MODERATE EARTHQUAKE SHAKES MAUI, HAWAII

EARTHQUAKE SUMMARY FOR JANUARY 25, 2022

The strongest earthquake felt in the U.S. or Canada today was an M 4.7 in the region of Maui, Hawaii. NEIC reported it was widely felt with maximum intensity IV in Haiku, Kana, Makawao, Kula and III in Kihei, Pala, Kahului, Waikuku, Lahaima, and Hawi. The last earthquake in the Maui area of Hawaii within about 100 km of this epicenter of larger magnitude occurred on July 5, 2021 with M 5.2 and prior to that an M 4.8 on November 24, 2010. The largest event in the past 30 years in the area was an M 6.1 on October 15, 2006. Two earthquakes of M 4.7 occurred in February and March, 2017 in the area. This is not part of the current eruption of Kilauea but may bring increased seismicity to the big island of Hawaii and to that eruption. Today's even occurred within minutes of local solar midnight and was probably promoted by high tidal stresses which maximize near this hour. Forecast 140329 had expected this event in mid-January.

When the M 5.2 occurred on July 5, 2021 this summary noted:

"The last earthquake in the region of Hawaii of M>=5.2 occurred on April 14, 2019 more than two years ago with M 5.2-5.3. Similar earthquakes occurred with the eruption of the Spring and summer of 2018 which began with an M 6.9 about 100 km southeast of today's epicenter on May 4, 2018." (July 5-6, 2021)

Earthquakes of M 4.8 and 4.9 also occurred today in the Rat Islands, Aleutians, Alaska. They were not reported felt in this remote area. An M 5.2 hit this area of the Rat Islands on January 12, 2022. Today's activity is probably aftershocks of that event. Forecast 140713 had expected today's activity within about 50 km of these events was likely around January 29. These epicenters are at 103 degrees from the M 7.5 in Peru of November 28, 2021 and may have been promoted by energy from that source. The M 4.9 occurred within about an hour of local solar noon and may have been promoted by high tidal stresses.

The strongest earthquake in the world today was an M 5.3 in the South Sandwich Islands. It was not reported felt in this remote area and is aftershocks of an M 6.0 in the area yesterday. Forecast 140784 had expected today's event was likely within about 50 km around January 22. In the previous issue of this report the M 6.0 had been discussed as:

"The strongest earthquake in the world today was an M 6.0 in the South Sandwich Islands. NEIC reported it may have been lightly felt in Edinburgh Tristan da Cunha, Saint Helena. The M 6.0 was preceded by an M 5.1 southeast of today's epicenter. The M 6.0 is the strongest within about 100 km of this epicenter since an M 6.2 on February 16, 2015. An M 6.0 hit about 100 km southeast of today's epicenter on April 22, 2019. Forecast 140784 had expected today's activity was likely within about 50 km around January 22. This epicenter is at 143 degrees from the M 6.9 in Qinghai, China of January 7 and may have been promoted by energy from that source." (January 24-25, 2022)

Seismicity in Haiti continued today at elevated levels following deadly and damaging event of M 5.1 and 5.3 in the area yesterday. At the time this summary noted this as:

"Two moderate earthquakes shook Haiti today. These events of M 5.3 and 5.1 were followed by a series of lighter aftershocks. NEIC reported maximum intensity VII in Haiti at Asile, Grand Anse, Miragoane, Corail, and VI in Baraberes, Petit Goave, Camp-Perrin, V in Les Cayes Anse-a-Veau, Anse-a-Galets, Grand-Goave, Grand-Goave, IV in Port-au-Prince, Petit Trou-de-Nippes aned II-III in Carrfour, West Haiti and Pignon, North Haiti. At least two persons in Haiti were killed in the quakes by falling debris and landslides. More than 50 others were injured and hundreds of homes (about 200 destroyed) were 600 others damaged in the Nippes Department of Haiti. Further damage to buildings and additional landslides are expected in the next several days in the area.

...

