30, 2024 and/or the geomagnetic storm today both of which
maximize near local solar noon. The last earthquake within about 200 km of this
epicenter in the Balleny Islands of M>=5.5 occurred on November 15, 2024 with M 5.5
but the last with greater magnitude of M 6.0 on June 16, 2024 had been noted in this summary as:
"The strongest earthquake in the world today was an M 6.0 in the Balleny/Macquarie Island area
south of Australia and New Zealand. It was not felt in this remote area. This joines
a series of moderately large earthquakes along the Antarctic Ridge over the past
several days including a series to the east in the Pacific-Antarctic Ridge and the South Sandwich Islands (M 5.4) and
events south of Australia and on the Mid-Indian Ridge (M 5.8) today. These high latitude events suggest
a geomagnetic effect on their timing. Many of these occurred with a geomagneti storm
which today reached Planetary AP of 19 and 26 at high latitudes, the second strongest
geomagnetic storm of the past month (after June 7, 2024). This geomagnetic
storm is likely to continue for several more days and could bring enhanced
globals seismicity in this time period. The earthquake in the Macquarie Ridge is near-Antipodal to the continuing eruption
of volcanoes in southern Iceland and the two area are likely promoting regional
activity in these two regions. The relation between earthquakes in Macquarie
and Iceland has been noted in previous issues of this summary for example on March 5, 2024 as:
" ... Macquarie Island area around March 4, 2024. It is near the antipode
of the energetic volcanic eruption in southern Iceland and may have
been promoted by energy from that source." (March 5, 2024)
and on April 1, 2024 as:
"The strongest earthquake in the world today was an M 5.9 in the Balleny Islands
south of New Zealand. The epicenter of this unfelt earthquake is exactly
antipodal to the strong volcanic eruption in southern Iceland which has been
ongoing for several weeks. It is likely that today's earthquake in the Balleny Islands
was promoted by antipodal focusing of energy from the volcanic eruption in
Iceland. Compare the eruption coordinates (63N 24W) with the epicenter
of the M 5.9 in the Balleny Islands today (63S 156E) for antipodality.
The last earthquake in the Balleny Islands with M>=5.9 occurred on July 6, 2023
also in connection with a volcanic eruption in Iceland. At the time this
summary noted this relation as:
"The volcanic swarm of earthquakes in Iceland continued today near Reykjavik where many of the moderate quakes in this swarm were felt today.
A volcanic warning has been issued by Icelandic authorites as more than 2000
light to moderate quakes have occurred in this region in the past two days.
...
NEIC reported these earthquake of M 4.2-4.5 in Iceland was felt with intensity II-III in the area(s) of Iceland in Keflavik, Suournes.
The antipode of today's activity in Iceland is in the Balleny Islands south
of Australia and New Zealand at 63S 156E. Some enhanced seismicity in
this area is likely with the swarm in Iceland.
...
The strongest earthquake of the day occurred near the antipode of the tremors in Iceland.
This event of M 5.9 in the Balleny Islands was not reported felt in this remote epicentral area.
This event occurred simultaneously with Solar Flare 7970, the strongest solar
of the day and was probably promoted by Solar Flare Effects (SFE) associated
with that flare." (July 6, 2023)
Also on January 11, 2024, a strong volcanic eruption in Iceland was related
in this summary to the Balleny Islands as:
"An earthquake of M 4.5 occurred today in northeastern Iceland. NEIC reported it was felt with intensity up to VI in Hofn, Iceland.
This follows a pair of antipodal earthquake in the Balleny Islands two day ago.
At the time this summary noted in this regard:
"A series of moderate to strong earthquakes hit today at epicenters which
were the antipodes of active volcanism. The strongest of these was an M
5.6-6.0 in the Balleny Islands south of New Zealand. This is exactly
opposite on the earth to Iceland where volcanism has been active over the
past several weeks and months.
...
The earthquake in the Balleny Islands was the strongest in that region
in at least three years. A smaller M 5.5 hit the area on June 27, 2011.
The last earthquakes of similar or larger magnitude in the region occurred
on April 12, and April 16, 2007 with M 6.0 and 5.8.
