MODERATE QUAKE SHAKES TAIWAN ON OTHERWISE QUIET DAY

 

EARTHQUAKE SUMMARY FOR FEBRUARY 20, 2024

 

Despite continuing quiet conditions in seismicity throughout the rest of the

world today, a set of moderate earthquakes with magnitude up to M 5.5 shook

the area of the southwestern Ryukyu Islands of Japan and Taiwan. NEIC reported this earthquake of M 5.0 in Taiwan was felt with intensity up to III in the area(s) of  Taiwan in Yonakuni, Japan. CWB reported these earthquakes of M 5.4=5.6 were felt with intensity I in Hualien, Yilan, Nantou, Taichung, Changhua, Taitung, Yunlin, Chiayi, Tainan, Hsinchu Counties, Taiwan. The last earthquake reported by NEIC in Taiwan of M>=5.6 was an M 5.6=5.7 on October 23, 2023. At the time this summary noted:

 

 

"A moderately strong earthquake of M 5.9 was felt widely in the region of the Ryukyu Islands and Taiwan today. NEIC reported maximum intensity IV in Taiwan in Taipei with lesser shaking in Ilan, and Okinawa, Japan. CWB reported the M 5.7 was felt with intensity III in Hsinchu, Hualien, Yilan, Changhua, Yunlin; II in Nantou, Taichung, Kaohsiung, Taitung, Chiayi, Miaoli, Taoyuan, Tainan and I in Penghu and Pingtung Counties, Taiwan. A larger event of M 5.8 hit Taiwan near this epicenter on October 11 but the last event in southwestern Ryukyu Islands of greater magnitude occurred as an M 5.7 on October 16, 2023 which was probably an aftershock of an M 6.4-6.8 on September 18 a month earlier but also with the new moon." (October 23, 2023)

 

Forecast 160801 had expected today's activity in Taiwan within about 100 km was likely around February 23, 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.

QUIET CONDITION PREVAIL IN GLOBAL SEISMICITY

 

EARTHQUAKE SUMMARY FOR FEBRUARY 19, 2024

 

The current seismic quiet in global seismicity continued today. No events of M>5.2 were reported. This is consistent with the current lack of triggering phenomena related to weather or solar/ionospheric effects. Several events of M 5.0-5.2 were reported felt today. This included events of M 5.1 in Galapagos, Ecuador; Central and Northern Peru and an M 5.2 in Pakistan. Data from EMSC for these events follow:

The strongest earthquake in the U.S. or Canada today was again an M 4.2 in the

Fox Islands, Aleutians. This was covered in the previous issue as:

 

"The strongest earthquake in the U.S. or Canada today was an M 4.2 in the central Fox Islands, Aleutians, Alaska. It was preceded by a foreshock of M 3.5 four minutes earlier. These events were not reported felt in this remote area. The last earthquake of equal or larger magnitude within about 200 km of this epicenter was an M 4.5 on December 27, 2023. At the time this summary noted:

 

"The strongest earthquake in the U.S. or Canada today continued the enhanced seismicity in the Fox and Unimak Islands of the Alaskan Aleutians. This follows regional increases in seismicity following the M 6.1 on December 21, 2023. Today's event is the strongest in the Fox Islands within about 200 km since a similar M 4.6 on November 12, 2023 but an M 5.6 hit the area about 200 km to the southwest of today's epicenter on November 28, 2023." (December 27, 2023, February 19, 2024)

 

Forecast 160639 had expected today's activity in the Fox Islands was likely within about 100 km of today's epicenter was likely around February 18, 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.

MODERATE QUAKE IN PACIFIC-ANTARCTIC RIDGE

 

EARTHQUAKE SUMMARY FOR FEBRUARY 18, 2024

 

The strongest earthquake in the world today was an M 5.1 in the Pacific-Antarctic Ridge. It was not reported felt in this remote area. The last earthquake of M>=5.1 within about 250 km of this epicenter occurred on December 5, 2023 with M 5.5 and M 5.4.

  

This earthquake occurred near local solar midnight and may have been promoted by strong tidal and/or geomagnetic stresses which maximize near this hour.

 

O: 18FEB2024 08:57:55  56.4S  142.1W MB=5.1  EMSC   PACIFIC-ANTARCTIC RIDGE      

 

An M 5.6 was also recorded in the area of Tonga and was followed by an M 4.6 near local solar noon today. It is likely this was promoted by strong tidal and/or geomagnetic stresses which maximize near this hour. Forecast 160681 had expected this activity in Tonga around February 16.

 

The M 5.6 was noted in the previous issue of this report as:

 

 

"The strongest earthquakes in the world today occurred as a set of events of M 5.6 and 5.3 in Tonga. These occurred at the longitude of maximum tidal stress with the new moon of February 9 and may have been promoted by tidal stresses associated with the previous new moon" (February 18, 2024)

 

 

Forecasts 160675, 160681 and 160598 had expected this activity in Tonga and

Fiji was likely in mid-February.

The strongest earthquake in the U.S. or Canada today was an M 4.2 in the central Fox Islands, Aleutians, Alaska. It was preceded by a foreshock of M 3.5 four minutes earlier. These events were not reported felt in this remote area. The last earthquake of equal or larger magnitude within about 200 km of this epicenter was an M 4.5 on December 27, 2023. At the time this summary noted:

 

"The strongest earthquake in the U.S. or Canada today continued the enhanced seismicity in the Fox and Unimak Islands of the Alaskan Aleutians. This follows regional increases in seismicity following the M 6.1 on December 21, 2023. Today's event is the strongest in the Fox Islands within about 200 km since a similar M 4.6 on November 12, 2023 but an M 5.6 hit the area about 200 km to the southwest of today's epicenter on November 28, 2023." (December 27, 2023)

 

Forecast 160639 had expected today's activity in the Fox Islands was likely within about 100 km of today's epicenter was likely around February 18, 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.

EARTHQUAKE SUMMARY FOR FEBRUARY 17, 2024

 

The strongest earthquakes in the world today occurred as a set of events of M 5.6 and 5.3 in Tonga. These occurred at the longitude of maximum tidal stress with the new moon of February 9 and may have been promoted by tidal stresses associated with the previous new moon as outlined earlier in this summary:

 

"The new moon arrived on February 9, 2024 at 22:59 UT.  Longitudes which were at local solar midnight at this time are located at about 15 East while those at local solar noon are near 165 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/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 full moon are considered  moderate high in the next week (February 4-14, 2024).

 

Forecasts 160675, 160681 and 160598 had expected this activity in Tonga and

Fiji was likely in mid-February.

An M 4.8-5.0 earthquake occurred today in the area of Guerrero, Mexico. NEIC reported it was felt with intensity IV in Guerrero in Tepetixtla. Press reported shaking as far as Acapulco and Mexico City with minor damage. EMSC reported it was strongly felt in Guerrero at Residencial Alinala, Paludismo, Del Valle Sur, Adolfo Ruiz Cortines. This event may have been promoted by energy from Tropical Storm Djoungou which is currently located at the antipode of this Mexican epicenter as reported in previous issues of this summary:

 

"TC Djoungou (TC 13S) continued today in the area of the south Indian Ocean with winds up to 80 kts.  It is expected to track to the southeast. It may enhance regional seismicity in the South Indian Ridge systems as it tracks through the area. The antipode is at 16N 112W, a non-seismic area but the storm will be moving to the west and the antipode to the east encountering western Mexico from Michoacan to Guerrero in several days. This could help promoted enhanced seismicity in that area at that time as Djoungou reaches speeds up to 130 kts." (February 16-17, 2024)

 

Although not expected to include a strong earthquake a continuing series of moderate earthquakes in Guerrero and possibly Michoacan, Mexico is expected as Djoungou tracks across the South Indian Ocean due to antipodal enhancement.

 

Forecast 160505 had expected the event of M 4.8 in Guerrero, Mexico today  was likely within about 100 km around February 17.

Aftershocks also continued to be felt in Southern Texas today following the M 4.7 in that region at midnight on February 17. Events of M 4.0 and M 2.6 were reported by NEIC to have been felt with intensity up to V in Falls City, Texas.

At the time this summary noted the coincidence of these earthquakes with the  strong X2.5 solar flare of February 16 as:

 

 

"The strongest earthquake in the U.S. or Canada today was an M 4.7 in southern Texas. This event was reported by NEIC to have been felt with intensity up to VI in Falls City, Texas. Aftershocks of M 3.7 and 3.3 followed and were felt in the same area. EMSC reported the mainshocks were felt as far as San Antonio where beds shook and people were awakened. It followed a series of foreshocks including an M 4.4 twelve minutes earlier which was felt with intensity up to V in Falls City, Texas. An M 3.9 foreshock  was also felt with intensity up to V in the Falls City area of Texas. Today's activity occurred within minutes of local solar midnight and may have been promoted by strong tidal stresses which maximize near this hour. An X2.3 solar flare occurred on February 16, 2024 when this epicenter was at local solar midnight. This flare may have helped trigger this unusually large earthquake. Data from SWPC for this flare follows;" (February 17, 2024)

Newly published data from SWPC confirms this speculation. These data show that a moderately strong C5.2 solar flare (#879) occurred simultaneously with the earthquakes in Texas which occurred  within several minutes of local solar midnight when Solar Flare Effects (SFE) maximize.  It is likely that SFE from Flare 870 triggered the events in Texas.

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 QUAKES SHAKE LOS ANGELES, CA; SOUTHERN TEXAS WITH X2.5 SOLAR FLARE

 

EARTHQUAKE SUMMARY FOR FEBRUARY 16, 2024

 

 

The strongest earthquake in the U.S. or Canada today was an M 4.7 in southern Texas. This event was reported by NEIC to have been felt with intensity up to VI in Falls City, Texas. Aftershocks of M 3.7 and 3.3 followed and were felt in the same area. EMSC reported the mainshocks were felt as far as San Antonio where beds shook and people were awakened. It followed a series of foreshocks including an M 4.4 twelve minutes earlier which was felt with intensity up to V in Falls City, Texas. An M 3.9 foreshock  was also felt with intensity up to V in the Falls City area of Texas. Today's activity occurred within minutes of local solar midnight and may have been promoted by strong tidal stresses which maximize near this hour. An X2.3 solar flare occurred on February 16, 2024 when this epicenter was at local solar midnight. This flare may have helped trigger this unusually large earthquake. Data from SWPC for this flare follows:

 

Flare #    START  MAX       END    CLASS     DATE    Flux (Jm-2)

 

 700       0642   0653      0721   X2.5      (February 16, 2024)   8.4E-02  

Central Peru M 4.4 06:54 UT

Sumatra M 3.9 06:55  UT

Los Angeles, California M 3.4 07:48 UT

 

Today's activity follows an M 3.9 in the same area of Texas which occurred on February 12, 2024 and was noted in this summary at the time as:

 

"An earthquake of M 3.8-3.9 also shook southern Texas today. NEIC reported it was felt with intensity up to IV in the Falls City, Texas area. The only earthquake within about 100 km of this epicenter of M>3.9 in the past 35 years were events of M 4.8 on October 20, 2011 and M 4.3 on April 9, 1993. An M 3.3 hit the same area on February 9, 2024. At the time this summary noted:

 

"A light earthquake of M 3.3 also occurred in Southern Texas today. NEIC reported this earthquake of M 3.3 in Southern Texas was felt with intensity up to IV in the area(s) of Southern Texas in Falls City. Light earthquakes in this region began  in late 2020. The largest earthquakes in the region in recent years were of M 3.9-4.0 on October 9, 2023 and September 14, 2023. Recent events in the area suggest triggering at this level in this area is likely at this time." (February 9, 2024)

 

 

Forecast 160528 had expected this activity within about 100 km in southern

Texas was likely around February 12, 2024.