The last earthquake of M>=5.3 within Haiti was an M 7.2 on August 14, 2021 followed by an M 5.8 on August 15. These may be aftershocks of the deadly event of M 7.0 on January 12, 2010, the last such events of this size in Haiti. Forecast 140581 had expected today's event was likely in this area around January 26. This epicenter is at the third node (120 degrees) from the M 6.9 in Qinghai, China of January 7 and may have been promoted by energy from that source." (January 24-25, 2022)

NEIC reported the earthquake of M 4.4 in Haiti was felt with intensity VII in the area(s) of Haiti at Mombin-Crochu. An earlier M 4.5 in Haiti today was felt lightly in Grand-Goave, Port-au-Prince, Petionville and Croix-des-Bouquets.

Several unusual earthquakes occurred today in or near East Africa today. These included an M 5.0 in the Congo (DR) and the Chagos Archipelago area of the Indian Ocean as well as an M 3.2 in Zimbabwe. The earthquake in DR Congo is the largest in that area within about 250 km of this epicenter since an M 5.0 on November 13, 2008. The last of larger magnitude in this area occurred more than 20 years ago. Most seismicity in this region occurs about 250-300 km northeast of today's epicenter with the last in that area of equal or greater magnitude an M 5.5 on September 9, 2019. Forecast 140276 had expected seismicity in this area was likely to be enhanced in mid-January, 2022. NEIC reported this earthquake of M 5.0 in DR Congo was felt with intensity IV in the area(s) of DR Congo in Manono, Katanga. This epicenter is located at 104 degrees from the M 7.5 in Peru of November 28, 2021 and may have been promoted by energy from that source. Other earthquakes today at this distance from Peru occurred as an M 4.8 and 4.9 in the Rat Islands; an M 4.8 in Fiji, and an M 3.2 in Zimbabwe.

The only other event reported by NEIC or EMSC in Zimbabwe in the past two years was a similar M 3.2 on January 14 near today's epicenter. At the time this summary noted this event as:

"A pair of light earthquakes occurred today in Southern Africa - an M 3.1 in

South Africa and an M 3.2 in Zimbabwe. NEIC did not report any felt effects with these events. The event in Zimbabwe was the strongest reported by NEIC since an M 4.5 on May 21, 2006, the only such event in the area within about 200 km in the past 30 years. Forecast 140500 had expected this region would see enhanced seismicity in mid-January. This epicenter is at 145 degrees from the M 6.8 in the Fox Islands of January 11 and was probably promoted by energy from that source." (January 14, 2022)

Forecast 140758 had expected enhanced seismicity in this area around January 28.

This epicenter is located at 145 degrees from the M 6.8 in the Fox Islands, Alaska of January 11, 2022 and, like the events in the Rat Islands, Alaska today at 103 degrees from the M 7.5 in Peru of November 28, 2021 and may have been promoted by energy from those sources.

The M 5.0 in the Chagos Archipelago was also at an unusual epicenter. The last earthquake within about 200 km of this epicenter with M>=5 was an M 5.0 on October 19, 2005, the only other such event in this area in the the past 30 years. An M 5.1 occurred about 250 km to the northwest of this epicenter on March 5, 2021. It was an aftershock of an M 6.1 which occurred August 31, 2020, the largest earthquake recorded within about 350 km of this epicenter in the past 30 years. This area became activity in July, 2020 after nearly 13 years of quiet at this magnitude level. Forecast 140542 had expected enhanced seismicity in this area in late January.

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.

EARTHQUAKES SHAKE NORTHERN AND SOUTHERN CARIBBEAN

EARTHQUAKE SUMMARY FOR JANUARY 24, 2022

Two moderate earthquakes shook Haiti today. These events of M 5.3 and 5.1 were followed by a series of lighter aftershocks. NEIC reported maximum intensity VII in Haiti at Asile, Grand Anse, Miragoane, Corail, and VI in Baraberes, Petit Goave, Camp-Perrin, V in Les Cayes Anse-a-Veau, Anse-a-Galets, Grand-Goave, Grand-Goave, IV in Port-au-Prince, Petit Trou-de-Nippes aned II-III in Carrfour, West Haiti and Pignon, North Haiti. At least two persons in Haiti were killed in the quakes by falling debris and landslides. More than 50 others were injured and hundreds of homes (about 200 destroyed) were 600 others damaged in the

Nippes Department of Haiti. Further damage to buildings and additional landslides are expected in the next several days in the area.