The Balleny Islands are a remote sparsely populated region and today's
earthquake was not reported felt in the region. Followers of the P103 theory
may be interested to note that this epicenter is located at 103 degrees
from the mainshock in Japan of March 11. This suggest that some triggering
is possible at this distance from great earthquake because seismic energy
is concentrated at the surface at this distance." (July 21, 2011)
It is important to note that this summary written nearly 13 years ago is completely
congrueous with the current situation following a major quake in Japan at
103 degrees and a major eruption near the antipode in Iceland." (January 8, 2024)
The earthquake in Iceland was the beginning of a new eruption. Bubbling lava
could be seen on video on the web. Another area where a volcanic eruption
is occurring is in Mount Lewotobi Laki-Laki in Indonesia. This volcano is on Flores
Island. Thousands have been evacuated following several days of eruption
in this area." (January 11, 2024, April 1, 2024, June 16, 2024)
Today's earthquake in the Balleny Islands is at the third node (120 degrees) from the
M 7.0 off Northern California of December 5, 2024 and at the eighth node (45 degrees)
from the M 7.4 in Vanuatu of December 17, 2024 and may be FFA from both
these events.
The eruption in Iceland continued unabated today. It is at the antipode of
the M 5.5 in the Balleny Island region.
The series of moderate eathquakes in Awash, Ethiopia continued today. Today's earthquakes
with magnitude of M 4.2, M 5.1, 4.9, 4.6, and M 4.6 among others have been occurring throughout the past week and are
being felt with intensity III in Addis Ababa, and IV in Asbe Teferi Oromia, Ethiopia.
NEIC reported an earthquake of M 4.8 in Eastern China was felt with intensity up to V in the area(s) of Eastern China at Yinchuan, Ningxia.
NEIC reported an earthquake of M 3.1 in Hawaii was felt with intensity up to III in the area(s) of Hawaii at Naalehu and II in Captain Cook and Laupahoehoe.
NEIC reported an earthquake of M 2.7 in Southern California was felt with intensity up to II in the area(s) of Southern California at Cathedral City.

HAPPY NEW YEAR TO ALL. Seems like the year 2024 ended on a quiet seismic note
despite the new moon and stormy conditions in the geomagnetic. Let us hope
this seismic quiet continues.
The strongest earthquake in the world today was an M 5.6 in southern Vanuatu and the Loyalty Islands. NEIC did not report this earthquake was felt. It does not
appear to be an aftershock of the M 7.4 in Vanuatu of December 17 as it occurred
nearly 300 km south of that earlier epicenter. An earlier Vanuatu earthquake of M 4.8 (which was an aftershock
of the December 17 event) occurred today with M 4.4. NEIC reported this earthquake was felt with intensity III in Vila Shefa, Vanuatu.
The series of moderate eathquakes in Awash, Ethiopia continued today. Today's earthquakes
with magnitude of M 4.4, M 4.4, 4.3, 4.3, and M 4.8 among others have been occurring throughout the past week and are
being felt with intensity III in Addis Ababa, and IV in Asbe Teferi Oromia, Ethiopia.
The strongest earthquake in the U.S. or Canada today was an M 4.2 in the Fox Islands, Alaska. NEIC reported it was felt with intensity III in Nikolski, Alaska.
Geoscientists are warning that one of a series of underwater volcanoes west of
Oregon may be closing on a strong eruption. Data suggests swelling is occurring
in this area - a likely sign that magma is collecting and may soon reach the
explosive stress levels needed to break out in an underwater eruption.
A moderate M 5.1 earthquakes occurred in northern Chile in Tarapaca today.
GUC reported it was felt with intensity IV in Tarapaca at Pica; III in Iquique, Alto Hospicio, Camina, Huara, Pisagua, Chile.
GUC reported the following parameters for this event:
31-12-2024 23:13 20.1S 70.6W 22 5.1 IV Northern Chile
An earthquake of M 5.1 was felt in South Island, New Zealand today.