 

Today's activity in southern Texas is at 103 degrees from the M 6.9 in the Northern Mariana Islands of November 24, 2023 and from  M 7.1 in the Loyalty Islands of December 7, 2023 and was probably promoted by energy from those sources.

An earthquake of M 3.5-3.8 also shook areas of eastern Los Angeles in the area of Riverside today. NEIC reported maximum intensity of IV in the area of Ontario, California. EMSC reported a loud earthquake rumbling noise and quick sharp tremor was felt in eastern Los Angeles in Ontario, Mira Loma, Corona, Chino, Norco, Rancho Cucamonga, Jurupa Valley, Chino Hills, Montclair, Fontana, Riverside, Upland, and as far as Ojai, Winnetka, Fallbrook, Venice and San Jacinto among others. This is part of a series of moderate tremors in southern California in the past week. All of these areas are located near 103 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and may have been promoted by energy from that source. This earthquake occurred within minutes of local solar midnight and may have been promoted by strong tidal stresses which maximize at this time. It also followed an X2.5 class flare which began at 06:42 UT and was officially over by about 07:21 UT (see flare listing below). An earthquake of M 4.4 in Central Peru was also closely related to this flare as was an M 3.9 in  Southern Sumatra at the antipodal longitude to Texas.  In the past year there have been three solar flares of X-class - an X6.0 on December 31, 2023; and X2.2 on February 9, 2024 and an X2.8 on December 14, 2023.

 

The last of these were closely associated with significant earthquakes in  the Los Angeles, California area. This summary emphasized this on February 9, 2024 as:

 

 

 

"A major solar flare of X3.3 occurred today (#9000 - SWPC). This is the strongest solar flare since an X5.0 on December 31, 2023 and probably had a great influence of the strong pulse of seismicity which followed and is described below. ... seismic enhancement included unusually strong earthquakes in western Los Angeles ...

 

It is likely that the X3.3 will trigger a CME which will cause a strong geomagnetic storm around February 12-15. This storm could trigger additional moderate seismicity in these areas as well and near the geomagnetic equator and under auroral ring currents in the coming days.

 

 

The moderate earthquake of M 4.6-4.7 was widely felt in the region of Los Angeles, California today. Press reports indicate it was felt by more than a million residents in the area of western Los Angeles and the San Fernando Valley to Malibu, California with maximum intensity up to V in Los Angeles. EMSC reported very strong shaking in Los Angeles, California at Westlake Village, Agoura Hills, Thousand Oaks, Oak Park, Casa Conejo, Newbury Park, Calabasas, Moorpark, Camarillo, Simi Valley, Woodland Hills, Canoga Park, Winnetka, Chatsworth, Northridge, Reseda, Tarzana, Chatsworth and as far as Dana Point, Loma Linda, Hesperia, and in Winterhaven and Yuma, Arizona. Many smaller aftershocks were felt in the same area.  Minor damage was reported in Los Angeles. This included some minor damage to structures and the temporary closure of regional theme parks such as Disneyland rides." (February 9, 2024)

 

 

and when a moderate quake hit the same area as today's event on January 1, 2024 it followed the X5.0 of December 31, 2023 and was noted in this report as:

 

"The strongest earthquake in the U.S. or Canada today was an M 4.1 in southern California south of Los Angeles. NEIC reported it was felt with intensity III in Rancho Palos Verdes, California. EMSC reported moderate to strong shaking without damage in California at San Pedro, Rancho Palos Verdes, Rolling Hills, Long Beach, Lomita, Seal Beach, West Carson, Signal Hill, Torrance, Rossmoor, Huntington Beach, Redondo Beach, Fountain Valley, Compton, Costa Mesa, Hawaiian Gardens, Westminster, Hermosa Beach among others. The only earthquakes with equal or larger magnitude than M 4.1  located within about 50 km of this epicenter in the past 35 years occurred on September 18, 2021 (M 4.3) and as an M 4.0 on May 15, 2013." (January 1, 2024)

 

This earthquake occurred within minutes of local solar midnight and was probably promoted by strong tidal stresses which maximize near this hour. Forecast 160573 had expected this event within about 25 km was likely around February 16, 2024.

This epicenter is at 103 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and was probably promoted by energy from that source.

An earthquake of M 3.5 was also felt in the area of Seattle, Washington today. NEIC reported this earthquake of M 3.5 in Washington State  was felt with intensity up to IV in the area(s) of   Washington State in Brinnon.  EMSC reported light shaking and slight rumble at Bremerton and Tacoma. The last earthquake of equal or larger magnitude in this area was an M 4.0 on December 24, 2023. At the time this summary noted:

 

 

"The strongest earthquake felt in the U.S. or Canada today was an M 4.0 in the Seattle area of Washington State. NEIC reported it was felt with light intensity up to III in Quilcene, Washington. EMSC reported light to moderate shaking in Navy Yard City, Clinton, Victoria, Bryant, and in Canada at North Saanich.

Local news reported the quake was felt as far south as Olympia and as far north as Vancouver, British Columbia and was felt lightly with intensity up to IV in Puget Sound, Seattle, Tacoma, Kent, Everett and Oak Harbor. While no damage was reported with today's event some people reported it was strong enough to wake them from their sleep. The M 4.0 occurred 22 minutes after an M 5.4 in Tonga and may have been triggered by seismic waves from that source. The time for an S-wave to travel from the Tonga epicenter to this epicenter in Washington State 81 degrees away is 22 minutes, so triggering is a distinct possibility in this instance as the earthquake was simultaneous with the arrival of the S-waves from Tonga. The last earthquake in the Puget Sound area of Washington with M>=4 occurred on October 8, 2023 as a M 4.3 and prior to that as an M 4.6 in 2019 near Monroe, Washington." (December 24, 2023)

 

Forecast 160618 had expected enhanced seismicity in this area was likely around February 15. This activity is near 101-103 degrees from recent major earthquakes in Mindanao, Philippines and was likely promoted by energy from those sources.

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 QUAKE IN CENTRAL PERU

 

EARTHQUAKE SUMMARY FOR FEBRUARY 15, 2024

 

The strongest earthquake in the world today was an M 5.2 near the coast of Central Peru. NEIC reported this earthquake of M 5.2 in Central Peru was felt with intensity up to V in the area(s) of  Central Peru in Chancay. EMSC reported moderate shaking in the area of Lima, Peru in Lima, Los Olivos, San Isidro, Miraflores, Santiago de Surco, Lurigancho, Barranco, Villa Maria del Triunfo, Chorrillos. This is the strongest earthquake in Central Peru within about 200 km of this epicenter since an M 5.4 on May 12, 2022 and an M 5.6 on January 7, 2022. At

the time this summary noted in this regard:

 

"An earthquake of M 5.6 was also widely felt in central Peru today. NEIC reported slight damage with intensity VII in Chosica, Loima, Peru with intensity V shaking in Ricardo Palma, Santa Maria, Lima and IV in San Luis, Chica, Mala, Lima Peru and possibly in Juno and Ica, Peru. This is the strongest earthquake within about 200 km of this epicenter since an M 5.8 about 100 km to the south of this on June 23, 2021 and prior to that an M 5.6

on November 15, 2014 near that same epicenter to the south." (January 7, 2022)

 

Forecast 160671 had expected enhanced seismicity in Central Peru was likely around February 12, 2024. This epicenter is at 144 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and may have been promoted by energy from that source.

The second strongest earthquake today was an M 5.0 in the South Indian Ocean west of Australia. It was not reported felt in this remote area. A series of events hit this region about 100 km to the north of this epicenter on October  14, 2022. Maximum magnitude in this series was an M 5.0-5.1.

 

Forecast 160441 had expected today's event within about 25 km was likely in early February, 2024.

The strongest earthquake in the U.S. or Canada today was an M 4.0 in the eastern Andreanof Islands. It was not reported felt in this remote area. This event occurred near local solar midnight and may have been promoted by tidal stresses which maximize near this hour. The last earthquake within about 150 km of this event in the Eastern Andreanof Islands was an M 5.0 on November 3, 2023. At the time this summary noted:

 

 

"The strongest earthquake in the U.S. today was an M 5.0 in the Aleutians near Atka, Alaska where it was lightly felt. An M 6.5-6.7 hit about 200 km west of this on October 16, 2023 but this is the strongest earthquake within 200 km of this epicenters in the Andreanof Islands since an M 5.1 on January 26, 2023. At the time this summary noted in this regard:

 

 

An M 5.2 earthquake was widely felt in Greece today. It was felt with intensity IV in Greece in Esfina, Calaxidion, Delfoi, Arakhova, Diakopton, Lekhaion, Isthmis Korinthia, Kineta (V), with III in Kirra, Fokis and Korinthos according to data from NEIC. This is the strongest earthquake in Greece within about 150 km of this epicenter since an M 5.5 on February 17, 2021 and an M 5.2 on January 12, 2021. The last earthquake in this area of M>5.5 was an 6.4 on June 8, 2008." (October 8, 2022, November 3, 2023)

 

Forecast 160635 had expected today's event within about 100 km was likely around February 14, 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.

STRONG EARTHQUAKE IN MICRONESIA

 

EARTHQUAKE SUMMARY FOR FEBRUARY 14, 2024

 

 

The strongest earthquake in the world today was an M 6.0 in Micronesia. NEIC reported it was felt with intensity up to IV in Micronesia near Colonia.  The last earthquakes of equal or greater magnitude within about 200 km of this epicenter in Yap, Micronesia occurred as event of M 6.5, 6.4 and 6.1 on December 8-9, 2017. At the time this summary noted:

 

"The largest earthquakes of the day occurred as an M 6.5 and 6.3 in the State of Yap, Micronesia. The first of these, an M 6.3 occurred within about half an hour of local solar noon and was probably promoted by tidal stresses which maximize at this time. It is also located on or near the geomagnetic equator and was probably promoted by the strong geomagnetic storm of the last several days. The last earthquake within about 200 km of this epicenter with M>=6.5 occurred on January 16, 2005 with M 6.6, the only other such event in the region in the past 25 years." (December 8, 2017)

 

Forecast 160490 had expected today's event within about 100 km was likely in  mid-February, 2024.

An M 5.8 also occurred in central Vanuatu today. It was not reported felt in this remote area. This epicenter is located at 103 degrees from the M 7.1 in  Xinjiang, China of January 22, 2024 and may have been promoted by energy  from that source. Forecast 160685 had expected today's event in Vanuatu was likely around February 15.