A smaller foreshock occurred in Haiti yesterday. This summary addressed this event at the time as:

"An earthquake of M 4.2 continued elevated seismicity in the region of Haiti today. This area was near local solar midnight when the M5.5 solar flare occurred on January 21 and is subject to seismic enhancement from SFE associated with that flare as noted in previous issues of this summary. More such activity is likely in the next several days in the areas of the Caribbean and Central America due to these effects.

"SWPC is expecting a proton storm associated with this flare may hit the earth on January 22-23 with 20% probability. This would be the first such proton storm of the new solar cycle and could affect global seismicity. Only two flares of larger size than M5.5 have been observed by SWPC in the past two years - an X1.0 on October 28, 2021 and an X1.5 on July 3, 2021. Both were associated with significant increases in global seismicity." (January 20-21, 2022)

"Areas which were at local solar noon were most at risk from this flare. These are between 80 and 100 East and West longitudes and include areas of Myanmar and Qinghai, China and Central America and northern South America." (January 22, 2022); (January 23-24, 2022)

An earthquake of M 5.3 was also felt in Trinidad and Tobago, Caribbean today. NEIC reported maximum intensity VI in Tabaquite and II-III in Sangre Grande and Tunapuna, Trinidad and Tobago with II in Mataruma, Guayana. While no damage has been reported with this earthquake some light damage is possible - perhaps from landslides. No tsunami threat exists with this earthquake. This is the strongest earthquake within about 200 km of this epicenter since an M 5.8 on July 3, 2008. Forecast 140324 had expected enhanced seismicity in the area to the west of this was likely in mid-January. This epicenter is near the antipode of the M 7.3 in Timor, Indonesia of December 14, 2021 and may have been promoted by energy from that source.

The strongest earthquake in the world today was an M 6.0 in the South Sandwich Islands. NEIC reported it may have been lightly felt in Edinburgh Tristan da Cunha, Saint Helena. The M 6.0 was preceded by an M 5.1 southeast of today's epicenter. The M 6.0 is the strongest within about 100 km of this epicenter since an M 6.2 on February 16, 2015. An M 6.0 hit about 100 km southeast of today's epicenter on April 22, 2019. Forecast 140784 had expected today's activity was likely within about 50 km around January 22. This epicenter is at 143 degrees from the M 6.9 in Qinghai, China of January 7 and may have been promoted by energy from that source.

An M 4.8 was felt widely in Western Australia today. NEIC reported intensity II-III for this event in Western Australia at Collie, Australind, Bunbury, Manduran, Busselton, Kwinana, Northam, Perth and Albany. Some minor damage to building walls and ceilings was reported by local and internet sources with the M 4.8. This follows a series of smaller events in the area in the past several days which have been followed in this summary for example as:

"A series of light earthquake including those of M 3.5, 3.6 and 3.9 lightly shook western Australia today. The M 3.9 is the largest within about 150 km of this epicenter since an M 4.2 on January 5, 2022 and prior to that an M 4.8 on October 9, 2007. Forecast 140767 had expected today's activity was likely in this area to the north of these epicenter at the end of January." (January 23, 2022)

The only earthquake within about 200 km of this epicenter with M>=4.8 in the past 30 years was an M 4.8 about 100 km southeast of this on October 9, 2007. Forecast 140767 had expected today's earthquake was likely at the end of January, 2020 within this area. This epicenter is at the seventh node (52 degrees) from the Vanuatu M 7.2 of October 2, 2021 and may have been promoted by energy from that source.

