STRONG QUAKE SHAKES SOUTHERN MINDANAO, PHILIPPINES

 

EARTHQUAKE SUMMARY FOR JANUARY 21, 2021

 

 

The strongest earthquake in the world today was an M 7.0-7.1 south of Mindanao, Philippines. NEIC reported it was felt in the Southern Mindanao area with maximum intensity VI in Buayan and Katangawan; V in Mayo, Klinan, Padada, Baganga, Polomolok and Satorga and III in Pundaguitan. PHIVOLCS reported this earthquake at M 7.1 was felt with intensity V in Jose Abad Santos, Davao Occidental; Governor Generoso, Davao Oriental; Kiamba, Glan, Maitum and Malungon, Sarangani; Mailta, Davao Occidental; General Santos City; Rosario and Talacogon, Agusan Del Sur; Carmen and Lingig, Surigao Del Sur; Babini, Pantukan, Davao de Oro; IV in Mati City, Davao City; Cotabato City, Digos City; Sta Cruz, Davao del Sur, Alabel, Maasim and Malapatan, Sarangani; Tagum City, Davao Del Norte, Koronadal City, Tupi, Lake Sebu, Banga, and Polomolok, South Cotabato, Sta Maria, Davao Occidental, Bagumbayan, SultanKudarat; Maco, Maragusan, New Bataan, Compostels and Mawab, Davao de Oro; III ikn San Francisoc, Southern Leyte, Datu Blah T. Sainsuat, Maguindanao; Zamboanga City, Cagayan, De Oro City, Tandag City, and Cantilan, Surigao Del Sur, Sto Nino, South Cotabato, Bansalan, Davao Del Sur, Lambayong, Sultan Kudarat; Arakan, Cotabato and I-II as far as Surigao City, Philippines. This is the strongest earthquake in the world in nearly three months - after a similar M 7.0 in the Dodecanese Islands, Greece on October 30, 2020. This may have been promoted by strong tidal stresses associated with the last new moon as previously noted in this summary:

 

"The new moon will arrive at 05:00 UT on January 13. Longitudes which are at sub-lunar conditions (local solar midnight) at this time are near 75 West and those at sub-solar conditions (local solar noon) are near 105 East. These include in the west, the west coast of South America and eastern North America and in the east western and central Indonesia, the Philippines and Taiwan among others. These areas are most likely to see tidally enhanced seismicity in the next week through January 17, 2021. Tidal enhancement is most likely near local solar noon and midnight. A strong global earthquake is likely in this period." (January 12-18, 2021)

 

Today's event is the strongest within about 200 km of this epicenter since an

M 7.0 on December 29, 2018. The last of larger magnitude was an M 7.2 about 200 km southwest of this on February 11, 2009.  Forecast 130233 had expected today's event about 200 km to the southwest was likely around January 19 in the Mindanao area. The coast of California is near 103 degrees from the epicenter of this earthquake in the Philippines and may see enhanced seismicity related to incoming energy from this source in the near future.

An M 3.0 in the northern San Francisco area of California today was felt with intensity II-III at Concord, Pleasant Hill, Walnut Creek, Lafayette and Martinez, California according to NEIC. Forecast 130634 had expected this event within about 15 km was likely around January 24. This earthquake is at 103 degrees from the M 7.1 in Mindanao, Philippines, a distance where energy is concentrated on the surface after large earthquake. Subsequent seismicity is often enhanced at 103 degrees from large earthquakes. Watch for further enhancement in the area of Central and Northern California in the next week.

A strong swarm of minor earthquakes was felt in the Dominican Republic today. This contained at least a dozen event of M>=3. It may be related to the landfall of Tropical Storm 14S at the antipode in western Australia today as noted in this and previous summaries:

 

"Tropical cyclone 14S formed north of western Australia today with winds up to 50 kts. It is expected to make landfall today south of Broome, Australia. Some seismicity at the antipode near the Virgin Islands, Puerto Rico and the Dominican Republic, Caribbean may be triggered by antipodal energy concentration from this storm." (January 21, 2021)

 

Forecast 130298 had expected today's activity in the Dominican Republic was likely around January 19. This activity is also at 146 degrees from the M 7.0 in the Philippines and may have enhanced by energy from that source.

A pair of light but unusual earthquakes in Western Australia also accompanied landfall of TC 14S. These occurred as this storm passed over the epicenters and were probably triggered by stresses related to TC 14S. The last earthquake within about 200 km of today's M 3.4 with equal or greater magnitude was an M 4.4 on June 15, 2019 and prior to that an M 4.5 on June 19, 2017 and July 14, 2011. Forecast 130791 had expected regional enhancement in seismicity in later 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.
