EARTHQUAKES SHAKE CENTRAL PERU, SEA OF OKHOTSK, RUSSIA
EARTHQUAKE SUMMARY FOR JANUARY 20, 2021
The strongest earthquake in the world today was an M 5.5 in Central Peru. NEIC reported it was felt with maximum intensity VI in Ica Peru at Marcona and Palpa; V in Nazca, Santiago, Vista Alegre, and Pisco and IV in Los Aquijes, Acari, San Juan Bautista and San Clemente. Moderate foreshocks of M 4.8, 5.3 and M 5.1 shook Nazca with intensity III-IV. NEIC reported aftershocks of M 4.8 and M 5.3 in Central Peru were felt with intensity II-III in the area(s) of Central Peru at Vista Alegre, Ica. This activity was likely promoted by strong tidal stresses associated with the new moon of January 13 as it occurred at the longitude where such stresses were maximized at the time as noted in previous issues of this summary:
"The new moon will arrive at 05:00 UT on January 13. Longitudes which are at sub-lunar conditions (local solar midnight) at this time are near 75 West and those at sub-solar conditions (local solar noon) are near 105 East. These include in the west, the west coast of South America and eastern North America and in the east western and central Indonesia, the Philippines and Taiwan among others. These areas are most likely to see tidally enhanced seismicity in the next week through January 17, 2021. Tidal enhancement is most likely near local solar noon and midnight. A strong global earthquake is likely in this period." (January 12-18, 2021)
Forecasts 130475 and 130762 had expected today's activity between January 17 and 23 to the east of today's epicenter in Central Peru. An M 7.1 hit the region about 100 km southeast of today's epicenter on January 14, 2018 but the last event of M>=5.5 within about 200 km of today's epicenter occurred as an M 5.7 on December 27, 2020 and an M 5.6 on October 28, 2020. This activity is located at 144 degrees from the M 6.7 quake in Mongolia of January 11, 2021, the largest earthquake of the current year. Seismic energy is concentrated at this distance from major surface disturbances after reflection and refraction off core boundaries and can help promote further seismicity at this distance.

An M 5.5 in the Sea of Okhotsk, Russia also occurred today. NEIC reported it was felt with intensity V in Toyohara, Sakhalin, Russia. This deep focus earthquake (575 km depth) is the strongest in the Sea of Okhotsk within about 300 km of this epicenter since an M 6.0 on November 2, 2018; an M 5.7 on July 23, 2016 and an M 5.5 on November 23, 2005. The largest, and only event in the region with M>6 in the past 30 years was an M 7.3 on November 17, 2002. Forecast 130446 had expected today's event within about 35 km of this epicenter was likely around January 20.

An unusual earthquake of M 4.2 shook central Austria today.
NEIC reported this earthquake of M 4.1-4.2 in Austria was felt with intensity IV in the area(s) of Liezen, Austria and II-III in Austria at Hall Tirol, Micheldorf, Fohnsdorf, Sankt Valentin, Sahladming, Steiermark, Tamsweg, Salzburg, Linz, Linz, Oberosterreich, and in Budweis, Jihocesky, Czech Republic.
The only event of M>=4 in the past year in Austria was an M 4.0 on August 8, 2020. The last earthquake in Austria within about 150 km of today's epicenter with M>=4.3 occurred as an M 4.4 on October 1, 2004. The only event within this area in the past 8 years within Austria and within about 200 km of today's epicenter was an M 4.3 on December 3, 2012. Forecast 130382 had expected today's event was likely in mid-January in Austria.

An M 3.3-3.5 in the greater Los Angeles, California area today was reported by NEIC to have been felt with maximum intensity IV in Los Angeles and Compton, California. Moderate earthquakes in this area of Los Angeles have been absent within about 75 km of this epicenter since an M 4.5 on September 19, 2020 and an M 4.2 on July 30, 2020. Forecast 130671 had expected today's event within about 10 km was likely around January 23.

An unusually large earthquake of M 5.2 occurred in the Gulf of California, Mexico today. It followed an M 4.2 which was probably promoted by strong tidal stresses as it occurred within about 30 minutes of local solar midnight, a time when such stresses maximize. The M 5.2 is the strongest event within about 150 km of its epicenter since an M 5.3 on September 24, 2020 and prior to that an M 6.3 on January 19, 2018. Forecast 130302 had expected today's activity in this region was possible around January 19. Earthquakes in the Gulf of California can add stress to faults to the north in California promoting further seismicity in that region. The M 3.5 in Los Angeles, California today occurred about 1.5 hours after the M 5.2 in the Gulf of California and may have been enhanced from that event. Both these events in the Gulf of California and the M 3.5 in Los Angeles, California today are at 102-104 degrees from the M 7.0 in the Dodecanese Islands, Greece of October 30 and were probably enhanced by concentrated energy from that source.

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 GAMMA RAY BURST ASSOCIATED WITH M 6.5 IN ARGENTINA
EARTHQUAKE SUMMARY FOR JANUARY 19, 2021
Moderate aftershocks continued to be felt in the San Juan, Argentina area today.
The strong, damaging earthquake in San Juan, Argentina early on the morning of January 19, 2021 was probably promoted by effects from a strong GRB, the first since January 12. This GRB was first observed within about 10 minutes of the earthquake in Argentina (02:54 UT vs 02:46 UT) as noted in the EXTERNAL FIELDS section of this report with the following preliminary SWIFT parameters:
"The last major Gamma Ray Burst (GRB) according to the online NASA Swift GRB Catalog was observed on January 19, 2021 at 02:54 UT with BAT Fluence n/a erg/sqcm. (MAGNITUDE: n/a), Associated earthquake: San Juan Argentina 02:46 UT M 6.4)" (January 19, 2021)
This summary noted in regard to the Argentina event earlier today:
"No major damage was reported. The only similar earthquake in San Juan, Argentina with M>=6.4 in the past 30 years was an M 6.4 on November 20, 2016. That event occurred at an intermediate depth of 116 km but today's event at 5-10 km depth is an unusual shallow focus. The last such event at shallow focus of M>=6 within about 250 km of today's events was an M 6.0 on February 27, 2010, the only such event in the region in the past 30 years. Today's event which occurred near local midnight (at 23:50) was probably promoted by strong tidal stresses associated with the new moon of January 13" (January 18-19, 2021)

The strongest earthquake in the U.S. or Canada today was an M 3.8 in the Alaska Peninsula aftershock zone. The last earthquake within about 100 km of this epicenter with M >=3.8 was an M 4.7 on December 25, 2020 but more recent events of similar magnitude have occurred on January 4 (M 3.5) and January 14 (M 3.7). Forecast 130430 had expected today's activity was likely around January 17.