A moderate M 4.3 was also felt today in Morocco. NEIC reported it with maximum intensity VII in Morocco at Midelt, VI in Tahia, Azrou, and Fes and II in Sefrou, Morroco. Recent earthquakes of equal or larger size within about 200 km of this event in Morocco have most recently occurred as an M 4.3 about 200 km to the north west on July 1, 2020 and as an M 6.2 about 50 km to the south on November 17, 2019. Forecast 140624 had expected regional seismic enhancement in Morocco was likely around January 28.

EARTHQUAKES IN ALASKA; CARIBBEAN PROBABLY PROMOTED BY SFE

EARTHQUAKE SUMMARY FOR JANUARY 23, 2022

The strongest earthquake in the U.S. or Canada today was an M 5.0 in Unalaska, Alaska. NEIC reported it was felt with maximum intensity VI in Alaska in Dutch Harbor and V in Nikolski with III in Unalaska. An earlier event today of M 4.6 in the Fox Islands was reported with intensity II in Unalaska. These events appear to be aftershocks of the M 6.2 of January 22 at the same epicenter. At the time this summary noted in this regard:

"The strongest earthquake in the U.S. or Canada today occurred in the Unalaska - a community of about 4500 people in the area of the Fox Islands. NEIC reported this earthquake of M 6.2 was felt with maximum intensity IV in Unalaska and III in Dutch Harbor, Alaska. It was followed by an M 4.5 aftershocks about two minutes after the mainshock. This epicenter is about 100 km southeast of the M 6.8 and 6.5 of January 11, 2022 in the Fox Islands. It is probably a regional aftershock of those mainshocks. This is the strongest earthquake within about 100 km of the epicenter today since an M 6.2 on August 10, 2012. The only other events in this region in the past 30 years occurred on October 13, 2009 with M 6.4 and 6.5. Forecast 140458 had expected this enhanced seismicity in the Unimak Islands was likely around January 19." (January 21-22, 2022)

Forecast 140707 had expected enhanced seismicity in the Fox Islands within about

25 km of today's M 5.0 was likely around January 23.

An earthquake of M 4.2 continued elevated seismicity in the region of Haiti today. This area was near local solar midnight when the M5.5 solar flare occurred on January 21 and is subject to seismic enhancement from SFE associated with that flare as noted in previous issues of this summary. More such activity is likely in the next several days in the areas of the Caribbean and Central America due to these effects.

"SWPC is expecting a proton storm associated with this flare may hit the earth

on January 22-23 with 20% probability. This would be the first such proton storm of the new solar cycle and could affect global seismicity. Only two flares of larger size than M5.5 have been observed by SWPC in the past two years - an X1.0 on October 28, 2021 and an X1.5 on July 3, 2021. Both were associated with significant increases in global seismicity." (January 20-21, 2022)

A light earthquake of M 3.5 also occurred in the region of Puerto Rico today.

NEIC reported this earthquake of M 3.8 in Puerto Rico was felt with intensity II-III in the area(s) of Puerto Rico in San Antonio, Aguadilla, Rincon, Aguada, Adjuntas, Vega Alta, Isabela, Hatio, Arecibo and Utuaco. It had been expected in forecast 140580 to occur around January 26.

A major earthquake of M 7.2 hit Haiti on August 14, 2021, killing hundreds and causing major damage. The strongest aftershock of that event since August, 2021 occurred on January 11, 2022. This summary had noted that events as:

"Earthquakes of M 4.5 and 4.6 occurred in the region of Haiti today. NEIC reported it was felt with intensity III in Baraderes, Grand Anse, Haiti. This is the strongest activity within about 150 km of this in the region of Haiti since immediate aftershocks in mid-August, 2021 of the M 7.2 mainshock in Haiti of August 14, 2021. Today's events occurred near local solar midnight and may have been promoted by strong tidal stresses which maximize near this hour. Forecast 140056 had expected a moderate event in this area of Haiti was likely around January 8, 2022." (January 12, 2022)

Enhanced activity in Haiti was forecast in #140581 likely around January 26. This activity is at the third node (120 degrees) from the M 6.9 in Qinghai, China of January 7, 2020 and from the Vanuatu quake of M 7.2 of October 2, 2021 and may have been promoted by energy from those sources.

