Magnitude 4+ earthquakes

Filed under: Uncategorized — kate @ 3:27 pm

There have been two magnitude 4.0+ earthquakes in the last two days, both of which were felt by the public.

First, at 2:45 pm yesterday (11/15), a 4.4 quake occurred offshore, 13 mi. ESE of San Nicolas Is., or 58 mi. WSW of Avalon.

At 1:21 pm today, a 4.6 quake occurred 16 miles SSE of Trona, or 23 mi. ESE of Ridgecrest. The location of this earthquake, the focal mechanism & the trend of the small aftershocks is consistent with the Garlock Fault. However, we cannot 100% sure of the fault attribution unless there is surface rupture (unlikely for a quake of this size).

Note: Due to high seismicity — and a low work staff — we were unable to complete the analysis of this week’s earthquakes. All earthquakes above magnitude 2.0 have been analyzed and so were most of the events smaller than this, but not all. We will update the following total as soon as we are able.

This report covers the seven day period ending 16:00 on November 05, 2009. During this period we detected and analyzed 550 earthquakes.
The table below lists the quakes during the past week that were M2.0 or larger in the central part of the coverage area. Times are local times; if you want Greenwich Mean Time, add 7 hrs to the Pacific Daylight Time or 8 hrs to the Pacific Standard Time listed.