An M 3.6 in the Mayotte Region north of Madagascar today renewed seismicity in that region. A similar M 3.6-3.7 quake hit the region on January 13, 2021, the such event in the past two months since an M 3.9 on November 22, an M 4.8 on November 10 and an M 4.5 on September 25, 2020. Throughout the first eight months of 2020 Mayotte was active with a moderate event nearly every week. Today's earthquake occurred as Tropical Storm Eloise made landfall in the area and had been expected in this summary as a possible consequence of that landfall as:
"Tropical Cyclone Eloise continued today east of Madagascar with winds up to 65 kts. It is expected to track to the east over the next several days possibly enhancing seismicity in the Mayotte area." (January 18-19, 2021)
Forecast 130478 had expected today's event in the Mayotte or Madagascar area in mid-January. This epicenter is at 104 degrees from the Los Lagos, Chile M 6.7 of December 27, 2020 and may have been promoted by energy from that source. Earthquakes in Vancouver, Canada were at a similar distance from Los Lagos.

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 SHAKES CHILE AND ARGENTINA
EARTHQUAKE SUMMARY FOR JANUARY 18, 2021
A strong M 6.4-6.8 earthquake was widely felt in Chile and Argentina today. It was reported by NEIC to have been felt with maximum intensity VI in Argentina at San Juan; V in San Martin, Mendoza and IV in Mendoza. In Chile it was reported with V in Llaillay, Valparaiso; IV in Valparaiso at San Felipe, La Ligua, Calera and in Santiago with lesser shaking of III in Los Andes, Cabildo, Valparaiso. GUC reported it at M 6.5 and that it was felt with intensity V in Coquimbo at Illapel, Paiguano, Vicuna; IV in Salamanca, Monte Patria, La Serena, Combarbala, III in Andocollo, Coquimbo, La Higuera, Ovalle, Rio Hurtado and II in Canela, Los Vilos, in Atacama with IV in Alto del Carmen; III in Copiaopo, Freirina, Tierra Amarilla, Vallenar and II in Huasco; in Valparaiso with V in La Lgua, Quilpue, Valparaiso, Zapallar; IV in Catemu, El Tabo, San Antonio, San Felipe, Santa Maria, Villa Alemana and III in Casablanca; in Santiago with V in Macul, Melipilla, and San Jose de Maipo; IV in El Bosque, Las Condes, Pedro Aguirre Cerda, Penalolen, Providencia, Pudahuel, Quinto Normal and III in La Florida, Maipu, Santiago and II in Puente Alto and Recoleta; in O'Higgins with IV in Mostazal, Rancagua and III in Chepica, Lolol, Peumo, Santa Cruz and in Maule with III in Curico, Rauco and II in Pencahue and Sagrada Familia, Chile. No major damage to people or services was reported by GUC. No tsunami was reported. Aftershocks of M 5.3, 4.8 and 4.9 were also felt in the area. Authorities in the area reported no injuries but damage impacted streets and highways in San Juan.
Some locations saw power cuts and damage occurred to homes in the town of Caucete with others evacuated in Zonda, San Juan. No major damage was reported. The only similar earthquake in San Juan, Argentina with M>=6.4 in the past 30 years was an M 6.4 on November 20, 2016. That event occurred at an intermediate depth of 116 km but today's event at 5-10 km depth is an unusual shallow focus. The last such event at shallow focus of M>=6 within about 250 km of today's events was an M 6.0 on February 27, 2010, the only such event in the region in the past 30 years. Today's event which occurred near local midnight (at 23:50) was probably promoted by strong tidal stresses associated with the new moon of January 13 as reported in the forecast for tidal triggering with that alignment in previous issues as:
"The new moon will arrive at 05:00 UT on January 13. Longitudes which are at sub-lunar conditions (local solar midnight) at this time are near 75 West and those at sub-solar conditions (local solar noon) are near 105 East. These include in the west, the west coast of South America and eastern North America and in the east western and central Indonesia, the Philippines and Taiwan among others. These areas are most likely to see tidally enhanced seismicity in the next week through January 17, 2021. Tidal enhancement is most likely near local solar noon and midnight. A strong global earthquake is likely in this period." (January 8-12, 2021)
An M 4.4 to the west occurred several hours earlier and was reported with maximum intensity IV in Santiago and Coquimbo, Chile and III in San Felipe and Lampa, Chile and III in Mendoza, Argentina. A moderate foreshock hit the same area of Argentina on January 16, 2021. This event of M 4.9 - also near local solar midnight. A larger M 6.1 occurred in Jujuy, Argentina on January 10, 2021 near local solar midnight and was reported here at the time as:
"The M 6.1 in northern Argentina was reported by NEIC to have been felt with intensity VI in Salta, Argentina; IV in Antofagasta, Chile and II in Iquique, Tarapaca, Chile. It was preceded by an M 4.5 foreshock that was felt with intensity III in Antofagasta. GUC reported this earthquake was felt with intensity IV in Antofagasta at Antofagasta, Calams, Mejillones and III in Taltal, Tocopilla; in Tarapaca with III in Iquique and II in El Loa, La Tirana, Pica, Pozo Almonte; and in Atacama with IV in Chararal, Diego de Almagro, El Salvador and III in Copiapo and Tierra Amarillo, Chile. This is the strongest earthquake within about 250 km of this epicenter since an M 6.3 on November 20, 2020 and prior to that an M 6.3 on April 15, 2017. ... The quake occurred within about 30 minutes of local solar midnight and may have been enhanced by strong tidal stresses which are maximized at this hour. Maximum stress with the next full moon on January 13 is near this longitude as noted in the tidal forecast" (January 10-11, 2021)
Forecast 130507 had expected seismic activation in mid-January about 150 km west of today's epicenter was likely.

Another M 4.4 occurred earlier in the day in the Yellow Sea of China near South Korea. It was reported felt in South Korea at Taech on Chungchongnam, Mokpo, Cholianam, Haenam, Onyang, Suigen Kyonggi, Seoul, Hwado, Gumi, Changsungoo and Gyeongju with intensity III-IV. This epicenter is in the antipodal area of the later M 6.4 in Argentina. This is the strongest earthquake within about 250 km of this epicenter near South Korea since an M 4.8 near this epicenter on April 20, 2013. Forecast 130400 had expected activation in this area to the northeast around January 20.

The strongest activity in the U.S. or Canada today occurred in the region of the Alaska Peninsula with M 4.0 and 3.9. These are not uncommon events in this region of aftershocks of the M 76. of October 19, 2020 and were not reported felt in this area. They had been expected at this time in forecasts 130430 and 130457.