A series of moderate earthquakes also occurred in South Island, New Zealand today. GEONET reported an earthquake of M 4.3 was felt with weak intensity in the area southwest of Te Anau, South Island. 12 reports of felt intensity came from the area east and north of the epicenter. About 12 people reported weak shaking and 3 light intensity; 0 with moderate intensity and none with strong, 0 with severe and 0 with extreme shaking. This event occurred within about 10 minutes of local solar noon and was probably promoted by high tidal stresses which maximize near this hour. Forecast 140781 had expected enhanced seismicity within about 100 km of this epicenter was likely around January 22. These epicenters are at 102-104 degrees from the M 7.5 of November 28, 2021 and the Qinghai, China M 6.9 of January 7, 2022 and at 100 degrees from the M 6.8 in the Fox Islands, Aleutians of January 11 and was probably promoted by energy from those sources. Activity in southern and Baja California is also at this distance from Qinghai.

Moderate seismicity continued in the area of the volcanic eruption of January 15 in Tonga today. Earthquake of M 4.6 and 4.8 occurred near the volcano today. Aid has now reached Tonga and is being distributed and life is resuming there. A future large volcanic eruption is not anticipated while moderate seismicity continues in the area. This releases much of the pressure in the volcano. Forecast 140761 had expected moderate seismicity in this area of Tonga was likely around January 23.

MODERATE AFTERSHOCK IN QINGHAI, CHINA PROMOTED BY SFE

EARTHQUAKE SUMMARY FOR JANUARY 22, 2022

The strongest earthquake in the world today was an M 5.6 in the region of northern Qinghai, China. CENC reported this earthquake with M 5.8. It was followed by an aftershock of M 3.7-4.5. These may be regional aftershocks of the M 6.7 which hit the area on January 7 about 350 km southeast of this epicenter, but is not a classical aftershock of that event. The last earthquake of M>=5.6 within about 200 km of this epicenter with equal or greater magnitude was an M 6.3 about 200 km to the southwest of this on August 28, 2009. This event occurred at a longitude which was at local solar noon when the M5.5 solar flare occurred on January 21 and like a similar event in Myanmar yesterday was probably promoted by Solar Flare Effects (SFE) associated that solar flare. Forecast 140646 had expected today's event within about 50 km was likely at the end of January.

An unusual M 4.5 also occurred in the Bay of Bengal off Bangladesh today. Like the M 5.6-5.8 in Qinghai this epicenter is located at a longitude directly at noon when the M5.5 solar flare occurred on January 21. It is an unusual event. The only event with M>4.5 in the area within about 200 km of this epicenter in the past 30 years was an M 4.7 about 200 km northeast of this on July 27, 1996. An M 4.5 hit about 10 km east of this on December 8, 1992. Forecast 140559 had expected regional enhancement to seismicity was likely at the end of January.

An earthquake of M 4.7 was felt in the area of northwestern Turkey near Istanbul today. NEIC reported maximum intensity IV in Bursa, Turkey and III in Kirac, Istanbul. The last earthquake within about 150 km of this epicenter with M>=4.7 occurred more than two years ago on January 11, 2020 with M 4.9. An event of M 5.1 hit about 150 km southeast of this on August 31, 2021. This is near Istanbul, Turkey where a strong earthquake is considered by many local seismologists to be overdue. Forecast 140691 had expected today's activity within about 100 km was likely around January 25.

An earthquake of M 4.1 was also felt in the Dead Sea region of Jordan and Israel today. NEIC reported this earthquake of M 4.1 in the Dead Sea was felt with intensity III-IV in the area(s) of the Dead Sea in Tiberias and Bel She'an, Israel and in Jordan at Shooneh, Umm Qays, Kefar Tavor, Irbid and Aydun.