The strongest earthquake in the U.S. or Canada today was an M 4.7 in Central Alaska. NEIC reported it was felt with intensity up to M 4.7 in Petersville, Alaska. The only earthquake within about 150 km of this epicenter within about 150 km of today's epicenter with significantly larger magnitude was an M 5.0 on December 1, 2023. The only moderately large earthquake in the area in the past 25 years was an M 5.8 on November 29, 2000. At the time of the event of M 5.0 on December 1, 2023, this summary noted:

 

"... an M 5.0 in Central Alaska. NEIC reported this event was felt with intensity up to V in Petersville, Alaska. EMSC reported it was felt with moderate intensity in Central Alaska at Wasilla, Palmer, Knik-Fairview, Eagle River, Anchorage, This event occurred within minutes of the height of the arrival of the CME  around 06:00 UT (see above) and was probably triggered by that ionospheric disturbance.

 

The last earthquake within about 150 km of this epicenter with M>=5 in Central

Alaska occurred as an M 5.0 on October 4, 2019. Larger earthquakes hit about 200 km from today's epicenter on February 6, 2022 and May 31, 2021. At the time of the M 5.0 on October 4, 2019 this summary noted:

 

 

"Today's event was reported by NEIC to have been felt with maximum intensity V in the Matanuska-Sustina border of Alaska and II-III within about 200 km of the epicenter at Talkeetna, Willow, Wasilla, Chugiak, Elmendorf AFB, Anchorage.

This event of M 5.0 is the strongest within about 150 km of this epicenter in Central Alaska since an M 5.0 on July 10, 2018 - the last of larger magnitude was an M 5.2 on January 31, 2017. Today's event is about 150 km northwest of the M 7.1 quake that shook Alaska on November 30, 2018 and may be a regional aftershock of that event." (October 4, 2019, December 1, 2023)

 

Today's event occurred within minutes of local solar noon and may have been promoted by strong tidal stresses which maximize near this hour. Forecast 160394 had expected enhanced seismicity within about 25 km of this epicenter in early February, 2024.

The swarm in southern California continued today. The largest of the events today was an M 4.0. NEIC reported it was felt with intensity up to IV in Westmorland, California. EMSC reported moderate shaking in Southern California in Brawley, Imperial, Hemet, Twentynine Palms, Oceanside, Jurupa Valley, San Juan Capistrano, Lake Forest, Phelan. The M 4.2 occurred within minutes of local solar midnight and may have been promoted by high tidal stresses which maximize near this hour. The remainder of today's swarm occurred within about an hour of this time. Forecast 160572 had expected enhanced seismicity within about 25 km of this epicenter was likely around February 16, 2024. In the previous summary activity in this area was noted as:

 

"The largest earthquake in the U.S. or Canada today was an M 4.8 in Southern California. It was reported with intensity up to VI in the El Centro, California region. It was accompanied by a strong series of light aftershocks including some up to M 4.2. EMSC reported it was strong enough to waken all with pictures shifting and objects falling off shelves in El Centro. Minor damage was reported. Strong intensity was felt in El Centro, Imperial, Calexico, La Quinta, Lakeside, El Cajon, Indio, Chula Vista, Santee, Palm Springs and as far as San Diego and Los Angeles, California with light intensity and in Baja Mexico in Pueblo Nuevo, Nueva, Cuauhtemoc, Prohogar, and in Yuma, Arizona. The last earthquake in southern California within about 100 km of today's epicenter with M>=4.8 occurred as an M 4.8 on December 1, 2023 but the last of larger magnitude was an M 5.3 on June 5, 2021." (February 13, 2024)

 

Today's activity in southern California is at 104 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and was probably promoted by energy from that source. Today's activity in southern California is also at the fourth node (90 degrees) from the M 7.1 in the Loyalty Islands of December 7, 2023 and was probably 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.

STRONG EARTHQUAKE IN ATACAMA, CHILE

 

EARTHQUAKE SUMMARY FOR FEBRUARY 13, 2024

 

 

The strongest earthquake of the day was an M 6.0 in central Chile. NEIC reported it was felt with intensity up to VI in Vallenar, Chile. EMSC reported strong to moderate shaking in Atacama at La Serena, Coquimbo, Ovalle, Copiapo, Zapallar, Valparaiso, Lo Barnechea, Santiago, Quinta Normal, Nunoa, San Miguel, Chile. When a foreshock of M 5.4 occurred on January 11, 2024 this summary reported in this regard:

 

"A moderately strong earthquake also occurred today with M 5.4 in Central Chile today. NEIC reported it was felt with intensity up to V in Vallenar, Chile.

EMSC reported strong shaking in Chile at La Serena, Coquimbo, Diego de Almagro, Atacama, Independencia, Cartagena. It is the strongest event within about 200 km of this epicenter since an M 6.6 on October 31, 2023. This epicenter is near 144 degrees from the M 7.1 in Xinjiang, China of January 22, 2024. This is a distance at which significant seismic advancement is expected following major events. For example, at the time of the Chinese earthquake this summary noted:

 

 

"Areas most likely to see enhanced seismicity at distance from today's event in China lie near 103 and 144 degrees from that epicenter and include at 103 degrees Central California, Oklahoma, Hawaii and at 144 degrees Central Chile near Coquimbo and Peru and western Brazil" (January 22, 2024)

 

Forecast 160688 had expected this event was likely within about 25 km of this epicenter around February 13, 2024." (February 12, 2024)

 

Today's epicenter in Atacama is at 145 degrees from the M 7.1 in the Mariana Islands of November 24, 2023 and at 103 degrees from the M 7.2 in the Loyalty Islands of December 7, 2023 and may have been promoted by energy from that source.

A moderately large earthquake also occurred today in the South Sandwich Islands with M 5.7. It was followed by an aftershock of M 5.2 twelve minutes later which was probably triggered by PcS reflections from the mainshock. These are seismic pulses which reflect off the core back to the original epicenter. Larger aftershocks often occur at this time after the mainshock in most areas of the world (also see ScS and PcP times near 8 and 15 minutes after the mainshock). The last earthquake with M>=5.7 within about 200 km of today's epicenter occurred as an  M 5.8 on November 30, 2023. At the time this summary noted:

 

 

"The strongest earthquake in the world today was an M 5.8 in the South Sandwich Islands. This event was not reported felt in this remote area. A major earthquake of M 7.5 hit about 200 km southeast of today's epicenter on August 12, 2021 but the last earthquake within this range of today's event with equal of larger magnitude was recorded on August 18 and December 7, 2021 with M 5.8-5.9. Today's event was probably promoted by geomagnetic effects which maximize near the geomagnetic equator and at high latitudes." (December 1, 2023)

 

This is similar environmental conditions as current and is probably related to the timing of earthquakes in this area.

 

Forecast 160719 had expected today's event was likely within about 50 km around February 16, 2024.

 

Today's epicenter in the South Sandwich Islands, like the M 6.0 in Atacama, is near 144 degrees from the M 7.1 in the Mariana Islands of November 24, 2023 and at 103 degrees from the M 7.2 in the Loyalty Islands of December 7, 2023 and may have been promoted by energy from those sources. Other earthquakes today near 103 degrees from the Loyalty Islands today occurred in southern Texas; Guerrero, Mexico, and Oaxaca, Mexico and in Oklahoma.

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 SWARM IN SOUTHERN CALIFORNA

 

EARTHQUAKE SUMMARY FOR FEBRUARY 12, 2024

 

 

The largest earthquake in the U.S. or Canada today was an M 4.8 in Southern California. It was reported with intensity up to VI in the El Centro, California region. It was accompanied by a strong series of light aftershocks including some up to M 4.5.  EMSC reported it was strong enough to waken all with pictures shifting and objects falling off shelves in El Centro. Minor damage was reported. Strong intensity was felt in El Centro, Imperial, Calexico, La Quinta, Lakeside, El Cajon, Indio, Chula Vista, Santee, Palm Springs and as far as San Diego and Los Angeles, California with light intensity and in Baja Mexico in Pueblo Nuevo, Nueva, Cuauhtemoc, Prohogar, and in Yuma, Arizona. The last earthquake in southern California within about 100 km of today's epicenter with M>=4.8 occurred as an M 4.8 on December 1, 2023 but the last of larger magnitude was an M 5.3 on June 5, 2021. At the time of the M 4.8 on December 1, 2023 this summary noted in  this regard:

 

"The strongest earthquake in the U.S. or Canada today was an M 4.8 in Southern California. It occurred near Ocotillo where NEIC reported it was felt with intensity up to V. EMSC reported strong shaking in southern California at El Centro, Holtville, Borrego Springs, Bostonia, La Quinta, Poway, Temecula, Fallbrook, Hemet, San Jacinto, Moreno Valley, Woodcrest among others and in Mexico at Ejido El Faro, Lomas de Abasolo, El Robledo, Hacienda del Rio, Mexicali, Fraccionamiento Solidaridad, Fraccionamiento Venezia,  This event occurred within about 5 minutes of local solar midnight (07:43 UT whereas local solar midnight was at 07:21 UT). It is likely that it was promoted by strong geomagnetic and tidal stresses which maximize near this hour. It was followed by a series of light to moderate aftershocks and followed a number of regional foreshocks over the past several days. A foreshock of M 3.3 hit the area 8 minutes before the mainshock and was felt with intensity up to IV according to data from NEIC. This followed several hours after an M 2.7 which was felt lightly in Mecca, California. Aftershock sequences in this area can be quite extensive and continue strongly for several days. These often include events stronger than the first mainshock. This can be expected in the coming several days. This activity and an M 3.9 in Utah minutes earlier coincided with the expected severe geomagnetic storm associated with CME from the M9.8 solar flare of November 28 hitting the ionosphere with an arcjet about 05:12 UT to 06:33 UT. as noted in the previous issue of this summary:

 

 

"... the strongest solar flare since August 7, 2023 when an X1.5 was observed.

The largest solar flare in the past year was an X2.2 on February 17, 2023 (#630). Today's event in Oman occurred towards the end of the M9.8 class solar flare (#3400)." (November 29, 2023, December 1, 2023)

 

Today's activity began near local solar midnight - a time when tidal stresses maximize. It may have been promoted by tidal stresses with the new moon of February 9 as noted in previous issues of this summary:

 

"The new moon arrived on February 9, 2024 at 22:59 UT.  Longitudes which were at local solar midnight at this time are located at about 15 East while those at local solar noon are near 165 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/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 full moon are considered  moderate high in the next week (February 4-14, 2024)." (February 4-11, 2024)

 

Enhanced seismicity in this area began about the same time as the M 4.7 in  western Los Angeles of February 9. In previous summaries the initial stages of this swarm were noted in the previous issues of this summary as:

 

 

"Seismicity in the region of southern California today suddenly came to a halt at M>=2 levels. Only one such earthquake occurred in the entire state today. This may be a quiescence before a larger event as noted in the previous issue of this summary as:

 

 

"The current swarm in Baja and Southern California continued today in the  Calexico area.  NEIC reported these earthquakes of M 2.7, 2.8 in Southern California were felt with intensity up to III in the area(s) of Southern California at Westmorland. This activity may indicate the next area of Southern California where a moderate earthquake could occur in the coming days. Like the M 4.6 in Los Angeles yesterday it is located at 104 degrees from Xinjiang, China of M 7.1 which occurred on January 22, 2024 and at 103 from the M 6.3 in Papua, New Guinea in late December, 2023 and could be triggered by these recent earthquakes. This swarm has been gradually growing to higher magnitudes. Previous swarms which behaved in a similar way often lead to a moderate earthquake in the area within a couple of days and this is a possibility in today's case." (February 11-12, 2024)

 

Today's activity in southern California is at 104 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and was probably promoted by energy from that source. Today's activity in southern California is also at the fourth node (90 degrees) from the M 7.1 in the Loyalty Islands  of December 7, 2023 and was probably promoted by energy from that source.