The most widely felt earthquake in the U.S. today was an M 2.7 north of San Francisco. NEIC reported this earthquake of M 2.7 north of San Francisco, California was felt with intensity II-III in the area(s) north of San Francisco, California in Santa Rosa, Fulton, Windsor, Rohnert Park and Sebastopol. This appears to be part of a regional activation of the past several days which now appears to be diminishing. Forecast 130328 had expected today's event around January 19.

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.

LIGHT SWARM AT MOUNT HOOD, OREGON MAY BE RELATED TO VOLCANIC EPISODE
EARTHQUAKE SUMMARY FOR JANUARY 17, 2021
A series of light to moderate earthquakes shook the area of Mount Hood, Oregon today. These were reported by NEIC to have been felt with maximum intensity V in Oregon at Hood River and I-III in Government Camp, Mount Hood Parkdale, The Dalles, Gresham, Portland, Oregon. The strongest of today's events in the Mount Hood area was M 2.8. These follow a strong swarm in the Mammoth Lakes area of California several days ago. A strong swarm in Mammoth Lakes in May, 1980 followed the eruption of Mt. St. Helens in Washington about a week later. Some relation between volcanic areas in Washington and Oregon and those in California is possible. The last earthquake of M>=2.8 in the Mount Hood area was an M 2.8 on October 10, 2017. The last of larger magnitude was an M 3.0 on May 14, 2010 and an M 3.3 on July 7, 2003. The strongest earthquake in the area in the past 30 years was an M 4.5 on June 29, 2002.
At the time of the June 29, 2002 event this summary noted:
"A strong swarm of earthquakes hit the Mt. Hood Oregon area this morning. This swarm included several Ml>=3 events and a Ml 4.5 earthquake which was the largest earthquake ever recorded in the Mt. Hood region. The previous largest had occurred on Dec. 13, 1974 (Ml 4.1)." (June 30, 2002)
"... most significant swarm since 2002 when more than 200 quakes - including a widely felt event of M 4.5 struck the mountain on June 29-30, 2002. Nearly 1400 quakes have hit the mountain in the past 30 years - about half of which have been in these swarms of unknown origin. Of these 180 have been of M>=2.
The first swarm in recent years occurred in July, 1980 two months after the eruption of Mt. St. Helens, 100 km away. A connection between the two swarms was considered at the time but a mechanism could not be determined for such a relation. Quakes increased from 1987 to 1994 and averaged about 15 a year. A second pulse of quakes started in 1998 and ended with the 2002 swarm.
The last eruption of Mt. Hood occurred 200 years ago. The 2002 swarm did not appear to have indicated new volcanic unrest." (June 30, 2002)
Forecast 130415 had expected today's event was likely at Mount Hood within
about 5 km of these epicenters around January 20. This activity is at the fifth node (72 degrees) from the M 6.7 in Mongolia of January 11, 2021 and may have been promoted by energy from that source.

A light earthquake of M 2.8 was felt in southeastern Maine today. NEIC reported it was felt with intensity II-III in Maine at Jonesboro, Columbia Falls, Jonesport, Harrington and Lebanon. This is the strongest earthquake within about 100 km of this epicenter since an M 3.5 on September 25, 2005. More recent quakes of this magnitude or larger slightly outside the 100 km distance as a series (M 2.8-3.2) to the west in late 2006 and an M 3.8 on January 10, 2019. An M 3.0 also occurred northeast of this epicenter on December 9, 2020. At the time this summary noted in this regard:
"An unusual earthquake of M 3.0 shook regions of south-central Maine today. NEIC reported it was felt with maximum intensity VI in Baileyville and II-III in Robbinston, Calais, Pembroke, Perry, Meddybemps, Baileyville and Whiting and in Saint Andrews, Saint Stephen, New Brunswick, Canada, This event followed a smaller M 2.4-2.7 two hours earlier which was also felt. The M 3.0 is the strongest within about 100 km of this epicenter since an M 3.8 to the east on January 10, 2019 and an M 3.3 on February 9, 2016." (December 10, 2020)
Forecast 130065 had expected enhanced seismicity within about 50 km of today's epicenter in mid-January.

The strongest earthquake in the U.S. or Canada today was an M 3.5 in the Mina, Nevada area. This continues elevated seismicity in the region as discussed in the previous issue of this summary. It was not reported felt. Forecast 130322 had expected this activity around January 18, 2021.

The strongest earthquake in the world today was an M 5.4 in the South Sandwich Islands of the South Atlantic. This area has been active in January, 2021 with an M 5.6 on January 4; an M 5.2 on January 8 and an M 5.4 on January 11, 2021.
In the past year most of the strong activity in the South Sandwich Islands has been in the southern section with an M 6.4 in July and an M 6.1 in February, 2020. Earthquakes in this area, like today's are seldom felt. Forecast 130526 had expected today's event was likely within about 100 km in mid-January. This earthquake is located at 104 degrees from the last major earthquake in the world - the M 7.0 in the Dodecanese Islands of October 30,, 2020 and may have been promoted by energy from that source. Other earthquakes at this distance from Greece today occurred in Oaxaca, Mexico, Ecuador, Baja California, Sumbawa, Indonesia and El Salvador.

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.

CENTRAL AND NORTHERN CALIFORNIA ACTIVE
EARTHQUAKE SUMMARY FOR JANUARY 16, 2021
The strongest earthquakes in the U.S. or Canada today were an M 4.2-4.4 off the coast of Central California and an M 4.4 off Northern California. These were accompanied by a series inland Central California including an M 4.0. These follow two events in central California of M>=3.6 in the past two days. These included the M 3.9 in the region of Mammoth Lakes yesterday and an M 3.6 north of San Francisco the day before. This suggests the area is somewhat unstable at this time, but may also indicate a longer term instability promoted by tidal stresses associated with the new moon of January 13, 2021. Strong to major earthquakes in the region generally occur in association with major solar or geomagnetic events. Earthquakes in this region off Central California have occasionally been followed by stronger earthquakes further to the east in the region of the San Andreas Fault zone. This activity is near 103 degrees from the M 7.0 in the Dodecanese Islands of M 7.0 of October 30, 2020, the last major earthquake in the world and was probably promoted by energy from that source.
NEIC reported the earthquake near Monterey Bay, Central California was felt with maximum intensity IV in California at Aromas, San Juan Bautista, Salinas, Watsonville, Castroville, Moss Landing, Gilroy. Aftershocks were also felt in the area. The last earthquakes of M>=4.4 within about 100 km of today's epicenter occurred on October 15, 2019 with M 4.5 north of San Francisco and an M 4.7 fourteen hours later near today's epicenter. The earthquake north of San Francisco this year occurred near the same location as in 2019 on January 14, 2021 at 19:18. Today's earthquake of M 4.4 was expected in this region by forecast 130326 within this area.

