The Weekly Report is being issued one day early because of the Thanksgiving holiday. We detected and processed 466 earthquakes during the 6-day period covered. Seismicity has declined a bit, and it was a short "week". The largest event inside the main body of our coverage area was a M2.6 on Saturday morning along the Elsinore fault zone, north of the U.S./Mexico border. There were no quakes above M3 and there were no quakes felt. Have a happy Thanksgiving. The table lists the quakes this 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. Table 1 ------- Date Time N Lat. W Long.