 

A listing of events in this swarm that occurred today with M>=3 is below. A more complete listing of events of M>=2 can be viewed in the "CALIFORNIA" section of this summary. Forecast 160572 had expected today's activity within about  25 km was likely around February 12, 2024.

An earthquake of M 3.8-3.9 also shook southern Texas today. NEIC reported it was felt with intensity up to IV in the Falls City, Texas area. The only earthquake within about 100 km of this epicenter of M>3.9 in the past 35 years were events of M 4.8 on October 20, 2011 and M 4.3 on April 9, 1993. An M 3.3 hit the same area on February 9, 2024. At the time this summary noted:

 

"A light earthquake of M 3.3 also occurred in Southern Texas today. NEIC reported this earthquake of M 3.3 in Southern Texas was felt with intensity up to IV in the area(s) of Southern Texas in Falls City. Light earthquakes in this region began  in late 2020. The largest earthquakes in the region in recent years were of M 3.9-4.0 on October 9, 2023 and September 14, 2023. Recent events in the area suggest triggering at this level in this area is likely at this time." (February 9, 2024)

 

 

Forecast 160528 had expected this activity within about 100 km in southern

Texas was likely around February 12, 2024.

 

Today's activity in southern Texas is at 103 degrees from the M 7.1 in the Loyalty Islands of December 7, 2023 and was probably promoted by energy from that source.

The strongest earthquake in the world today was an M 6.1 in the Volcano Islands, Japan. NEIC reported it with light intensity in the epicentral region. The last earthquake of M>=6 in the Volcano Islands within about 150 km of today's epicenter occurred on 6.3 on August 16, 2016 and an M 7.5 on September 28, 2007 of M 7.5 and this is probably an aftershock of that event. A series of earthquakes hit about 200 south of today's epicenter in the Northern Mariana Islands starting with an M 6.9 on November 24, 2023.

 

Forecast 160534 had expected today's event within about 25 km was likely around February 12, 2024.

An earthquake of M 4.5-4.7 shook the area near Wellington, New Zealand in the Cook Strait area today. EMSC reported this earthquake of M 4.7 in North Island, New Zealand was felt with intensity up to III in the area(s) of  North Island, New Zealand in Paraparaumu with an earthquake noise. GEONET reported this event at M 4.7 was felt with moderate to strong intensity in the area southeast of Wellington, New Zealand and in southern North Island and northern South Island. 7319 reports of felt events were made of which 3978 reported weak and 2991 light intensity with 313 report of moderate shaking and 24 with strong and 3 severe and 9 with extreme intensity came from the area.  The last earthquakes of larger magnitude in the Cook Strait area of New Zealand occurred as an M 5.1 on August 10, 2023 and before that an M 5.7 on February 15, 2023. At that time this summary noted:

 

"Today's earthquake in the Cook Strait is the strongest in this region south of Wellington, New Zealand since an M 6,2 on January 20, 2014 about 150 km east of today's epicenter. Earthquakes about 150 km to the south of this occurred with M 6.4-6.5 in South Island on July 21 and August 16, 2013, the only such events in the region of Cook Strait in the past 35 years." (February 15. 2024)

 

Forecasts 160442 and 160712 had expected today's event in mid-February was likely within about 50 km of this epicenter.

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.

SEISMIC ENHANCEMENT AT 103 DEGREES FROM XINJIANG, CHINA CONTINUES

 

EARTHQUAKE SUMMARY FOR FEBRUARY 11, 2024

 

Moderately strong earthquakes continued today at 103 degrees from the M 7.1 of

January 22, 2024 in Xinjiang, China. These include an M 5.4 and 5.5 in the Central Mid-Atlantic and an M 5.0 in southern and northern Vanuatu. This suggest that the triggering potential of the Xinjiang quake is not yet finished.  A series of significant earthquakes at this distance from China have occurred in recent days in Los Angeles, California (M 4.7); Hawaii (M 5.7); Florida (M 4.0); Oklahoma (M 5.1); Melbourne, Australia (M 4.6); and Vanuatu (M 6.3) among others - a classic example of distant triggering of seismicity from a major earthquake.

 

The strongest earthquakes in the world today occurred as a pair of events of M 5.3 and M 5.5 in the Central Mid-Atlantic. They were not reported felt in this remote area. The last earthquake in the Mid-Atlantic within about 200 km of today's event with M>=5.5 occurred on February 25, 2019 but no events of significantly larger magnitude have been recorded in this area in the past 35 years.  Forecasts 160179 and 160451 had expected this event within about 100 km was likely between February 6 and 15, 2024. This epicenter is at 103 degrees from the M 7.1 in Xinjiang, China of January 22, 2024. It is likely it was promoted by energy from that source.

An earthquake of M 5.4 also occurred in southern Vanuatu today. It was reported with intensity up to IV. This epicenter is located at 103 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and may have been promoted by energy from that source. An M 6.3 hit about 200 km northwest of this epicenter on January 23, 2024. At the time this summary noted:

 

"The strongest earthquake in the world today was an M 6.3 in Central Vanuatu. NEIC reported it was felt with intensity up to VI in Vanuatu at Port-Vila.

EMSC reported a loud earthquake noise and strong shaking in Vanuatu at Port-Vila and Shefa. The last earthquake in Vanuatu within about 150 km of this epicenter with M 6.3 or greater was an M 6.3 on July 8, 2014. Today's epicenter is at 102 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and was probably promoted by energy from that source as identified in this summary" (January 23, 2024)

 

Forecast 160422 had expected today's earthquake was likely about 75 km

north of today's epicenter around February 10, 2024.

A moderately strong earthquake of M 5.4 shook areas of northern Mindanao, Philippines today. NEIC reported it was felt with intensity up to IV in Union, Philippines. PHIVOLCS reported it was felt with intensity III in General Luna and Dapa, Surigao del Norte and II in the Philippines in Bacuag, Burgos, Claver, Gigaquit, Mainit, San Benito, San Francisco, Tagan-An, and Tubod, Suriago del Noth, Carrascal, Surigao del Sur and with lesser intensity in Dinagat Islands. This epicenter is located at the seventh node (52 degrees) from the M 7.1 in Xinjiang, China of January 22, 2024 and was probably promoted by energy from that source. Several strong earthquakes have occurred in Mindanao since an M 7.6 on December 2, 2023 and stress redistribution  from those events also helped promoted today's event. It appears to be  an aftershock of the event in early December, 2023.

 

Forecasts 160453 and 160457 had expected today's event within about 100

km was likely around February 12, 2024.

A moderately strong earthquake also occurred today with M 5.4 in Central Chile today. NEIC reported it was felt with intensity up to V in Vallenar, Chile.

EMSC reported strong shaking in Chile at La Serena, Coquimbo, Diego de Almagro, Atacama, Independencia, Cartagena. It is the strongest event within about 200 km of this epicenter since an M 6.6 on October 31, 2023. This epicenter is near 144 degrees from the M 7.1 in Xinjiang, China of January 22, 2024. This is a distance at which significant seismic advancement is expected  following major events. For example, at the time of the Chinese earthquake this summary noted:

 

 

"Areas most likely to see enhanced seismicity at distance from today's event in China lie near 103 and 144 degrees from that epicenter and include at 103 degrees Central California, Oklahoma, Hawaii and at 144 degrees Central Chile near Coquimbo and Peru and western Brazil" (January 22, 2024)

 

Forecast 160688 had expected this event was likely within about 25 km of this

epicenter around February 13, 2024.

The strongest earthquake in the U.S. or Canada today was an M 4.8 in the Fox Islands, Aleutians, Alaska. It was not reported felt in this remote area. The area became active with an M 4.1 yesterday and was noted in the previous issue of this summary as:

 

 

"The strongest earthquake in the U.S. or Canada today was an M 4.1 in the Fox  Islands, Aleutians, Alaska. The last earthquake of M>=4.1 in the Fox Islands  occurred more than two months ago as an M 4.8 on December 4, 2023. This event, like today's was accompanied by moderate earthquakes in Los Angeles (M 3.5) and Hawaii (M 5.1) and by moderate aftershocks in Mindanao, Philippines on the same date.  At the time this summary noted:

 

 

"An earthquake of M 4.8 also shook regions of eastern Fox Islands, Aleutians today. Earthquakes within about 150 km of today's event with M>=4.8 in the western Fox Islands last occurred as an M 5.0 on November 3, 2023 and an M 5.6 on October 12, 2023. This earthquake occurred near local solar midnight and may have been promoted by energy associated with the geomagnetic storm of the past several days and/or by tidal stresses which maximize near this hour." (December 4, 2023)

 

Forecast 160368 had expected today's event within about 150 km was likely

around February 7, 2024." (February 11, 2024)

 

Forecast 160635 had expected today's earthquake was likely within about

50 km around February 14, 2024.

Seismicity in the region of southern California today suddenly came to a halt at M>=2 levels. Only one such earthquake occurred in the entire state today. This may be a quiescence before a larger event as noted in the previous issue of this summary as:

 

 

"The current swarm in Baja and Southern California continued today in the Calexico area.  NEIC reported these earthquakes of M 2.7, 2.8 in Southern California were felt with intensity up to III in the area(s) of Southern California at Westmorland. This activity may indicate the next area of Southern California where a moderate earthquake could occur in the coming days. Like the M 4.6 in Los Angeles yesterday it is located at 104 degrees from Xinjiang, China of M 7.1 which occurred on January 22, 2024 and at 103 from the M 6.3 in Papua, New Guinea in late December, 2023 and could be triggered by these recent earthquakes. This swarm has been gradually growing to higher magnitudes. Previous swarms which behaved in a similar way often lead to a moderate earthquake in the area within a couple of days and this is a possibility in today's case." (February 11, 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.

VERY QUIET SEISMICITY FOLLOWS ACTIVE DAY

 

EARTHQUAKE SUMMARY FOR FEBRUARY 10, 2024

 

Following a strong burst of seismicity with the full moon and X3.3 solar flare on February 9, 2024, seismicity dropped to extremely low levels in the world today. No earthquake of M>=5 were recorded in the past 24 hours.  The most active area of the world today was the central Gulf of California. This continues active seismicity in the area over the past week as noted in

the previous issue of this report:

 

 

"The strong series of earthquakes in the Gulf of California continued unabated today. This has been previously described in the past two issues of this summary. The strongest earthquakes in this series today were of M 4.7 and occurred at the maximum output of today's X3.3 solar flare and were probably triggered by that flare.  NEIC reported these earthquakes of M 4.4 and M 4.7 ... in the Gulf of California were felt with intensity up to III in the area(s) of the Gulf of California in Loreto, Mexico.

 

...