An earthquake of M 4.4 also occurred off the coast of northern California today. It was reported by NEIC to have been felt lightly in Ferndale, McKinleyville, Crescent City and Willits. The last earthquake of M>=4.4 within about 75 km of this epicenter off northern California occurred on March 9, 2020 with M 5.8 and an aftershock of M 4.9 3.5 hours later. An M 4.4 also hit the region on March 24, 2019. Forecast 130409 had expected today's event was likely within about 30 km of this epicenter around January 16. This event occurred near local solar midnight and may have been promoted by tidal stresses.

A series of light earthquakes in the East Tulare County area of Central California also occurred earlier in the day. This event is to the east near the Nevada border. NEIC reported it was felt with intensity II-III in East Tulare County, Lone Pine, Springville, Inyokern, Kernville, Onyx, Three Rivers, Lake Isabella, Porterville, and Wofford Heights. Associated shocks of M 3.2 and 3.8 followed and were lightly felt in the area. An M 5.5 hit east of this on June 4, 2020 and was followed by an M 4.2 about an hour later within about 25 km of today's epicenter. A second M 4.2 hit this area to the north by about 30 km on September 11, 2020, the last such event in this region. Forecast 130319 had expected today's event within about 30 km was likely around January 14.

The strongest earthquake in the world today occurred in Hindu Kush, Afghanistan with M 5.5. NEIC reported it was felt with intensity V in Afghanistan at Faizabad and IV in Handud, Kabul, Mardan, Pakistan, Dushanbe and Navabadski, Tajikistan, and with lesser intenstiy in Peshawar and Mingaora, Pakistan, Nurak, Tajikistan and Mahmoud Raqui, Afghanistan. This is the strongest earthquake in Afghanistan since an M 5.6 on June 16, 2020 and prior to that
an M 6.1 on December 20, 2019. Forecast 130336 had expected today's earthquake within about 50 km was likely around January 20, 2021.

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 EARTHQUAKE OFF SOUTHERN GUATEMALA
EARTHQUAKE SUMMARY FOR JANUARY 15, 2021
The strongest earthquake in the world today was an M 5.9 off the coast of Guatemala. NEIC reported it was felt with maximum intensity VII in Champerico, Retalhuleu, Guatemala d IV in Quetzaltenango with lesser shaking in Chimaltenango, Sacatepequez, Itzapa, and Escuintla. The mainshock was followed by several aftershocks including an M 4.9 felt with intensity III in Santa Catarina Pinula, Guatemala. This may have been promoted by high tidal stresses associated with the new moon as noted in previous issues of this summary:
"The new moon will arrive at 05:00 UT on January 13. Longitudes which are at sub-lunar conditions (local solar midnight) at this time are near 75 West and those at sub-solar conditions (local solar noon) are near 105 East. These include in the west, the west coast of South America and eastern North America and in the east western and central Indonesia, the Philippines and Taiwan among others. These areas are most likely to see tidally enhanced seismicity in the next week through January 17, 2021. Tidal enhancement is most likely near local solar noon and midnight. A strong global earthquake is likely in this period." (January 8-12, 2021)
This is the largest earthquake in the region of Guatemala in the past year - an
M 5.8 occurred near this epicenter on August 4, 2020. The last earthquake in the area of M>5.9 was an M 6.6 on February 1, 2019 and prior to that an M 6.1 on October 28, 2018. Forecast 130274 had expected today's activity in Guatemala was likely around January 17. This earthquake activity is located at 103 degrees from the M 7.0 in the Dodecanese Islands, Greece of October 30, 2020 - the last major earthquake in the world. It was likely promoted by concentrated energy from that source. A series of moderate earthquakes at this distance from Greece also occurred today in Ecuador today, and were probably also promoted by tidal stresses and by energy from the Dodecanese Islands.

A moderate earthquake of M 5.5 was also widely felt in southern Iran today. NEIC reported it was felt with maximum intensity V in Bandar-e Langeh, HJormozgan, Iran and IV and III in the United Arab Emirates and at Dona, Qatar. This is the strongest earthquake in Southern Iran within about 250 km of this epicenter since an M 5.8 and 5.5 on June 9, 2020. Forecasts 129973 and 130312 had expected today's event within about 100 km was likely in mid-January.

A series of light earthquakes occurred in the Mammoth Lakes, California area today. The largest of these included an M 3.9 and were felt with intensity II-III in Bishop, June Lake, Benton, California. While a series of events have occurred about 50 km north of today's epicenter in Nevada starting with an M 5.2 on April 11, 2020, this is the strongest event in the Mammoth Lakes area since an M 4.1 on April 5, 2020. Forecast 130320 had expected today's event in this area was likely around January 15. Like activity in Guatemala and Ecuador, this is located near 100 degrees from the Dodecanese Islands and was probably promoted from that source.

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 EARTHQUAKE IN SULAWESI, INDONESIA
EARTHQUAKE SUMMARY FOR JANUARY 14, 2021
The strongest earthquake in the world today was an M 6.2 in Sulawesi, Indonesia. NEIC reported it was felt with damage in Sulawesi at Majene and Polewali with lesser shaking at Palu and Dengasar, Bali, Indonesia. BMG reported intensity IV-V in Majene; III in Palu and II in Makasar, Sulawesi, Indonesia. This follows a foreshock of M 5.7 which hit the area yesterday and was noted in this summary in the previous issue as:
"The strongest earthquake in the world today was an M 5.7 in Sulawesi, Indonesia. It was not reported felt in this area but was probably felt lightly in the epicentral area. This event occurred within about an hour of local solar noon and was probably enhanced by tidal stresses associated with the new moon as noted in previous issues of this summary:
"The new moon will arrive at 05:00 UT on January 13. Longitudes which are at sub-lunar conditions (local solar midnight) at this time are near 75 West and those at sub-solar conditions (local solar noon) are near 105 East. These include in the west, the west coast of South America and eastern North America and in the east western and central Indonesia, the Philippines and Taiwan among others. These areas are most likely to see tidally enhanced seismicity in the next week through January 17, 2021. Tidal enhancement is most likely near local solar noon and midnight. A strong global earthquake is likely in this period." (January 8-12, 2021)
It is also located near the geomagnetic equator and may have been promoted by the geomagnetic storm two days ago. Forecast 130260 had expected today's event within about 200 km of this epicenter was likely around January 16. This area often sees a series of moderate to large earthquakes and more such activity may be seen in the next several days. This epicenter is at the seventh node (51-52 degrees) from the M 6.7 in Mongolia of January 11 and may have been promoted by energy from that source." (January 13-14, 2021)
Like the M 5.7 foreshock, the M 6.2 was also probably promoted by high tidal stresses as it occurred near local solar midnight. The last earthquake within about 300 km of today's event of equal or greater magnitude was an M 7.5 on September 28, 2018 about 300 km northeast of today's epicenter. The last within about 250 km was an M 6.3 on August 18, 2012 and prior to that an M 6.3 on January 23, 2005, the largest events in this area in the past 30 years. Forecast 130260 had expected today's event in this area was likely around January 16.