Like Istanbul, Turkey, some believe this area is overdue for a significant earthquake, possibly during the current solar active period. The Jordanian News service Petra reported up to 10 aftershocks in the area. The Israeli Geological Survey (GSI) issued a report today that Israel is probably not adequately prepared for a large earthquake and much damage and loss of life could occur in such an event. Tens of thousands could be killed in a massive earthquake on the African-Syrian Fault which runs through the area. The last earthquake within about 150 km of today's epicenter in the Dead Sea region of M>4.1 was an M 4.7 on July 4, 2018. Forecast 140340 had expected regional seismic enhancement in mid-January.

The strongest earthquake in the U.S. or Canada today was an M 4.3 in western Nevada near the California border. It was followed by a series of light aftershocks. NEIC reported this earthquake of M 4.3 in Nevada was felt with intensity II-III in the area(s) of Nevada at Luning, Hawthorne, and in California in Mammoth Lakes, Bridgeport, Coleville and Bishop. This is the strongest earthquake within about 100 km of this epicenter since an M 4.4 on March 30, 2021. More recent stronger events occurred as an M 6.0 about 100 km to the northwest of this on July 8, 2021 and about 100 km to the southeast with M 4.8 on January 6, 2022. Forecast 140605 had expected today's event within about 50 km was likely around January 26.

Moderate earthquakes also occurred in the West Chile Rise (M 5.3) and in the Ascension Island area of the Atlantic today. The event in the Atlantic was likely promoted by strong tidal stresses as it lies near the Greenwich Meridian which was expected to see enhanced seismicity with the full moon of January 17.

M5.5 SOLAR FLARE ENHANCES GLOBAL SEISMICITY

EARTHQUAKE SUMMARY FOR JANUARY 21, 2022

Global seismicity was up considerably in many areas today following the M5.5

solar flare yesterday. Large earthquakes today included an M 6.3-6.6 in Shikoku,

Japan; an M 6.2 in Unalaska, Alaska and an M 6.0 in southern Mindanao, Philippines. Moderately large earthquakes also shook the Russian Caucasus (M 4.2), central Mindanao (M 5.4), the Gulf of California (M 5.3); the Kermadec Islands (M 5.2) and Myanmar (M 5.3-5.4). As reported in the previous issue of this report the M5.5 flare occurred with the following parameters (SWPC):

#Event Begin Max End Obs Q Type Loc/Frq Particulars Reg#

#-------------------------------------------------------------------------------

2600 0541 0601 0612 M5.5 (January 20, 2022) 4.3E-02

"SWPC is expecting a proton storm associated with this flare may hit the earth

Areas which were at local solar noon were most at risk from this flare. These are between 80 and 100 East and West longitudes and include areas of Myanmar and Qinghai, China and Central America and northern South America.

The strongest of today's earthquakes - of M 6.3-6.6 shook the area of Shikoku, Japan today. NEIC reported maximum intensity VI in Miyazaki and Oita; V in Ehime, and Kumamoto Prefectures, Japan. Reuters reported this event injured more than 13 people and did considerable damage to buildings, water pipes and roads. Shaking with moderate intensity was reported in Oita and Miyazaki Prefectures with 5+ on the Japanese intensity scale (about VIII MMI). There was no reported damage to nuclear power plants in the area and no tsunami was reported. The last earthquake of M>=6.3 in Shikoku within about 200 km of this epicenter was an M 7.0 on April 15, 2016 and prior to that an M 6.6 on March 20, 2005. In the past 30 years the only similar activity in the area occurred in late 1996 with a series of events of M 6.6, 7.0 and 6.9. Aftershocks of M 4.6 and 4.9 were reported felt with intensity II-III in Yamguchi and Nagasaki (VI) Prefectures, Japan. Today's event occurred within about an hour of local solar midnight and may have been promoted by SFE as well as by high tidal stresses associated with the Full Moon of January 17 which maximize near this hour. Forecast 140361 had expected this activity within about 100 km was likely around January 17 in mid-January. This earthquake is located at 142 degrees from the M 7.5 in Peru of November 28, 2021 and may have been promoted by energy from that source. Like the M 6.4 in Talaud today, this epicenter is also located at the fifth node (72 degrees) from the M 6.8 in the Fox Islands, Aleutians, Alaska of January 11, 2022 and may have been promoted by energy from that source.