 

Forecasts 160245 and 160521 had expected this activity in the central Gulf of California was likely around February 7-13, 2024. This activity is at the fourth node (90 degrees) from the M 7.1 in the Loyalty Islands of December 7, 2023 and the M 7.6 in western Honshu, Japan of January 1, 2024 and at the seventh node (51 degrees) from the M 6.8 in Brazil of January 20, 2024 may have been promoted by energy from those sources." (February 8-10, 2024)

The strongest earthquake in the U.S. or Canada today was an M 4.1 in the Fox Islands, Aleutians, Alaska. The last earthquake of M>=4.1 in the Fox Islands  occurred more than two months ago as an M 4.8 on December 4, 2023. This event, like today's was accompanied by moderate earthquakes in Los Angeles (M 3.5) and Hawaii (M 5.1) and by moderate aftershocks in Mindanao, Philippines on the same date.  At the time this summary noted:

 

 

"An earthquake of M 4.8 also shook regions of eastern Fox Islands, Aleutians today.  Earthquakes within about 150 km of today's event with M>=4.8 in the western Fox Islands last occurred as an M 5.0 on November 3, 2023 and an M 5.6 on October 12, 2023. This earthquake occurred near local solar midnight and may have been promoted by energy associated with the geomagnetic storm of the past several days and/or by tidal stresses which maximize near this hour." (December 4, 2023)

 

Forecast 160368 had expected today's event within about 150 km was likely

around February 7, 2024.

An M 4.1 also occurred near the coast of Northern California today. NEIC reported this earthquake of M 4.1 off the coast of northern California  was felt with intensity up to III in the area(s) of northern California in Petrolia.  The last earthquake in this area within about 50 km with larger magnitude occurred on November 11, 2023 (M 4.8) and October 1, 2023 (M 4.1). These were aftershocks of an M 4.7 on September 30, 2023 and was noted in this summary at the time as:

 

"The strongest earthquakes in the U.S. or Canada today occurred off the coast of northern California. NEIC reported the largest of these - of M 4.7 was felt with maximum intensity V in California at Loleta and IV in Ferndale, Fortuna, Rio Dell, Hydesville, Eureka, Petrolia and Samoa. An aftershock of M 4.2 was felt with intensity IV in Ferndale, Loleta and III in Rio Dell, Fortuna, Petrolia, Hydesville and Scotia among others. An M 3.7 aftershock was also felt with intensity II-III in northern California in Hydesville, Eureka and Whitethorn.

 

NEIC reported this earthquake of M 4.1 off the coast of northern California  was felt with intensity up to III in the area(s) of northern California in Petrolia.  The last earthquake off the coast of Northern California with M>=4.7 was an M 5.6 on May 21, 2023. A strong  M 6.4 hit the area on December 20, 2022. At the time this summary noted:

 

 

"Today's M 6.4 is the strongest within about 200 km of this epicenter in Northern California since an M 6.8 on March 10, 2014 and an M 6.5 on January 10, 2010 and an M 7.1 on June 15, 2005, the only such earthquakes in this area in at least 25 years." (December 20, 2022, September 30, 2023)

 

 

Today's earthquake occurred near local solar midnight and may have been promoted by strong tidal stresses with the new moon of February 9 as previously defined in this summary:

 

"The new moon arrived on February 9, 2024 at 22:59 UT.  Longitudes which were at local solar midnight at this time are located at about 15 East while those at local solar noon are near 165 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/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 full moon are considered  moderate high in the next week (February 4-14, 2024)." (February 4-10, 2024)

 

Forecast 160345 had expected today's event within about 50 km was likely around February 8, 2024.

The current swarm in Baja and Southern California continued today in the Calexico area.  NEIC reported these earthquakes of M 2.7, 2.8 in Southern California were felt with intensity up to III in the area(s) of Southern California at Westmorland. This activity may indicate the next area of Southern California where a moderate earthquake could occur in the coming days. Like the M 4.6 in Los Angeles yesterday it is located at 104 degrees from Xinjiang, China of M 7.1 which occurred on January 22, 2024 and at 103 from the M 6.3 in Papua, New Guinea in late December, 2023 and could be triggered by these recent earthquakes. This swarm has been gradually growing to higher magnitudes. Previous swarms which behaved in a similar way often lead to a moderate earthquake in the area within a couple of days and this is a possibility in today's case.

 

Forecast 160295 had expected this area would be active around February 7 within about 50 km of these epicenters.

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.

X3.3 SOLAR FLARE; NEW MOON BRING SIGNIFICANT SEISMICITY

 

EARTHQUAKE SUMMARY FOR FEBRUARY  9, 2024

 

A major solar flare of X3.3 occurred today (#9000 - SWPC). This is the strongest solar flare since an X5.0 on December 31, 2023 and probably had a great influence of the strong pulse of seismicity which followed and is described below. The stresses from this flare as well as those associated with the completion of the new moon tidal alignment today contributed to a strong enhancement of global seismicity especially at 103 degrees from Xinjiang, China today. This seismic enhancement included unusually strong earthquakes in western Los Angeles, California (M 4.7); Hawaii (M 5.7); an M 6.1 in the Kermadec Islands and an M 5.8 in northern Mindanao, Philippines. It is likely that the X3.3 will trigger a CME which will cause a strong geomagnetic storm around February 12-15. This storm could trigger additional moderate seismicity in these areas as well and near the geomagnetic equator and under auroral ring currents in the coming days.

 

The X3.3 flare is the strongest recorded by SWPC since an X5.0 of December 31, 2023 which was followed by a similar series of major earthquakes including the M 7.6 in Western Honshu of January 1, 2024. This was noted in the issue of this summary at the time:

 

"A major solar flare of X5.0 (SWPC #40) began at 21:36 UT - late on December 31, 2024. This flare is the strongest since September, 2017 as described in a previous issue of this summary as:

 

"Today's solar flare of X2.8 is the strongest solar flare thus far in the current active cycle of the sun. The last solar flare of stronger class was an X8.3 on September 10, 2017 (#9040) and an X9.3 on September 6, 2017 (#7340)." (December 14, 2023)

 

Data from SWPC for the flare of December 31, 2023 and February 9, 2024 follow:

Gulf of California M 4.7 13:22 UT

 

"It is likely that this flare will be followed in the next day by an SFE induced earthquake and later by seismicity promoted by ionospheric reactions to  CME associated with this event. Areas most likely to see Solar Flare Effect (SFE) are generally in the north-western Pacific plate boundary including areas of Japan which saw an M 6.3 two days ago in the region of Hokkaido. A strong to major earthquake is possible shortly in this region. Later enhanced seismicity should be concentrated about 10 degrees north or south of the geomagnetic equator and at high latitudes under ionospheric ring currents." (January 1, 2024)

 

NEW MOON TIDAL EFFECTS

 

Tidal stresses were probably important in the timing of today's M 6.1 in the

Kermadec Islands, New Zealand; the M 5.7 in Hawaii and the M 4.7 in Los Angeles, California. These events occurred near local solar noon when tidal stresses maximize. This summary had noted possible seismic effects with this new moon in this and previous issues as:

 

"The new moon will arrive on February 9, 2024 at 22:59 UT.  Longitudes which are at local solar midnight at this time are located at about 15 East while those at local solar noon are near 165 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/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 full moon are considered  moderate high in the next week (February 4-14, 2024)."  (February 4-9, 2024)

 

LOS ANGELES, CALIFORNIA

 

The moderate earthquake of M 4.6-4.7 was widely felt in the region of Los Angeles, California today. Press reports indicate it was felt by more than a million residents in  the area of western Los Angeles and the San Fernando Valley to Malibu, California with maximum intensity up to V in Los Angeles. EMSC reported very strong shaking in Los Angeles, California at Westlake Village, Agoura Hills, Thousand Oaks, Oak Park, Casa Conejo, Newbury Park, Calabasas, Moorpark, Camarillo, Simi Valley, Woodland Hills, Canoga Park, Winnetka, Chatsworth, Northridge, Reseda, Tarzana, Chatsworth and as far as Dana Point, Loma Linda, Hesperia, and in Winterhaven and Yuma, Arizona. Many smaller aftershocks were felt in the same area.  Minor damage was reported in Los Angeles. This included some minor damage to structures and the temporary closure of regional theme parks such as Disneyland rides.

 

This was the strongest earthquake in the Los Angeles, CA area since an M  5.1 on August 20, 2023 and an M 5.3 on April 5, 2018 and is near the epicenter of the Northridge earthquake of M 6.7 of January 17, 1994 and the M 6.8 in San Fernando Valley of February 9, 1971. Active seismicity in this region at this time was first proposed in this summary following the M 6.3 earthquake in New Guinea of December 31, 2023 as:

 

 

"The strongest earthquake of the day was an M 6.3 in the region of West Irian, New Guinea. NEIC reported it was felt with intensity up to VI in the epicentral area near Abepura, Indonesia.

...

 

Strong earthquakes in the  region of Papua, Indonesia can precede enhanced seismicity in Southern California by about a month at a distance of 103 degrees on the earth's surface. A typical example was the M 8.1 in this area on January 10, 1971 followed by the M 6.7 San Fernando earthquake in Los Angeles of February 9, 1971. A similar example occurred in October, 1979 when the Superstition Hills quake in southern California followed a major quake in this area of New Guinea." (December 31, 2023)

 

Since that time this summary has expanded this watch following the M 7.1 in Xinjiang, China of January 22, 2024. Since that event significant earthquakes have been recorded near 103 degrees from that epicenter in Vanuatu, Florida, Oklahoma,  Melbourne, Australia, the Central Atlantic, and Hawaii among others. This was expected in the issue of January 22, 2024 as:

 

 

"Areas most likely to see enhanced seismicity at distance from today's event in China lie near 103 and 144 degrees from that epicenter and include at 103 degrees Central California, Oklahoma, Hawaii ..." (January 22, 2024)

 

and has been emphasized in many more recent summaries. Today's event follows a series of light regional earthquakes which have put residents on notice that a stronger earthquake may be imminent. For example on January 25, 2024 an M 4.2 shook eastern Los Angeles and was described in part in this summary as:

 

"A moderate earthquake of M 4.2 was widely felt with some minor damage and strong shaking in the region of Southern California near San Bernardino today. NEIC reported maximum shaking in San Bernardino with intensity up to V. EMSC reported moderate to strong shaking in Southern California was felt in San Bernardino, Colton, Loma Linda, Rialto, Riverside, Fontana, Highland, Redlands, Jurupa Valley, Moreno Valley, Rancho Cucamonga, Mentone, Mira Loma, Ontario, Yucaipa, Norco among others. This continues a series of moderate earthquakes that began with the arrival of the year 2024 and has included most recently an M 4.3 on August 29, 2018 and a similar event of 4.2 on January 5, 2024.