The most widely felt earthquake in the U.S. today was an M 3.6 in the San Francisco Bay area of California. NEIC reported it was felt with intensity III in Concord, Pleasant Hill, Walnut Creek, Lafayette and Martinez, California among many other communities within about 150 km of the epicenter. This is the strongest earthquake within about 100 km of this epicenter in the San Francisco Bay area since an M 4.3 on July 16, 2019. Forecast 130327 had expected this earthquake was likely around January 12 within about 10 km of the epicenter. The M 3.6 occurred within about 45 minutes of local solar noon, a time when tidal stresses are maximized and may have been promoted by those stresses which are high with the new moon.

The strongest earthquake in the U.S. or Canada today was an M 4.0-4.7 in Hawaii. NEIC reported it was felt with intensity V in Pahala and IV in Captain Cook and II-III in Hawaii National Park, Naalehu, Volcano, Pahoa, Mountain View, Hilo and Holualoa and Kurtistown. This is part of the continuing eruption of Kilauea Volcano on Hawaii but is the strongest event in the region since the current eruption began. An M 4.7 hit north of this on July 27, 2020 but the last in the area of Kilauea was an M 5.3 on March 13, 2019 and at the end of the previous eruption on August 2, 2018. Forecast 130276 had expected a moderate quake in Hawaii was likely in mid-January.

The last earthquake with M>=2.9 within about 100 km of today's epicenter was an M 3.7 on October 20, 2018 and prior to that an M 3.1 on February 2, 2015. Forecast 130357 had expected today's event within about 35 km of this epicenter was likely around January 13.

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.

MODERATELY STRONG QUAKE IN SULAWESI, INDONESIA
EARTHQUAKE SUMMARY FOR JANUARY 13, 2021
The strongest earthquake in the world today was an M 5.7 in Sulawesi, Indonesia.
It was not reported felt in this area but was probably felt lightly in the epicentral area. This event occurred within about an hour of local solar noon and was probably enhanced by tidal stresses associated with the new moon as noted in previous issues of this summary:
"The new moon will arrive at 05:00 UT on January 13. Longitudes which are at sub-lunar conditions (local solar midnight) at this time are near 75 West and those at sub-solar conditions (local solar noon) are near 105 East. These include in the west, the west coast of South America and eastern North America and in the east western and central Indonesia, the Philippines and Taiwan among others. These areas are most likely to see tidally enhanced seismicity in the next week through January 17, 2021. Tidal enhancement is most likely near local solar noon and midnight. A strong global earthquake is likely in this period." (January 8-12, 2021)
It is also located near the geomagnetic equator and may have been promoted by the geomagnetic storm two days ago. Forecast 130260 had expected today's event within about 200 km of this epicenter was likely around January 16. This area often sees a series of moderate to large earthquakes and more such activity may be seen in the next several days. This epicenter is at the seventh node (51-52 degrees) from the M 6.7 in Mongolia of January 11 and may have been promoted by energy from that source.

The strongest earthquake in the U.S. or Canada today was an M 4.9 in the eastern Andreanof Islands, Aleutians, Alaska. It was not reported felt in this remote area. This is the strongest earthquake within about 150 km in the eastern Andreanof Islands since an M 5.3 on October 1, 2020 and prior to that an M 5.0 on February 13, 2020. Forecast 130432 had expected today's activity within about 100 km was likely around January 13.

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.

EARTHQUAKE SUMMARY FOR JANUARY 12, 2021
The strongest earthquake in the world today was an M 5.9 in New Guinea. NEIC reported it was felt with intensity VIII in Nabire, Papua New Guinea. This is the strongest earthquake within about 200 km of this epicenter since an M 6.1 about 200 km northeast of this and an M 6.3 event five days earlier on June 24 and June 19, 2019. An M 7.0 hit the area on July 27, 2015 and April 6, 2013.
This epicenter is at 103 degrees from southern California and appears to have promoted activity in that area in the past, usually with the strongest triggered events about a month later the the large quake in Papua. Forecast 130263 had expected today's event was likely in mid-January, 2021. This epicenter is near the sixth node (60 degrees) from the earthquake in Mongolia of January 11, 2020 and may have been promoted by energy from that source.

A series of moderate earthquakes occurred today in southern Greece. NEIC reported these events were felt with intensity V in Rododafni, Ahaia and IV in Lidorikion, Aiyion, Aktaio, Patrai, Demenika,and Agrinon and II-III in Rion, Stirion and Karpenision, Greece. Several aftershocks of M 4.7 were also felt in the area. These events appear to have been promoted by tidal stresses associated with the new moon which arrived within minutes of the M 5.1 in Greece. That event occurred within about 15 minutes of local solar midnight an hour when tidal stresses are maximized. This was noted in this and previous summaries as:
"The new moon will arrive at 05:00 UT on January 13. Longitudes which are at sub-lunar conditions (local solar midnight) at this time are near 75 West and those at sub-solar conditions (local solar noon) are near 105 East. These include in the west, the west coast of South America and eastern North America and in the east western and central Indonesia, the Philippines and Taiwan among others. These areas are most likely to see tidally enhanced seismicity in the next week through January 17, 2021. Tidal enhancement is most likely near local solar noon and midnight. A strong global earthquake is likely in this period." (January 8-12, 2021)
Local solar midnight occurs at 22:30 UT. The last earthquake within about 150 km of today's epicenter with M>=5.1 occurred as an M 5.3 on February 15, 2016. Forecast 130345 had expected today's activity was likely within about 50 km to occur around January 14, 2021. Today's activity is located near the third node (120 degrees) from the Dodecanese Islands M 7.0 of October 30, 2020 and at the sixth node (60 degrees) from the earthquake in Mongolia of January 11, 2020 and may have have been promoted by energy from those source.