GEONET reported it was felt with light to moderate intensity in the area southeast of Picton, New Zealand and in southern North Island and northern South Island. 13 reports of felt events were made of which 1 reported weak and 0 light intensity with 0 report of moderate shaking and 0 with strong and 0 severe and 0 with extreme intensity came from the area.
Following are the parameters from GEONET for this event:

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

Two earthquakes of M 5.5 each were located within about a minute today in the
area of Coquimbo, Chile. These were followed by a continuing series of moderate
aftershocks and may lead to a stronger regional event. NEIC reported they were felt with intensity IV in La Serena, Coquimbo and Vicuna.
EMSC reported moderate shaking in La Serena, Paiguano and Valparaiso.
These events occurred near local solar midnight and were probably promoted
by strong tidal stresses with today's new moon which maximized near this hour.
This summary had expected enhanced seismicity with this super-moon in previous
issues of this summary as:
"While global seismicity today was at relative moderate levels, several factors
in the next three days will probably move to enhance to possibility of
significant seismicity at the end of 2024. The first of these is the occurrence
of a super-moon on December 30,, 2024 as reported in earlier issues of this summary:
"The new moon will arrive on December 30, 2024. This is a super moon - nearer than normal for new moons.
This summary notes the likely influence on global seismicity of these increased
tides as:
The new moon (supermoon) will arrive on December 30, 2024 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland and the Atlantic Ridge while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/New Zealand and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this new moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this new moon are considered moderate to high in the next week (December 28-31, 2024 and January 1-4, 2025)." (December 27-29, 2024)
The activity in Coquimbo, Chile may have been triggered by SFE associated
with a strong X-class solar flare (X1.2 preliminary). It occurred at the
tail end of this flare near local solar midnight, both factors likely to
help trigger seismicity. Other activity associated with this flare included
a foreshock in Luzon, Philippines of M 3.1; and M 4.4 in Ethiopia and an M 4.2 in Costa Rica.

A moderate earthquake of M 5.5 also shook the northern region of Luzon, Philippines today. NEIC reported maximum intensity VI in Ilocos, Philippines at Pagudpud; V at Badoc, Fuerte, Laoag and San Nicolas; IV in Tuguegarao and in the Cordillera at Tuding and La Trinidad and II in Bantay, Batac and Pudoc, Ilocos.
This earthquake is located at the sixth node (60 degrees) from the Vanuatu
earthquake of M 7.4 of December 17 and is probably an FFA of that event.
Small foreshocks hit this region yesterday and were noted in this summary
at the time as:
"The M 4.0 in Luzon, Philippines occurred shortly after this flare. This
area of the Philippines has been active since the M 7.4 in Vanuatu of December 17
as noted in previous issues of this summary and could see further moderate
to strong activity in the next several days with the new moon. This summary
noted the seismicity of this area recently as:
"An earthquake of M 5.0 in northern Mindanao - felt in Dumaguete City, Philippines
was probably also promoted by FFA from both Vanuatu (52 degrees - node 7) and
Northern California (103 degrees). NEIC reported it was felt in the Central
Visayas, Philippines with maximum intensity VI ini Bayawan; III in Dumaguete, Janiuay and II in Boljoon, Sibulan and Siquijor.

December 29, 2024
The strongest earthquake in the world today was an M 5.5 in the area of Houma, Tonga. This deep focus event may have been felt lightly in the epicentral area.
This event may have been promoted by the passage of Tropical Cyclone over this epicenter today as noted in this summary:
TC Six continued today in Tonga with winds up to 45 kts It may enhance seismicity in the region of Tonga December 28-30.
This earthquake in Fiji may also have been promoted by a moderately strong
solar flare (SWPC #480) - a C8.6-class event as it occurred near the maximum
of that flare. Data from SWPC for this flare follows:

Luzon M 4.0, 21:34 UT
Fiji M 5.5 19:57 UT
The M 4.0 in Luzon, Philippines occurred shortly after this flare. This
area of the Philippines has been active since the M 7.4 in Vanuatu of December 17
as noted in previous issues of this summary and could see further moderate
to strong activity in the next several days with the new moon. This summary
noted the seismicity of this area recently as:
"An earthquake of M 5.0 in northern Mindanao - felt in Dumaguete City, Philippines
was probably also promoted by FFA from both Vanuatu (52 degrees - node 7) and
Northern California (103 degrees). NEIC reported it was felt in the Central
Visayas, Philippines with maximum intensity VI ini Bayawan; III in Dumaguete, Janiuay and II in Boljoon, Sibulan and Siquijor.
