STRONG EARTHQUAKE SHAKES MINDANAO, PHILIPPINES

 

EARTHQUAKE SUMMARY FOR OCTOBER 16, 2019

 

The strongest earthquake in the world today was an M 6.4 in southern Mindanao, Philippines. NEIC reported it was felt with maximum intensity VII in Southern Mindanao at Koronadal, Kidapawan andDigos; VI in Columbio, Tulunan, and Kabacan; V in Tacurong ad Sulit and IV in Bagontapay and Kalawag among others. An aftershock of M 5.0 was felt in Buayan Southern Mindanao with intensity III. A regional aftershock of M 5.1 was felt with intensity IV in Mindanao at Mabantao and Davao and III in Ula, Philippines. This is the strongest earthquake in the world since an M 6.8 on September 29, 2019. Only four such quakes have occurred in the past 2.5 months - in Seram, Indonesia on September 25 (M 6.5); Tonga on September 1 (M 6.6) and the South Sandwich Islands on August 27 (M 6.6). It is also the strongest in the region of Mindanao, Philippines since an M 7.0 on December 29, 2018 and prior to that an M 6.9 on April 28, 2017. These followed a regional quiet period from July 2010 after an M 7.6 hit the area. Forecast 119214 had expected today's activity within about 100 km was likely

between October 13 and 17. The activation of the San Francisco Bay area, California is at 103 degrees from this event in Mindanao and some linkage is possible between the two areas.

The strongest earthquakes in the U.S. or Canada today occurred in the Kodiak Island region of Alaska. The last earthquakes of M>=3.6 in the Kodiak Island region within about 100 km of these epicenters occurred October 14, 2019 with M 4.0 and today's events are probably aftershocks of that. These events of M 3.5 and 3.6 were considered likely to the south of these epicenters in forecast 119392 around October 14.

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.