The strongest earthquake in the U.S. or Canada today was an M 4.3-4.5 off the coast of Northern California. NEIC reported it was felt along the coast with intensity II-III in Northern California at Ferndale, Eureka, Trinidad, Quincy. The last activity within about 100 km of today's event with M>=4.3 was an M 4.8 on March 22, 2020, an aftershock of an M 5.8 on March 9, 2020. Forecast 130409 had expected today's event within about 25 km was likely around January 16, 2021.
Exactly 20 years ago an M 5.6 hit this same area off the coast of Northern California. It was widely felt along the coast. For more details see the "HISTORY" section of this summary.

The earthquake of M 6.7 in Russia/Mongolia and the M 6.0 in Northern Japan late on January 11 and early on January 12, 2021 were closely associated with a strong GRB which was first recorded early on January 12 about an hour before the quake in Hokkaido, Japan. Effects from this and the associated geomagnetic storm may have helped promote these earthquakes at this time. The specs on the GRB are not yet available but will be published in this report when available. Current data on this GRB is found in the EXTERNAL FIELDS section of this report as:
"The last major Gamma Ray Burst (GRB) according to the online NASA Swift GRB Catalog was observed on January 12, 2021 at 01:37 UT with BAT Fluence n/a erg/sqcm. (MAGNITUDE: n/a), Associated earthquake: Russia/Mongolia M 6.7 1-11 21:32 UT, Northern Japan M 6.0 1-12 02:39 UT)" (January 12-13, 2021)
Aftershocks continued today in the Russia-Mongolia area today with the strongest with magnitudes in the mid-fours. Forecast 130447 had expected this activity within about 150 km of this epicenter was likely around January 15.
NEIC reported the earthquake of M 4.4 and M 4.7 in Mongolia were felt with intensity II-III in the area(s) of Mongolian in Ulaanbaatr and in Irkutsk, Russia (IV).

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 EARTHQUAKES SHAKE MONGOLIA/SIBERIA AND HOKKAIDO, JAPAN
EARTHQUAKE SUMMARY FOR JANUARY 11, 2021
Strong earthquakes hit the regions of Mongolia and Siberia (M 6.7) and northern Hokkaido, Japan (M 6.0) today. The earthquake in Hokkaido was reported by NEIC with intensity III in Hokodate, Hokkaido and Misawa, Aomori, Japan.
The last earthquake of M>=5.9 within about 200 km of today's event in the eastern Sea of Japan was an M 7.7 on July 12, 1993. Forecast 130059 had expected today's event about 200 km to the east of today's epicenter was likely around January 9, 2021. This earthquake may have been promoted by tidal stresses associated with the new moon of January 13. It occurred within about 15 minutes of local solar noon, a time when tidal stresses are maximized as noted in this and previous issues of this summary:
"The new moon will arrive at 05:00 UT on January 13. Longitudes which are at sub-lunar conditions (local solar midnight) at this time are near 75 West and those at sub-solar conditions (local solar noon) are near 105 East. These include in the west, the west coast of South America and eastern North America and in the east western and central Indonesia, the Philippines and Taiwan among others. These areas are most likely to see tidally enhanced seismicity in the next week through January 17, 2021. Tidal enhancement is most likely near local solar noon and midnight. A strong global earthquake is likely in this period." (January 8-11, 2021)

The M 6.7 in Mongolia was widely felt in that area and in Siberia, Russia. The mainshock of M 6.7 was reported with minor damage in Moron, Hovsgol, Mongolia and IV in Shelekhov, Irkutsk, Erzin, Gusinoozyorsk, Burjatya, Russia and in Mongolia at Suhbaatar, Erdenet, and III in Usolye-Sibirskoye, Cheremkho, Angarsk, Irkutsk, Russia. Aftershocks of M 4.8 and M 5.0 were felt in Irkutsk, Russia (IV) and in Zuunharaa, Selenge, Mongolia (V). The mainshock occurred as the strongest geomagnetic storm in two months reached maximum at 21:00 UT as noted in this and previous issues of this summary as:
"The geomagnetic field saw active conditions today. The AP level was 14. High latitude geomagnetic field also saw minor storm conditions with AP 20. This is the strongest disturbance in the geomagnetic field since in more than a month - since AP index reached 27 on November 27, 2020. Geomagnetic storms such as this can bring increases seismicity at high latitudes and near the geomagnetic equator over the next several days." (January 11, 2020)
and
"The maximum disturbance in the geomagnetic field today occurred with KP 4 at 21:00, January 11, 2021." (January 11, 2021)
Today's event of M 6.7 is the strongest in the world in two weeks - since an M 6.7 in Los Lagos, Chile on December 27, 2020. The only earthquake within about 300 km of this epicenter of equal or larger magnitude in this region near the Russia-Mongolia border was an M 6.7 about 300 km to the west on February 26, 2012 - the only such event in this region in the past 30 years. This epicenter is at the seventh node (52 degrees) from both the Dodecanese Islands of October 30, 2020 and from the M 7.6 in the Alaska Peninsula of October 19, 2020. It is also located in the antipodal area of the M 6.7 in Los Lagos, Chile of December 27, 2020. It was probably promoted by energy from these sources. One of the strongest earthquakes in this area in recent times occurred as an M 7.5 on January 12, 1862 exactly 159 years ago. This is detailed in the "HISTORY" section of this report.

An M 5.4 was also felt in the Azores Islands of Portugal today. NEIC reported it was felt with intensity VI in Horta, Azores. This event may have been promoted by strong tidal stresses associated with the upcoming new moon of January 13. It occurred near local solar noon, an hour when such stresses are maximized. The M 5.4 is the strongest earthquake in the Azores within about 300 km of this epicenter since an M 5.5 on August 30, 2017, the strongest in the region since an M 6.2 on July 9, 1998 and the second largest in the past 30 years. Forecast 130075 and 130348 had expected today's activity within about 150 km was likely between January 9-12 with magnitude up to M 6.1.

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.

QUAKES AROUND NEW ZEALAND MAY INDICATE UPCOMING GLOBAL SEISMIC ENHANCEMENT
EARTHQUAKE SUMMARY FOR JANUARY 10, 2021
Earthquakes of M 5.5 each hit two oceanic ridge areas today - in the Southern East Pacific Rise and in the Balleny Islands south of New Zealand. These were not reported felt in these remote areas. The earthquake in the southern East Pacific Rise is the strongest within about 250 km of that epicenter since an M 5.7 on May 14, 2020 and prior to that an M 5.8 on September 27, 2019. Forecast 130183 had expected enhanced activity in this area was likely in early January, 2021. This earthquake is at 143 degrees of the Dodecanese quake of October 30, 2020 and may have been promoted by energy from that source.

An earthquake of M 4.5 occurred near the antipode of the M 5.5 in the East Pacific Rise about 30 minutes prior to that event and may have been related to it through external forces. Forecast 130336 had expected today's event wasl likely within about 100 km of this epicenter around January 12.