PHIVOLCS reported it with intensity V in Hinoba-an, Negros Occidental and III in San Jose de Buenavista and Hamtic, Antique; City of Iloilo; City of Sipalay, Negros Occidental and II in Sibulan, Negros Oriental, Philippines." (December 21, 2024)
Several other moderate earthquakes at nodal distances from Vanuatu and from
the M 7.0 in Northern California of December 5, 2024 also occurred today.
An M 5.3 in the South Atlantic area occurred at 144 degrees from Northern
California - a distance at which strong FFA triggering has been observed
and noted in previous issues of this summary.
An M 5.0 near the Central Mid-Atlantic was also located at 148 degrees from Vanuatu
earlier in the day.
In the December 10, 2024 issue it had been noted in this regard:
"An M 5.7 also occurred today in the South Indian Ocean Ridge. This was not
reported felt in the epicentral area. The last earthquake with M>=5.7 within
about 200 km of this epicenter was an M 5.7 on April 26, 2023 and an M 5.9 on October 2, 2021.
This event is located at 147 degrees from the M 7.0 in Northern California
of December 5, 2024 and was probably a far-field aftershock of that event.
An M 5.0 near the Central Mid-Atlantic was also located at 148 degrees from Vanuatu
earlier in the day.
The distance 142-148 degrees is where core reflections and refractions
return to the surface. Enhanced seismicity is often noted in this distance
range following major world=wide earthquakes as noted in this summary in
the previous issue:
"Outer shadow zone edge (141-148 degrees)
Coast of Northern California to Comores Islands,." December 5, 2024)
This indicates strong far-field triggering in the Indian Ocean at this time - triggering
which could include areas near the antipode of northern California to the
south of this event." (December 10, 2024)
A series of large ocean waves did considerable damage in Peru today causing many ports to be shut down.
Some sources on the internet described these as "tsunamis". They are not tsunamis as they were
not generated by a change in elevation of the sea floor. Rather they are
unusually large ocean waves generated by wind, temperatures, etc and do
not have their origins in tectonic motion. There were no true tsunamis today.
These generally require a major underwater earthquake to form.
The series of earthquake in Ethiopia continued today with a number of moderate earthquakes up to M 5.1 felt with intensity II-III in Ethiopia at Addis Ababa and Awash, Afar.
While global seismicity today was at relative moderate levels, several factors
in the next three days will probably move to enhance to possibility of
significant seismicity at the end of 2024. The first of these is the occurrence
of a super-moon on December 30,, 2024 as reported in earlier issues of this summary:
"The new moon will arrive on December 30, 2024. This is a super moon - nearer than normal for new moons.
This summary notes the likely influence on global seismicity of these increased
tides as:
The new moon (supermoon) will arrive on December 30, 2024 at 22:27 UT. Longitudes which are at local solar midnight at this time are located at about 20 East while those at local solar noon are near 160 West. In the east these include most of western Europe and Iceland and the Atlantic Ridge while in the west areas of the western Aleutians, Alaska, Hawaii, Tonga/Fiji/New Zealand and portions of the Pacific-Antarctic Ridge are included. These are the most likely areas to see significant tidal triggering with this new moon. Other areas may also see tidal promotion in the next week especially at times of large solar flares and near local solar midnight and solar noon. The likelihood of a strong associated earthquake with this new moon are considered moderate to high in the next week (December 28-31, 2024 and January 1-4, 2025)." (December 27-28, 2024)
A severe geomagnetic storm is expected to accompany this new moon, due in part
to a series of strong solar flares. Geomagnetic storms can help promote
seismicity in areas at local solar noon and midnight when the storms hit and
later due to SFE associated with flares. This is likely to enhance seismicity
especially near the IDL.