An earthquake of M 5.4 in Myanmar and India occurred today. NEIC reported this earthquake of M 5.4 in Myanmar/India was felt with intensity II-III in the area(s) of Myanmar with IV in Mawlaik, Sagaing and North Guwahati, Assam, India. Lesser shaking was felt in Mizoram, India, Bangladesh, Chattagan, Dacca, Tungi, Shahzadpur and Bogora, Bangladesh. It occurred at a longitude which was directly at local solar noon at the time of the M5.5 flare and was probably promoted by SFE. The only event of larger magnitude within about 200 km of this epicenter in the past year was an M 6.2 southwest of this epicenter on November 25, 2021 with M 6.2. Forecast 140332 had expected today's event within about 100 km was likely around January 19. Like the M 6.4 in Talaud today, and moderate quakes in Tonga this epicenter is also located near the fifth node (72 degrees) from the M 6.8 in the Fox Islands, Aleutians, Alaska of January 11, 2022 and may have been promoted by energy from that source.

The strongest earthquake in the U.S. or Canada today occurred in the Unalaska - a community of about 4500 people in the area of the Fox Islands. NEIC reported this earthquake of M 6.2 was felt with maximum intensity IV in Unalaska and III in Dutch Harbor, Alaska. It was followed by an M 4.5 aftershocks about two minutes after the mainshock. This epicenter is about 100 km southeast of the M 6.8 and 6.5 of January 11, 2022 in the Fox Islands. It is probably a regional aftershock of those mainshocks. This is the strongest earthquake within about 100 km of the epicenter today since an M 6.2 on August 10, 2012. The only other events in this region in the past 30 years occurred on October 13, 2009 with M 6.4 and 6.5. Forecast 140458 had expected this enhanced seismicity in the Unimak Islands was likely around January 19.

An earthquake of M 4.6 also occurred in the Kenai area of Southern Alaska today.

While it is about 100 km to the west of M 5.1 in that area which occurred on

January 21 it is probably a regional aftershock of that event which was noted in this summary as:

"The strongest earthquake in the U.S. or Canada today was an M 5.1 southwest of Anchorage, Alaska in southern Alaska. NEIC reported maximum intensity V in the West Kenai Peninsula and IV in Clam Gulch, Kasilof, Homer, Anchorage, Borough and Ninilchik with lesser shaking of II-III in Anchor Point, Soldotna, Sterling, and Kenai among others. This is the strongest earthquake within about 150 km of this epicenter in Southern Alaska since an M 5.9 about 100 km southwest of this on December 21, 2021 and prior to that an M 5.7 on November 21, 2018. Forecast 140463 had expected today's event was likely within about 50 km of this epicenter around January 20." (January 20-21, 2022)

An M 6.0 also shook the region of Southern Mindanao, Philippines today. NEIC reported intensity II-III in Glan and Buayan, Southern Mindanao for this event.

BMG reported this earthquake with M 6.1 was felt with intensity III-IV in Melonguane, Indonesia. PHIVOLCS also reported M 6.1 and felt effects of III in Sarangani, Davao Occidental; Glan, Sarangani; II in Malapatan, Sarangani and I in Lebak, Sultan Kudarat; General Santos City. It occurred near local solar noon and may have been promoted by high tidal stresses which maximize near this hour. The last earthquake within about 200 km of this epicenter occurred as an M 6.1 on July 10, 2021 and prior to that an M 6.6 on January 6, 2019. This earthquake occurred within about an hour of local solar noon and was probably promoted by SFE and/or by strong tidal stresses which maximize near this hour. Forecasts 140265 and 140531 had expected enhanced activity in this area was likely between January 17 and 23. Like a series of earthquakes in Tonga today, this epicenter is located at the fifth node (72 degrees) from the M 6.8 in the Fox Islands, Aleutians, Alaska and may have been promoted by energy from that source.