The M 5.5 south of New Zealand in the Balleny Islands was also located at an unusual epicenter. The last earthquakes within about 300 km of this epicenter in the Balleny Islands with M>=5.5 occurred in 2016 on January 31 (M 6.0) and June 15 (M 5.6). Today's event followed a series of unusual moderate earthquakes west of New Zealand. Events in this region often precede strong enhancement in global seismicity, especially in the area of the coast of South America as detailed in this summary several days prior to the last strong earthquake in the world - the M 6.7 in Los Lagos, Chile as:
"An unusual earthquake occurred northwest of New Zealand today with M 4.8. This is the strongest earthquake within about 300 km of this epicenter in at least 30 years. Previous earthquakes in this region have often occurred within hours or days of strong earthquakes in southern Chile as discussed in this summary on February 24-25, 2010, ten years ago, several days before an M 8.8 in Central Chile" (December 26-27, 2020)
Some of today's activity may be related to strong tidal stresses related to the upcoming new moon as noted in previous issues of this summary:
"The new moon will arrive at 05:00 UT on January 13. Longitudes which are at sub-lunar conditions (local solar midnight) at this time are near 75 West and those at sub-solar conditions (local solar noon) are near 105 East. These include in the west, the west coast of South America and eastern North America and in the east western and central Indonesia, the Philippines and Taiwan among others. These areas are most likely to see tidally enhanced seismicity in the next week through January 17, 2021. Tidal enhancement is most likely near local solar noon and midnight. A strong global earthquake is likely in this period." (January 8-10, 2021)

Much of today's unusual activity occurred at the very deep focus of 750 depth within a limited time. This included strong deep focus earthquakes of M 5.6 in the Flores Sea, the largest in the world today, as well as both events west of New Zealand and a smaller quake in Mendoza, Argentina. An external stressor may have been enabling of this activity.

The strongest earthquake in the U.S. or Canada today was an M 3.9 in the Alaska Peninsula. This epicenter is southeast of the aftershock zone of the October 19, 2020. M 7.6 in a somewhat unusual region of the Alaska Peninsula. The last earthquake within about 150 km of this epicenter with larger magnitude was an M 4.1 on October 19, 2020, in concert with the M 7.6 mainshock on that date. An M 4.1 hit the area two days before this on October 17, 2020 and may have been precursory to the M 7.6. Forecast 130430 had expected activity southwest of this around January 13.

The current swarm in Southern California near the Baja border continued today and included an M 3.3. This event occurred near local solar midnight and may have been enhanced by tidal stresses which maximize at this hour. This swarm restarted on January 4, 2021 with an M 4.0. Forecast 130359 had expected this activity around January 15.
NEIC reported these earthquakes of M 3.2 and M 2.7 in Southern California were felt with intensity II-III in the area(s) of Southern California in Calipatria, Westmorland, La Quinta and San Diego.

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 EARTHQUAKES IN VANUATU AND NORTHERN CHILE
EARTHQUAKE SUMMARY FOR JANUARY 9, 2021
Strong earthquakes in Vanuatu (M 6.1) and northern Argentina (M 6.1) continued seismic enhancement in those areas today. The earthquake of M 6.0-6.1 in Vanuatu was reported by NEIC to have been felt with intensity III in Luganville, Sanma, Vanuatu. The last earthquake within about 200 km of this epicenter in central Vanuatu with M>6.0 occurred with M 6.2 on September 6, 2020 with M 6.2 and prior to that as an M 6.4 on August 5, 2020. Forecasts 130161 and 130491 had expected today's activity within about 15 km was likely around January 8-12. This activity is near 103 degrees from the M 6.7 in Los Lagos of December 29, 2020 and was probably promoted by energy from that source.

The M 6.1 in northern Argentina was reported by NEIC to have been felt with intensity VI in Salta, Argentina; IV in Antofagasta, Chile and II in Iquique, Tarapaca, Chile. It was preceded by an M 4.5 foreshock that was felt with intensity III in Antofagasta. GUC reported this earthquake was felt with intensity IV in Antofagasta at Antofagasta, Calams, Mejillones and III in Taltal, Tocopilla; in Tarapaca with III in Iquique and II in El Loa, La Tirana, Pica, Pozo Almonte; and in Atacama with IV in Chararal, Diego de Almagro, El Salvador and III in Copiapo and Tierra Amarillo, Chile. This is the strongest earthquake within about 250 km of this epicenter since an M 6.3 on November 20, 2020 and prior to that an M 6.3 on April 15, 2017. Forecasts 130163 and 130165 had expected today's event was likely in early January. The quake occurred within about 30 minutes of local solar midnight and may have been enhanced by strong tidal stresses which are maximized at this hour. Maximum stress with the next full moon on January 13 is near this longitude as noted in the tidal forecast for that alignment in this summary:
"The new moon will arrive at 05:00 UT on January 13. Longitudes which are at sub-lunar conditions (local solar midnight) at this time are near 75 West and those at sub-solar conditions (local solar noon) are near 105 East. These include in the west, the west coast of South America and eastern North America and in the east western and central Indonesia, the Philippines and Taiwan among others. These areas are most likely to see tidally enhanced seismicity in the next week through January 17, 2021. Tidal enhancement is most likely near local solar noon and midnight. A strong global earthquake is likely in this period." (January 9-10, 2021)

An unusual earthquake of M 4.8 occurred today in the State of Chuuk, Micronesia. It was not reported felt in this remote area. The last earthquake of M>=4.8 within about 300 km of this epicenter occurred 10 years ago on November 26, 2011 after an M 5.7 on November 9, 2011. The only quake within 200 km of today's event at this magnitude was an M 4.8 about 150 km northwest on October 1, 1994. Forecast 130294 had expected enhanced regional seismicity around January 12, 2021.

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.

MODERATE QUAKES CONTINUE IN KERMADEC AND SOUTH SANDWICH ISLANDS
EARTHQUAKE SUMMARY FOR JANUARY 8, 2021
The strongest earthquake in the world today was an M 5.5 in central Vanuatu.
This follows an M 6.1 in southern Vanuatu yesterday. The last earthquake within about 100 km of today's epicenter was an M 6.4 on August 5, 2020. Several quakes of M6.0-6.2 hit about 100 km south of today's event in early September, 2020. Forecast 130161 had expected today's mainshock was likely within about 10 km of the epicenter around January 8, 2021. This follows a series in the southwest Pacific detailed in previous issues which occurred in Indonesia, Vanuatu and the Kermadec Islands associated with a moderate geomagnetic storm. Today's M 5.5 occurred within about 45 minutes of local solar noon and may have been enhanced by tidal stresses which maximize near this hour.