At the time this summary noted:

 

"The strongest earthquake in the U.S. or Canada today was an M 4.2-4.4 in the region of eastern Los Angeles, California. NEIC reported this earthquake of M 4.2 in Los Angeles, California was felt with intensity up to V in the area(s) of Los Angeles, California in Lytle Creek.  EMSC reported moderate to strong shaking in the region of Los Angeles was felt in Fontana, Phelan, Rancho Cucamonga, Pinon Hills, Muscoy, Rialto, Crestline, Upland, Bloomington, Hesperia, Rialto, San Bernardino, Colton, Mountain View Acres, Glen Avon, Lake Arrowhead, Ontario, Glen Avon, Montclair, Highland and as far as Hollywood, Torrance nearly 100 km from the epicenter. This event follows a similar M 4.2 in the Rancho Palos Verdes area of California. This was noted in this summary on January 1, 2024 as:

 

"The strongest earthquake in the U.S. or Canada today was an M 4.1 in southern California south of Los Angeles. NEIC reported it was felt with intensity III in Rancho Palos Verdes, California. EMSC reported moderate to strong shaking without damage in California at San Pedro, Rancho Palos Verdes, Rolling Hills, Long Beach, Lomita, Seal Beach, West Carson, Signal Hill, Torrance, Rossmoor, Huntington Beach, Redondo Beach, Fountain Valley, Compton, Costa Mesa, Hawaiian Gardens, Westminster, Hermosa Beach among others. The only earthquakes with equal or larger magnitude than M 4.1  located within about 50 km of this epicenter in the past 35 years occurred on September 18, 2021 (M 4.3) and as an M 4.0 on May 15, 2013." (January 25, 2024)

 

Today's epicenter in Los Angeles, California is located at 103 degrees from the Xinjiang, China epicenter of January 22, 2024 and was probably promoted by  energy from that source. It occurred near local solar noon at the time of the new moon as noted in previous summaries (see above).

 

 

Forecasts 160299, 160303 and 16574 had expected today's events within about 10 km was likely around February 8-12, 2024. These epicenters are located at 103 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and were probably promoted by energy from that source (but see also the relation to the M 6.3 in New Guinea of December 30, 2023 is also at 103 degrees from today's activity in Southern California) and at the sixth node (60 degrees) from the M 6.8 in Brazil of January 20, 2024. This is also located at 105 degrees from the M 7.6 of December 2, 2023. Other events at this distance from Mindanao today included a series of light to moderate earthquakes up to M 4.2 in northern Italy.

HAWAII

 

The strongest earthquake in the U.S.  today was an M 5.7 in the Mauna Loa region of Hawaii (initially given as M 6.3). NEIC reported it was felt as far as Honolulu and throughout the island of Hawaii with intensity up to VII. Foreshocks of M 2.9 and 3.0 were also reported felt in Pahala, Hawaii with intensity up to IV.  EMSC reported strong to violent shaking in Hawaii at Naalehu, Mountain View (with oud earthquake nose) Kealakekua, Fern Acres, Keaau, Pahoa, Hilo, Kailua Kona, Pepeekeo, Honokaa, Wailea, Wailuku, Maui, Lahaina, Honolulu, Kailua, Kaneohe, Jbphh, r.Minor damage which included items being thrown from shelves  and minor damage to structures was reported which included cracked walls. This is the strongest earthquake in Hawaii since an M 6.2 on October 10, 2021 and an M 6.9 on May 4, 2018 - the largest in Hawaii in the past 35 years. the only other event in Hawaii with M>=6.2 in this time period was an M 6.7 on October 15, 2006.  At the time of the October, 2021 event this summary noted:

 

“A strong earthquake of M 6.2 shook most of the state of Hawaii, U.S. today. It was reported with maximum intensity VI in Naalehu; V in Hawaii National Park, Captain Cook, Honaunau, Volcano, Mountain View, IV in Pahala, Holualoa, Pahoa, Kealakekua with lesser shaking as far to the west as Waimea. There have been only two earthquakes in Hawaii with M>=6.2 in the past 30 years – both north of today's epicenter in central and northern Hawaii Island - on May 4, 2018 with M 6.9 and as an M 6.7 on October 15, 2006. Today's earthquake occurred near the Loi'hi Seamount south of Hawaii and is not directly associated with the current major eruption of Kilauea volcano to the north. The shaking caused some doors to open and some items to be thrown from shelves in businesses. No major damage or casualties were reported and a tsunami does not appear to have been generated with this earthquake. The earthquake occurred within minutes of the maximum of a geomagnetic storm at local solar noon and was probably promoted by high tidal stresses associated with the new moon and the geomagnetic storm, which stresses maximize near this hour,  as noted in this and previous issues of this summary as:

 

"The New moon arrived at 11:05 UT on October 6. Longitudes which were at local solar noon at this time are near 15 East while those at local solar midnight are near 165 West longitude. In the west these include most areas of Europe and Africa and in the east the central Aleutians and the Alaska Peninsula, Hawaii and the Tonga-Fiji-Kermadec arc. These area are the most likely to see a strong tidally triggered earthquake in the next week. Other areas may also see tidal triggering. These are most likely to occur near local solar midnight and local solar noon. The possibility of a strong to major earthquake is considered moderate to strong before October 10." (October 4-10, 2021)

 

Readers should note that Hawaii is located near the longitude of maximum tidal stress with this new moon. ..." (October 10, 2021)

 

Today's activity follows a series of smaller earthquakes in  the region which began shortly after the earthquake in Xinjiang, China. This summary has followed this sequence in Hawaii mostly because it is located, like the event in Los Angeles today at 103 degrees from the Xinjiang, China  epicenter. A typical report on this follows:

 

"The strong series of minor earthquakes continued in Hawaii today albeit at a less intense level. Light earthquakes were felt with intensity I-III in Pahala, Hawaii according to NEIC. This summary noted this series of earthquake near Pahala, Hawaii in the previous issue as:

 

"The seismic swarm in Hawaii continued today with a number of events exceeding

M 3.0 including an M 3.4, 3.4, and 3.4.  NEIC reported these earthquakes of M 3.3, 3.5 ... in Hawaii were felt with intensity up to III in the area(s) of  Hawaii at Volcano. This follows seismicity in the region which reported in the previous issue of this summary in part as:

 

"A major increase in low-level seismicity has been occurring in the area south of Kilauea, Hawaii. USGS and Hawaii Volcano Observatory (HVO) reported there was deformation of the ground including swelling. This often occurs before an eruptive cycle and the alert level at Kilauea Volcano was elevated although no eruption is currently in progress. The strongest of today's events in Hawaii today was an M 3.0 but earthquakes of M 3.3 and 3.4 occurred yesterday.  This  summary does not anticipate a major eruption at this time. This activity is most likely due to energy from the M 7.1 in Xinjiang, China of January 22. The first signs of enhanced seismicity in Hawaii appears within a few days of the Xinjiang earthquake which is located at 103 degrees from Hawaii. This summary made this connection immediately and reported it on January 22, 2024 as:

 

"Areas most likely to see enhanced seismicity at distance from today's event in China lie near 103 and 144 degrees from that epicenter and include at 103 degrees Central California, Oklahoma, Hawaii" (January 22, 2024)

 

The other areas  - Oklahoma and/or Central California - noted in this previous report have not yet seen a significant earthquake, but this also is highly likely in the next week." (February 2-3, 2024)

 

Forecast 160498 had expected today's mainshock, which occurred near local solar noon, was likely within about 25 km around February 12, 2024. Today's event in Hawaii is located 102 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and was probably promoted by energy from that source. It is also at the sixth node (60 degrees) from the M 7.6 in Honshu, Japan of January 1, 2024 and may have been promoted by energy from that source.

KERMADEC ISLANDS, NEW ZEALAND

 

The strongest earthquake in the world today was an M 6.1 in the Kermadec Islands, New Zealand. It was not reported felt in this remote area. This event occurred near local solar midnight and may have been promoted by tidal stresses which maximize near this hour. The last earthquake in this region of the Kermadec Islands with M>=6.1 occurred on April 24, 2023 (M 7.1) and March 16, 2023 (M 7.0).

 

The M 6.1 in the Kermadec Islands, New Zealand is the strongest within about 200 km of that epicenter since an M 7.1 on April 24, 2023. At the time this summary noted:

 

"A major M 7.1-7.2 earthquake occurred at the height of this geomagnetic storm in the area of the Kermadec Islands, New Zealand. A tsunami of small height was possible with this earthquake but only locally. ... An M 6.9 in the Kermadec Islands of March 4, 2023 followed a major geomagnetic storm of February 27-28, 2023." (April 24, 2023)

 

Today's M 6.1 in the Kermadec Islands is probably an aftershock of the M 7.1 of April 24, 2023.  Forecast 160433 had expected today's event within about 25 km was likely around February 7, 2024.

MINDANAO, PHILIPPINES

 

An M 5.8-5.9 (PHIVOLCS) also occurred today in Mindanao, Philippines. NEIC reported it was felt with intensity up to VIII in the epicentral area near Maygatasan and Tungao, Philippines.  An aftershock of M 5.4 was felt in a similar area. PHIVOLCS repored this activity was felt with intensity up to V in Las Nieves, Agusan Del Norte; IV in Libona and San Fernando, Bukidnon; City of Iligan; City of Gingoog, Jasaan, Magsaysay and Medina, Misamis Oriental; City of Bayugan, Prosperidad and Talacogon, Agusan Del Sur and in III in Bohol, Bukidnon, Misamis Oriental, Davao de Oror, Davao del Dur, City of Davao and Surigao Del Sur among others. EMSC reported severe shaking with the mainshock of M 5.8-5.9 in Butuan City, Malaybalay, Cagayan de Oro, Mambajao, Davao City, Santa Cruz, Digos City, Barangaym Kapatagan, Dumaguete City. EMSC reported strong shaking in Butuan City, Mambajao, Cagayan de OroDavao City, for the M 5.4 aftershock.  A landslide in the area yesterday was being examined by rescue workers at the time of the earthquake. Workers were evacuated and have not returned to the site at this writing. This epicenter is about 100 km west of the M 7.6 in the area of December 2, 2023 and does not appear to be a classical aftershock of that event but may have been promoted by stress redistribution from that source. It appears to be the strongest aftershock to date of that event.

 

Forecast 160185 and 160453 had expected today's activity in Mindanao was likely within about 50-100 km of today's epicenters around February 8-12, 2024.

GULF OF CALIFORNIA

 

The strong series of earthquakes in the Gulf of California continued unabated today. This has been previously described in the past two issues of this summary. The strongest earthquakes in this series today were of M 4.7 and occurred at the maximum output of today's X3.3 solar flare and were probably triggered by that flare.  NEIC reported these earthquakes of M 4.4 and M 4.7 ... in the Gulf of California were felt with intensity up to III in the area(s) of the Gulf of California in Loreto, Mexico.

 

The data for these two events of M 4.7 is listed below but a more extensive listing can be found in the "AMERICA" section of this report.

 

Forecasts 160245 and 160521 had expected this activity in the central Gulf of California was likely around February 7-13, 2024. This activity is at the

fourth node (90 degrees) from the M 7.1 in the Loyalty Islands of December 7, 2023 and the M 7.6 in western Honshu, Japan of January 1, 2024 and at the seventh node (51 degrees) from the M 6.8 in Brazil of January 20, 2024 may have been promoted by energy from those sources." (February 8, 2024)

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.

EARTHQUAKES IN CENTRAL MID-ATLANTIC; SE AUSTRALIA AT 103 DEGREES FROM XINJIANG

 

EARTHQUAKE SUMMARY FOR FEBRUARY  8, 2024

 

The strongest earthquake in the world today was an M 5.1 in the area of the Central Mid-Atlantic Ocean. The last earthquake of M>=5.1 within about 200 km of this epicenter in the Central Mid-Atlantic occurred on July 3, 2007.  Today's epicenter is at 103 degrees from the M 7.1 in Xinjiang, China of January 22, 2024. This distance has been very active since that Chinese mainshock and has most recently included significant activity in Hawaii, Southern California, Oklahoma, Florida. Vanuatu as well as in SE Australia (see below) among others.

