LOYALTY ISLAND SEE STRONG TIDAL TRIGGERING

 

EARTHQUAKE SUMMARY FOR OCTOBER 15, 2018

 

A series of strong earthquakes including those of M 6.6 and 6.3 among others occurred at local solar noon today. They were nearly sub-solar at the time of their occurrence, a time when tidal stresses from the sun are maximized and were probably triggered by these tidal stresses.

 

The last earthquake in the Loyalty Islands with M>=6.6 within about 250 km of today's epicenters occurred on August 29, 2018 with M 7.1. Today's earthquakes are probably aftershocks of that event. An M 7.0 also hit the region on November 19, 2017. Forecast 120645 had expected today's activity within about 50 km of these events was likely around October 20. These epicenters are at the seventh node  (51-52 degrees) from recent large earthquakes in Sulawesi and Lombok, Indonesia including the M 7.5 in Sulawesi of September 28 which is known to have killed more than 1000 people and may have been promoted from those sources.

Minor seismic events continued in northern Spain today in the region where  Hurricane Leslie hit two days ago. This is likely to continue for several more days with a moderate earthquake possible in this time. Forecasts 120360 and 120568 expected this activity was likely between October 11 and 18.

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.