A moderate earthquake of M 5.2 also occurred today in the South Sandwich Islands. It was not reported felt in this remote area. The last earthquake of equal of greater magnitude in the South Sandwich Islands was an M 5.6 on January 4, 2021 and prior to that an M 5.2 on November 4, 2020. Forecast 130218 had expected today's earthquake was likely within about 100 km of this epicenter around January 5, 2021.

An earthquake of M 5.2 also occurred as an aftershock of yesterday's M 6.3 in the northern Kermadec Islands. Today's event occurred within about 15 minutes of local solar midnight and was probably promoted by tidal stresses which maximize near this hour. Forecast 130187 had expected today's activity was likely around January 6, 2021.

The strongest earthquake in the U.S. or Alaska today was an M 4.5 in the Fox Islands, Aleutians, Alaska. It was not reported felt in this remote area. The last earthquake in the Fox Islands of M>=4.5 was an M 4.5 on December 14, 2020. The last of larger magnitude was an M 6.4 about 200 km east of today's epicenter. Forecast 130104 had expected today's event in this region was likely around January 9, 2021.

Moderate earthquakes occurred today in the Virgin Islands with M 3.9 and 4.1.
The last earthquake located in the Virgin Islands with M>4.0 occurred on November 27, 2020 with M 4.2. Forecast 129937 had expected today's activity was likely within about 50 km of these epicenter around January 7. This activity is at the sixth node (60 degrees) from the M 6.7 in Los Lagos, Chile of December 27, 2020 and may have been promoted by energy from that source.

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.

MODERATE QUAKES CONTINUE IN KERMADEC AND SOUTH SANDWICH ISLANDS
EARTHQUAKE SUMMARY FOR JANUARY 8, 2021
The strongest earthquake in the world today was an M 5.5 in central Vanuatu.
This follows an M 6.1 in southern Vanuatu yesterday. The last earthquake within about 100 km of today's epicenter was an M 6.4 on August 5, 2020. Several quakes of M6.0-6.2 hit about 100 km south of today's event in early September, 2020. Forecast 130161 had expected today's mainshock was likely within about 10 km of the epicenter around January 8, 2021. This follows a series in the southwest Pacific detailed in previous issues which occurred in Indonesia, Vanuatu and the Kermadec Islands associated with a moderate geomagnetic storm. Today's M 5.5 occurred within about 45 minutes of local solar noon and may have been enhanced by tidal stresses which maximize near this hour.

A moderate earthquake of M 5.2 also occurred today in the South Sandwich Islands. It was not reported felt in this remote area. The last earthquake of equal of greater magnitude in the South Sandwich Islands was an M 5.6 on January 4, 2021 and prior to that an M 5.2 on November 4, 2020. Forecast 130218 had expected today's earthquake was likely within about 100 km of this epicenter around January 5, 2021.

An earthquake of M 5.2 also occurred as an aftershock of yesterday's M 6.3 in the northern Kermadec Islands. Today's event occurred within about 15 minutes of local solar midnight and was probably promoted by tidal stresses which maximize near this hour. Forecast 130187 had expected today's activity was likely around January 6, 2021.

The last earthquake located in the Virgin Islands with M>4.0 occurred on November 27, 2020 with M 4.2. Forecast 129937 had expected today's activity was likely within about 50 km of these epicenter around January 7. This activity is at the sixth node (60 degrees) from the M 6.7 in Los Lagos, Chile of December 27, 2020 and may have been promoted by energy from that source.

STRONG SEISMIC ENHANCEMENT CONTINUES IN SOUTHWESTERN PACIFIC AREA
EARTHQUAKE SUMMARY FOR JANUARY 7, 2021
Seismicity in the Southwestern Pacific near the geomagnetic equator continued
today with events of M 6.1 in Vanuatu and M 6.3 in the northern Kermadec Islands of New Zealand. The earthquake in the northern Kermadec Islands is part of an activation of the region which began on January 6, 2021 with an M 6.2. This was expected to continue as noted in the previous issue of this summary:
"Two earthquakes of M 4.9 each were recorded in the northern Kermadec Islands, of New Zealand today. They were not reported felt in this remote area. These appear to be aftershocks of the M 6.2 that hit the area yesterday. Strong earthquakes in the northern Kermadec Islands tend to occur in clusters and more of this activity is expected in the next several days." (January 6-7, 2021)
and
"The largest earthquake in the world today was an M 6.2 in the northern Kermadec Islands, New Zealand. It was not reported felt in this remote area. This is the strongest earthquake in the northern Kermadec Islands within about 200 km of this epicenter since an M 6.2 on June 21, 2019, an event which followed an M 7.2 about 300 km southwest of today's epicenter which occurred on June 15, 2019. Forecasts 130187 and 130167 had expected today's activity between January 6 and 9, 2021 was likely within about 10 km of today's epicenter." (January 5-6, 2021)
Forecast 130187 had expected today's event of M 6.3 was likely within about 100 km of this epicenter around January 6.

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.

GLOBAL SEISMICITY TURNS ACTIVE
EARTHQUAKE SUMMARY FOR JANUARY 6, 2021
It was an active in global seismicity. The largest earthquakes in the world occurred in New Guinea and Indonesia with the strongest of these an M 6.1 in the Minahassa, Sulawesi, Indonesia. Moderately strong earthquakes also were registered in Papua New Guinea west of the Solomon Islands (M 5.8) and Southern Sumatra, Indonesia (M 5.5). This activity may have been enhanced by effects from the current geomagnetic storm as most of it is located near the geomagnetic equator. For further details on this storm see the External Effects section of this and previous report.
The M 6.1 in Sulawesi, Indonesia was reported with intensity II at Gorontalo and in Luwuk, Sulawesi, Indonesia by NEIC. BMG reported this earthquake with M 6.5 was felt throughout the area of Sulawesi with intensity III-V. An M 6.1 hit within about 100 km of this epicenter on January 19, 2020 but the last of larger magnitude within about 200 km was an M 7.4 on November 16, 2008 about 200 km northwest of today's epicenter. Forecasts 129882 and 129919 had expected today's activity within about 100 km was likely in early January.

Two earthquakes of M 4.9 each were recorded in the northern Kermadec Islands, of New Zealand today. They were not reported felt in this remote area. These appear to be aftershocks of the M 6.2 that hit the area yesterday. Strong earthquakes in the northern Kermadec Islands tend to occur in clusters and more of this activity is expected in the next several days. Forecast 130167 had expected today's activity within about 15 km of these epicenter was likely around January 6.

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.