 

Forecast 160179 had expected today's event was likely in this region around

February 8. This epicenter is at 103 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and may have been promoted by energy from that source.

An earthquake of M 4.5 was widely felt today in the Melbourne area of Australia in the in the Gippsland region of Victoria. The quake centered near Leongatha and was felt as far north as Sunbury in Melbourne and as far south as Wilson's Promontory National Park according to Geoscience Australia. This event occurred several hours after  the M 4.0 in Florida. Like the event in Florida, this event in Australia is located near 103 degrees (102 degrees) from the M 7.1 in Xinjiang, China of January 22, 2024 and may have been promoted by energy from that source. The antipode of this epicenter is in the North Atlantic near the Azores, an active seismic area.

 

The last earthquake of M>=4.5 within about 200 km of this epicenter in Australia was an M 4.6 on July 20, 2012 - an aftershock of an M 5.4 on June 19, 2012. At the time this summary noted:

 

"NEIC reported an earthquake of M 4.5 in Victoria, Australia was felt with intensity IV in Moe-Uallourn, Morwell, Wodonga, Victoria and in Canberra, the Capital of Australia. It was also felt in Victoria with intensity II-III in the area(s) of Ararat, Bendigo, Craigieburn, Cranbourne, Crib Point, Echuca-Moama, Hastings, Healesville, Melbourne, Pakenham, Somerville, Sunbury, Traralgon, Warragul and Wonthaggi. Local news reported it is the strongest aftershock of the M 5.4 which hit the area a month ago on June 16 and was felt as far away as Melbourne several hundred km from the epicenter. In towns near Moe objects moved, and pictures, glassware and other unsecured objects fell. More than 200 aftershocks of the June event have been recorded." (July 20, 2012)

 

A small foreshock hit this area of Australia with M 3.3 on February 6, 2024 and was described at the time in this summary at the time as:

 

 

"An unusual earthquake of M 3.3 also lightly shock the area of Melbourne, Australia today. EMSC reported this earthquake of M 3.3 in SE Australia was felt with intensity up to III in the area(s) of SE Australia in Melbourne.  This epicenter is at 103 degrees from the Xinjiang, China earthquake of January 22, 2024, a distance at which a number of significant seismic events have been recorded since that time - including those of M 5.1 in Oklahoma and a series in Hawaii. A moderate earthquake may occur in this area of Australia in the next week, perhaps in conjunction with the new moon of February 9 as described in this summary:

 

"The new moon will arrive on February 9, 2024 at 22:59 UT.  Longitudes which are at local solar midnight at this time are located at about 15 East while those at local solar noon are near 165 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/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 full moon are considered  moderate high in the next week (February 4-14, 2024, February 6, 2024).

An unusual earthquake also occurred today in the South Pacific Ocean with M 4.9. This epicenter is within several hundred km of the M 7.1 in Xinjiang, China of January 22, 2024 and may have been promoted by focused seismic energy from that source. The actual antipode to this epicenter in the Pacific is near Hindu Kush, Afghanistan where several moderate earthquakes occurred today. A similar event of M 4.9 occurred two months ago on December 8, 2023. These appear to be aftershocks of an M 5.7 on July 10, 2023. At that time this summary noted:

 

 

"An earthquake of M 5.7 also occurred near local solar noon today in the Southern East Pacific Rise. It was not reported felt in this remote area. The last  earthquake within about 300 km of this epicenter with M>=5.7 occurred on M 5.8 on March 30, 2021 and M 5.7 on September 26, 2018." (July 10, 2023)

The strong swarm of moderate earthquakes continued today in the Gulf of California. The largest of today's events was an M 4.7 which occurred near local solar noon and may have been promoted by strong tidal stresses with the full moon of February 9, 2024. Strong activity in the Gulf of California often precedes significant activity in the area of southern California from areas southeast of Los Angeles to Los Angeles itself in the next week. In the previous issue of this summary this activity had been noted as:

 

 

"The strong swarm of moderate earthquakes in the Gulf of California continued at elevated levels today. The strongest events in today's series occurred near local solar noon and midnight and may have been promoted by strong tidal stresses which maximize near this hour. In the previous issue of this summary it had been noted as:

 

 

"A series of earthquakes in the Gulf of California continued today. This series has been ongoing for several days. These epicenters are located at the fourth node (90 degrees) from the M 7.6 in Honshu, Japan of January 1, 2024 and had been forecast at that time as:

 

 

"Far-field triggering is likely to occur with this earthquake in Japan. This is most likely at the following distances and areas:

 

90 degrees (node 4): Western Texas, Quebec, southern South Island, New Zealand, Gulf of California, Fiji" (January 1, 2024)

 

Forecasts 160245 and 160246 had expected this activity was likely in the Gulf of California around February 5-7. This epicenter is also at the fourth node from the Loyalty Islands event of M 7.1 of December 7, 2023 and was probably promoted by energy from that source. Other activity at this distance from the Loyalty Islands today occurred in Baja California, Vancouver ..." (February 6, 2024)

 

Forecasts 160245 and 160521 had expected this activity in the central Gulf of California was likely around February 7-13, 2024. This activity is at the fourth node (90 degrees) from the M 7.1 in the Loyalty Islands of December 7, 2023 and the M 7.6 in western Honshu, Japan of January 1, 2024 and at the seventh node (51 degrees) from the M 6.8 in Brazil of January 20, 2024 may have been promoted by energy from those sources."

A light earthquake of M 3.3 also occurred in Southern Texas today. NEIC reported this earthquake of M 3.3 in Southern Texas was felt with intensity up to IV in the area(s) of Southern Texas in Falls City. Light earthquakes in this region began  in late 2020. The largest earthquakes in the region in recent years were of M 3.9-4.0 on October 9, 2023 and September 14, 2023. Recent events in the area suggest triggering at this level in this area is likely at this time. Forecast 160252 had expected enhanced seismicity in this region was likely around February 7, 2024. This epicenter is located at 102 degrees from the Loyalty Islands M 7.1 of December 7, 2023 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.

UNUSUAL EARTHQUAKES SHAKE FLORIDA AND MELBOURNE, AUSTRALIA

 

EARTHQUAKE SUMMARY FOR FEBRUARY  7, 2024

 

 

An unusual earthquake occurred with M 4.0 today in the area east of Cape Canaveral, Florida. This earthquake which occurred near local solar midnight was probably felt in the area of Cape Canaveral but this was not immediately reported. The Miami Herald reported that more than 100 people reported feeling the quake to that source. It is possible this occurred with eruption of a methane clathrate as there are deposits of this chemical off the coast of Florida in this area. This epicenter is near 103 degrees from the M 7.1 in Xinjiang, China of January 22, 2024 and like recent unusual earthquakes in California, Hawaii and Oklahoma may have been promoted by energy from that source. No earthquakes of M>=4 have been recorded within about 200 km of today's epicenter in at least 35 years. The largest of those smaller events in the area occurred on June 18, July 16 and August 8, 2021 with M 3.9 each. These events were experimental explosions as noted in the June 18, 2021 report:

 

"An experimental explosion of M 3.9 off the coast of eastern Florida today was felt in Florida with intensity IV in Clemont and II-III in Ormond Beach, Cocoa, Jacksonville, Saint Johns and Opala." (June 18, 2021)

 

This suggests this may have been an artificial explosion. But previous such blasts have been done in the summer rather than in the winter and no agency has reported an explosion in the area at the time of today's earthquake. The only event of M>=3 in the region outside summer months occurred on February 22, 1992 with M 3.2.

 

Today's epicenter, in addition to being near 103 degrees from the Xinjiang, China quake of M 7.1 of January 22, 2024 is also at 145 degrees from the Banda Sea quake of November 8, 2022 and may have been promoted by energy from that source.

An earthquake of M 4.2-4.5 was widely felt today in the Melbourne area of Australia in the in the Gippsland region of Victoria. The quake centered near Leongatha and was felt as far north as Sunbury in Melbourne and as far south as Wilson's Promontory National Park according to Geoscience Australia. This event occurred several hours after  the M 4.0 in Florida. Like the event in Florida, this event in Australia is located near 103 degrees (102 degrees) from the M 7.1 in Xinjiang, China of January 22, 2024 and may have been promoted by energy from that source. The antipode of this epicenter is in the North Atlantic near the Azores, an active seismic area.

 

The last earthquake of M>=4.5 within about 200 km of this epicenter in Australia was an M 4.6 on July 20, 2012 - an aftershock of an M 5.4 on June 19, 2012. At the time this summary noted:

 

"NEIC reported an earthquake of M 4.5 in Victoria, Australia was felt with intensity IV in Moe-Uallourn, Morwell, Wodonga, Victoria and in Canberra, the Capital of Australia. It was also felt in Victoria with intensity II-III in the area(s) of Ararat, Bendigo, Craigieburn, Cranbourne, Crib Point, Echuca-Moama, Hastings, Healesville, Melbourne, Pakenham, Somerville, Sunbury, Traralgon, Warragul and Wonthaggi. Local news reported it is the strongest aftershock of the M 5.4 which hit the area a month ago on June 16 and was felt as far away as Melbourne several hundred km from the epicenter. In towns near Moe objects moved, and pictures, glassware and other unsecured objects fell. More than 200 aftershocks of the June event have been recorded." (July 20, 2012)

 

A small foreshock hit this area of Australia with M 3.3 on February 6, 2024 and was described at the time in this summary at the time as:

 

 

"An unusual earthquake of M 3.3 also lightly shock the area of Melbourne, Australia today. EMSC reported this earthquake of M 3.3 in SE Australia was felt with intensity up to III in the area(s) of SE Australia in Melbourne.

This epicenter is at 103 degrees from the Xinjiang, China earthquake of January 22, 2024, a distance at which a number of significant seismic events have been recorded since that time - including those of M 5.1 in Oklahoma and a series in Hawaii. A moderate earthquake may occur in this area of Australia in the next week, perhaps in conjunction with the new moon of February 9 as described in this summary:

 

"The new moon will arrive on February 9, 2024 at 22:59 UT.  Longitudes which are at local solar midnight at this time are located at about 15 East while those at local solar noon are near 165 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/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 full moon are considered  moderate high in the next week (February 4-14, 2024, February 6, 2024).

