Northern California Seismicity Report for the week ending Nov 08, 2001

This report provides a brief summary of earthquake activity recorded by the U.S. Geological Survey Northern California Seismic Network in Menlo Park and the University of California Berkeley Seismological Laboratory. It is automatically generated each Wednesday shortly after midnight, Universal time (UT). UT (ie., Greenwich Mean Time) is 8 hours ahead of PST or 7 hours ahead of PDT.

Because it is not possible to review all of the earthquakes before this report is generated, it may contain errors. Please report errors or provide suggestions and comments to ncsn@andreas.wr.usgs.gov

The report no longer includes maps showing earthquakes for the entire US or world. Those maps are now available from the U.S.G.S. National Earthquake Information Center. In addition, all earthquake data can be retrieved from the Northern California Earthquake Data Center.

Please note that some of the earthquake data in this report have been reviewed by seismic analysts. Consequently, the parameters that describe the hypocenter, magnitude, origin time, and solution statistics may differ slightly from the information contained on the real-time earthquake web page. The differences reflect revised arrival times at seismic stations and the analysts' decisions to include or exclude information from seismic stations.

The minimum magnitude ( M) values in the following bullets reflect the smallest earthquake which the network can routinely record within the region. During the previous seven-day period ending at midnight (UT) Wednesday, our seismic networks recorded

• 24 M >2.0 earthquakes in Northern and Central California (map) (within dashed polygon of figure).

The largest event to occur this week in this region was a microearthquake of magnitude 2.8, 4 miles NNE of Coalinga, CA at 03:54 AM UTC Tuesday, 11 06, 2001 (07:54 PM PST Monday, Nov 05, 2001).

• 10 M >1.2 earthquakes in the San Francisco Bay area (map).

The largest event to occur this week in this region was a microearthquake of magnitude 2.1, 5 miles ENE of Yountville, CA at 06:49 PM UTC Wednesday, 11 07, 2001 (10:49 AM PST Wednesday, Nov 07, 2001).

• 18 M >1.2 earthquakes in the Long Valley region (map).

The largest event to occur this week in this region was an earthquake of magnitude 2.4, 14 miles S of Mammoth Lakes, CA at 07:30 AM UTC Thursday, 11 01, 2001 (11:30 PM PST Wednesday, Oct 31, 2001).

The following table provides a listing of all M >2 earthquakes that occurred this week. An explanation of the entries in the table is available.
