MODERATE QUAKE SHAKES GUAM

 

EARTHQUAKE SUMMARY FOR NOVEMBER 23, 2020

 

The strongest earthquake in the world today was an M 5.5 in the region of Guam.

NEIC reported this earthquake of M 5.4 in Guam was felt with intensity II-III in the area(s) of Guam th VI in Sinjana; IV in Tamuning, Barrigada, Hagatna and II-II in Yigo, Dededo, Asan, Yona, and Piti. Two earthquakes of M>=5.4 have occurred in the region near Guam in the past 1.4 years - an M 5.9 on June 23, 2020 and an M 5.4 on May 25, 2020. Today's earthquake was expected in forecast 128874 within about 100 km of this epicenter was likely around November 29. This epicenter is at 103 degrees from the M 7.0 in the Dodecanese Islands of October 30 and was probably promoted by strong concentrated energy from that source. Other earthquakes at this distance from the Dodecanese Islands today included quakes in Flores, Indonesia, Central and southern California, Nicaragua, Oaxaca, Mexico, Chiapas Mexico and Guatemala and in Antofagasta, Chile. These included most of the larger earthquakes in the world (M 4.5-4.9) today.

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.