The strong swarm of moderate earthquakes in the Gulf of California continued at elevated levels today. The strongest events in today's series occurred near local solar noon and midnight and may have been promoted by strong tidal stresses which maximize near this hour. In the previous issue of this summary it had been noted as:

 

 

"A series of earthquakes in the Gulf of California continued today. This series has been ongoing for several days. These epicenters are located at the fourth node (90 degrees) from the M 7.6 in Honshu, Japan of January 1, 2024 and had been forecast at that time as:

 

 

"Far-field triggering is likely to occur with this earthquake in Japan. This is most likely at the following distances and areas:

 

90 degrees (node 4): Western Texas, Quebec, southern South Island, New Zealand, Gulf of California, Fiji" (January 1, 2024)

 

Forecasts 160245 and 160246 had expected this activity was likely in the Gulf of California around February 5-7. This epicenter is also at the fourth node from the Loyalty Islands event of M 7.1 of December 7, 2023 and was probably promoted by energy from that source. Other activity at this distance from the Loyalty Islands today occurred in Baja California, Vancouver ..." (February 6, 2024)

Forecasts 160245 and 160521 had expected this activity in the central Gulf of California was likely around February 7-13, 2024. This activity is at the fourth node (90 degrees) from the M 7.1 in the Loyalty Islands of December 7, 2023 and the M 7.6 in western Honshu, Japan of January 1, 2024 and at the seventh node (51 degrees) from the M 6.8 in Brazil of January 20, 2024 may have been promoted by energy from those sources.

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 QUAKE SHAKES EL SALVADOR

 

EARTHQUAKE SUMMARY FOR FEBRUARY  6, 2024

 

 

The strongest earthquake in the world today was an M 5.5 in El Salvador. NEIC reported it was felt with intensity up to IV in El Salvador at La Libertad. EMSC reported the mainshock was felt with light to moderate intensity in El Salvador at San Luis Talpa, Santa Tecla, Antigu Cuscatlan, San Salvador, Mejicano, Tonacatepeque, Apopa, Santa Ana, and in Guatemala at Residenciales Naciones Unidas, and Antigua among others. An aftershock of M 5.0 was felt in the same area as the mainshock. EMSC reported moderate to strong shaking in San Salvador and Santa Tecla, El Salvador.  The mainshock was followed by aftershocks of M 4.4 and M 5.0. The last earthquake of equal or larger magnitude in El Salvador was an M 6.5 on July 19, 2023 about 200 east of today's event and an M 5.7 within about 50 km of today's event on November 4, 2022. At that time this summary noted:

 

 

"A moderately large earthquake occurred south of El Salvador and Guatemala today. NEIC reported this earthquake was felt with intensity VI in El Salvador in Mejicanos, San Salvador; V in Sonsonate, Nueva San Salvador, Apopa, Chalchuapa, Santa Ana, III in La Libertad, Tonacatepeque, in Guatemala at Palin, Esciuntla, Santa Catarina, Guatemala City, Antigua Guatemala, San Antonio, Santa Cruz, Quetzaltenango and in Tegucigalpa, Honduras. An M 6.6 hit near this epicenter on May 30, 2019 and this may be an aftershock of that event. It is the strongest earthquake in the region off the coast of El Salvador since an M 5.9 on May 12, 2021. At the time this summary noted in this regard:

 

 

"A moderately strong earthquake occurred near El Salvador today with M 5.6. NEIC reported it was felt with maximum intensity VIII in El Salvador at Acajuatla; IV in Nuevo Cuscatlan, Antiguo Cuscatlan, and II-III in Opico, and in Guatemala at Masagua, Mixco, Guatemala City, Antigua Guatemala, Santa Catarina Pinula. This earthquake occurred within minutes of local solar midnight and was probably promoted by high tidal stresses which maximize near this hour. It is also near the maximum tidal longitude for the current new moon.

 

...

 

Today's event of M 5.9 is the strongest within about 200 km of this epicenter since an M 5.9 on December 19, 2019 and an M 5.9 on July 31, 2019. A strong M 6.6 hit the area about 100 km to the east on May 30, 2019." (May 13, 2021)

 

Today's event occurred as Hurricane Lisa was making landfall north of this epicenter in Guatemala." (November 4, 2022)

 

Forecasts 160232 and 160222 had expected today's event within about  150 km was likely around February 7, 2024. This activity is located at 104 degrees from the Loyalty Islands M 7.1 of December 7, 2023 and may have been promoted by energy from that source as discussed in the previous issue of this summary:

 

 

"A moderate earthquake also occurred today as an M 5.2 in the Loyalty Islands and New Caledonia. It was not reported felt in this remote area. The Loyalty Islands has been an active site of far-field seismic triggering since an M 7.1 on December 7, 2023 and has included activity at 144 degrees in the Reykjanes Ridge (see lead story in this issue); Italy and Austria, and at 103 degrees in Oklahoma, Louisiana, Xinjiang China and Guatemala among others."

A moderate earthquake of M 3.8 was felt with intensity up to III in Southern Idaho today. NEIC reported it was felt in Challis, Idaho. The mainshock was preceded near local solar midnight by foreshocks of M 2.0 and 2.3 and may have been promoted by strong tidal stresses which maximize at this time. The last earthquake of M>=3.8 in this region of Southern Idaho occurred on 3.9 on August 6, 2023 but the last of significantly larger magnitude in this region was an M 4.4 on September 8, 2020. At that time this summary noted:

 

 

"The strongest earthquake in the U.S. or Canada today was an M 4.4 in the southern Idaho aftershock zone. It and an M 3.9 foreshock were reported by NEIC to have been felt with intensity up to V in Idaho at Cascade and III-IV in Stanley, Lowman, McCall, Garden Valley, Ketchum, Challis, Ellis, New Meadows and Garden City. This is the strongest aftershock of the M 6.5 in southern Idaho of March 31, 2020 since an M 4.6 on June 25, 2020. Other aftershocks of M>=4.4 have hit the area on May 14 and May 21, 2020." (September 8, 2020)

 

Forecast 160334 had expected this event within about 50 km was likely around

February 7, 2024. This activity is at 103-104 degrees from the M 7.6 in Mindanao, Philippines of December 2, 2023 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.

QUIET GLOBAL SEISMICITY CONTINES

 

EARTHQUAKE SUMMARY FOR FEBRUARY  5, 2024

 

It was another relatively quiet day in global seismicity. The strongest earthquake in the world was an M 5.4 followed by a series of moderate aftershocks in the Reykjanes Ridge south of Iceland in the North Atlantic Ridge area. This is probably related to the recent volcanic eruptions in Iceland. The M 5.4 and aftershock of M 5.0 in the Reykjanes Ridge area occurred within minutes of local solar noon and may have been promoted by strong tidal stresses which maximize near this hour. A moderate series hit the area in December, 2023 about 150 km  northeast of today's epicenters and included several earthquake of M 5.0-5.3 but no events of larger size have hit within about 150 km of today's activity in the past three years. The last event of larger magnitude in the Reykjanes Ridge occurred more than a year ago on January 21, 2023. At the time this summary noted:

 

 

"The strongest earthquake in the world today was an M 5.7-5.8 in the Reykjanes Ridge region of the Northern Mid-Atlantic. It followed several foreshocks but was not reported felt in this remote oceanic area. This epicenter is about 300 km north of recent strong seismicity in the

Reykjanes Ridge and is probably separate from that swarm. These events occurred conjointly with the new moon (see above). Movements of magma associated with regional tidal stresses could have triggered this activity at this time. The last earthquake of M>=5.7 within about 200 km

 of today's epicenter occurred as an M 5.9 on September 10, 2017 and prior to that an M 5.7 on January 18, 2005 - only such regional events in the past 35 years." (January 21. 2023)

 

 

Forecast 160378 had expected today's activity in the Reykjanes Ridge about 150 km to the south was likely around February 4, 2024. These epicenters

are located at 104 degrees from the M 6.9 of November 24, 2023 in the Mariana Islands and may have been promoted by energy from that source.

An unusual pair of earthquakes also occurred today in the Southern Pacific Ocean both with M 4.8. They were not reported felt in this remote area.

It has been some time since a moderate earthquake hit this area. The last was an M 5.0 on March 8, 2018 and an M 5.2 on March 24, 2015 - the largest in the area in the past 35 years. These epicenters are at 145 degrees from the M 7.6 in  Western Honshu, Japan of January 1, 2024 and may have been promoted by energy from that source.

A series of earthquakes in the Gulf of California continued today.  This series has been ongoing for several days. These epicenters are located

at the fourth node (90 degrees) from the M 7.6 in Honshu, Japan of January 1, 2024 and had been forecast at that time as:

 

 

"Far-field triggering is likely to occur with this earthquake in Japan. This is most likely at the following distances and areas:

 

90 degrees (node 4): Western Texas, Quebec, southern South Island, New Zealand, Gulf of California, Fiji" (January 1, 2024)

 

Forecasts 160245 and 160246 had expected this activity was likely in the Gulf of California around February 5-7. This epicenter is also at the fourth

node from the Loyalty Islands event of M 7.1 of December 7, 2023 and was probably promoted by energy from that source. Other activity at this distance from the Loyalty Islands today occurred in Baja California, Vancouver

A moderate earthquake also occurred today as an M 5.2 in the Loyalty Islands and New Caledonia. It was not reported felt in this remote area.

The Loyalty Islands has been an active site of far-field seismic triggering since an M 7.1 on December 7, 2023 and has included activity at 144 degrees in

the Reykjanes Ridge (see lead story in this issue); Italy and Austria, and at 103 degrees in Oklahoma, Louisiana, Xinjiang China and Guatemala among others. Forecast 160422 had expected today's event within about 100 km was likely around February 3, 2024.

Several minor aftershocks of M 2.2 and M 2.3 followed a mainshock of M 3.6 in  Baja California today. They were lightly felt in the epicentral area.

NEIC reported this earthquake of M 3.8 in Baja California was felt with intensity up to IV in the area(s) of Baja California, Mexico at Puebla.

EMSC reported it was felt with light intensity at Conjuto Urbano Esperanza, Fraccionamiento 27 de Septiembre, and in Southern California at Calexico, Imperial, This area is near 103 degrees from the M 7.1 in Xinjiang, China earthquake of January 22 and may have been promoted by energy from that source. The M 3.6 occurred near local solar midnight and may have been promoted by strong tidal stresses which maximize near that hour. Forecast 160297 and 160295 had expected this activity was likely within about 25-50 km around February 5-7, 2024.

An unusual earthquake pair of M 2.3 and M 2.5 occurred in western Oklahoma today. NEIC reported these earthquakes of M 2.5 and M 2.5 in Oklahoma were felt with intensity up to IV in the area(s) of Oklahoma in Hinton and Prague. These epicenter are well to the west of much of the activity in Oklahoma in the past year. The last event within about 50 km of today's epicenter of equal or larger magnitude in this area was an M 2.6 on June 18, 2023. Forecast 160311 had expected today's activity was likely in early February. These epicenters are located at 103 degrees from the M 7.0 in Xinjiang, China of January 22, 2024 and was probably promoted by energy from that source.

An unusual earthquake of M 3.3 also lightly shock the area of Melbourne, Australia today. EMSC reported this earthquake of M 3.3 in SE Australia was felt with intensity up to III in the area(s) of SE Australia in Melbourne. This epicenter is at 103 degrees from the Xinjiang, China earthquake of January 22, 2024, a distance at which a number of significant seismic events have been recorded since that time - including those of M 5.1 in Oklahoma and a series in Hawaii. A moderate earthquake may occur in this area of Australia in the next week, perhaps in conjunction with the new moon of February 9 as described in this summary:

 

"The new moon will arrive on February 9, 2024 at 22:59 UT.  Longitudes which are at local solar midnight at this time are located at about 15 East while those at local solar noon are near 165 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/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 full moon are considered  moderate high in the next week (February 4-14, 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.
