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.