The earthquake in the Gulf of California today of M 5.3 was followed by a series of moderate aftershocks. NEIC reported this earthquake of M 5.3 in the Gulf of California was felt with maximum intensity IV in Santa Rosalia and Hermosillo, Sonora, Mexico. An aftershock of M 4.4 was felt with intensity II-III in the area(s) of Baja California at Loreto and VI in Santa Rosalia. This area has been moderately active in the past week and was near local solar midnight at the time of the M5.5 flare. The event occurred near local solar noon and may have been promoted by SFE and/or strong tidal stresses. Forecasts 140328 and 140587 had expected enhanced seismicity within about 150 km of this epicenter in the Gulf of California was likely between January 19 and 27. This epicenter is at the third node (120 degrees) from the Flores and Timor earthquake of late December, 2021 and may have been promoted by energy from those sources.

The M 5.2 in the Kermadec Islands today was not felt in that remote area. It and other seismicity near the past several days near the International Date Line (IDL) have been promoted by high tidal stresses associated with the full moon of January 17 as noted in previous summaries as:

"The full moon arrived on January 17, 2022 at 23:49 UT. Longitudes which were at local solar noon at this time are near 180E/W longitude while those at local solar midnight are near 0E/W. These are the most likely longitudes to see tidal triggering during the next week and include area of western Europe in the east and the Aleutians and Tonga/Fiji/New Zealand in the west. A strong earthquake appears likely in one or more of these areas between January 13 an 22." (January 14-19, 2022),

Forecasts 140764 and 140497 had expected this activity within about 100 km was likely in mid-January.

While moderate earthquakes continued near the Volcanic epicenter in Tonga of January 15, consequences of that eruption continued to be felt far away. A major oil spill affecting 21 beaches and many animals along the coast of Peru may have been caused by tsunami waves from the eruption which reached nearly 2 meters (6.5 feet) in Peru and did considerable damage to coastal facilities. Runways in Tonga have largely been cleared of ash and debris and the first supply planes arrived in that area today. The Tonga government reported that the eruption and tsunami adversely affected about 85% of the country's more than 100,000 residents. One fact about the eruption of Hunga-Tonga which has not been widely reported is that when the volcano began unrest in late December, 2021, the Tonga Geological Survey issued a daily warning of a possible eruption and associated tsunami. This warning alerted local Tongans so that when the eruption began many took to their cars and vehicles to evacuate to higher elevations before the tsunami arrived. This led to massive traffic congestion but also prevented many losses due to the tsunami. Traffic congestion was complicated by ash fall from the eruption and the need to cover the mouth from the falling ash. Moderate earthquakes of M 4.7, 4.8 and 4.8 occurred near the volcano today. Forecast 140503 had expected activity in this area would be enhanced around January 18.

An M 4.2 was also felt widely in the Russian Caucasus today. NEIC reported maximum intensity VI in Dagestan, Russia at Sulak and Pervomayskoye, V in Karabudakhkent, Babayurt, IV in Leninkent, and II-III shaking in Kizlyan, Staraja, Kurakin, and in Kazaksstan with this earthquake. Forecast 140664 had expected enhanced seismicity in this area was likely at the end of January.

A light M 1.9-2.0 earthquake also occurred in Northern South Carolina today. This continues a series of light earthquakes in the area over the past two months. Today's event may have been promoted by a strong winter storm which hit the area about the same time as this earthquake occurred. The storm impacted much of the southeastern U.S. and included major snow and ice fall in the region. Forecasts 140390 and 140650 had expected this event in South Carolina was likely in mid-January. Like earthquakes in Oaxaca and Chiapas, Mexico this epicenter is at 143 degrees from the Flores and Timor earthquake of late December, 2021 and may have been promoted by energy from that source.
