AFTERSHOCKS CONTINUE IN LOTALTY ISLANDS; ALASKA

 

EARTHQUAKE SUMMARY FOR DECEMBER 6, 2018

 

 

The strongest earthquakes in the world today continued in the aftershock sequence in the Loyalty and New Caledonia Islands. These follow the mainshock of M 7.5 of December 5. The strongest today was an M 5.7 which occurred near local solar noon. It was nearly sub-solar as the new moon arrived and was probably promoted by energy from that tidal event as noted in previous issues of this summary:

 

"The new moon will arrive at 07:20 UT on December 7, 2018. Longitudes which are antisolar at this time are near 110 West while those sub-solar are near 70 East longitude. These longitude zones will experience the most tidal stresses possibly leading to moderate to strong triggered seismicity. In the west they include areas of western North America and the East Pacific Rise; in the east they include central Asia and portions of the Indian Ocean Ridge. Tidal promotion of seismicity however is not limited to these regions and may occur in areas near rupture. Watch for events occurring near local solar midnight and noon for possible targets of tidal triggering." (December 3-7, 2018)

 

Forecast 121918 had expected this activity in the Loyalty Islands was likely between December 5 and 9, 2018.

The strongest earthquakes in the U.S. or Canada today continued in the Anchorage, Alaska region as aftershocks of the M 7.0 of November 30, 2018. The largest today were M 4.7 and 4.1. These were felt with moderate intensity in the region of Southern Alaska around Anchorage. The sequence contained 7 events of M>=3 today and continued the decline noted in the past several days. Forecast 121886 had expected this activity around December 6.

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.

MODERATELY LARGE QUAKES IN LOMBOK, INDONESIA; CENTRAL CHILE

 

EARTHQUAKE SUMMARY FOR DECEMBER 5, 2018

 

A moderately large earthquake of M 5.5 occurred in Central Chile near Valpariso today. NEIC reported maximum shaking of intensity V in San Antonio, Quilpue, Vina del Mar, and Lampa with lesser shaking within about 100 km of the epicenter reported from Penaflor, Valparaiso, Villa Alemana, San Bernardo, Lampa and Santiago, Chile. This activity is located at 100-103 degrees from the Loyalty Islands where an M 7.6 occurred yesterday and an M 6.7 followed today. This is a distance at which strong triggering of seismicity can occur from concentrated refracted and reflected seismic energy off the core-mantle boundary and the Chile quakes were probably promoted from the Loyalty Islands. Other activity at this distance from the Loyalty Islands today in Peru, Chiapas, Mexico, Oklahoma, and Kyrgyzstan among others.

Aftershocks in the Anchorage, Alaska area continued to be felt lightly in the region today. The largest of these was an M 4.7 which was felt with moderate intensity in the Anchorage area. Only six aftershocks of M>=3 were recorded today as the aftershock sequence continues to decline. The rapid decline in aftershock events may be related to the cold ground temperatures which inhibit further ruptures. Forecast 121886 had expected today's activity in the Anchorage area within about 25 km of these epicenters.

There appeared to be some migration of the epicenters in the Anchorage area today. An M 3.9 occurred about 200 km to the east in Southern Alaska far from the aftershock zone. The last event of M>=3.9 within about 150 km of this epicenter was an M 4.3 on October 16, 2018. Stress redistribution after the Anchorage quake probably helped promote today's event to the east. The area may be near a stronger quake. Forecast 121885 had expected an event in this area was likely around December 8.

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.
