March 9, 1995 Weekly Earthquake Report for Southern California ------------------------------------------------ March 2 - 8, 1995 Prepared by: Kate Hutton, Seismological Laboratory (kate@bombay.gps.caltech.edu) Lucy Jones, U.S. Geological Survey California Institute of Technology For further information, please contact the authors or the Caltech Public Relations Office at 818-395-6326. For daily updates, call our Earthquake Information Hotline: 818-395-6977. -------------------------------- This week's Report covers the time period from midnight Thursday morning, March 2, Pacific Standard Time, to midnight Wednesday night, March 8, 1995, Pacific Standard Time. We recorded 244 earthquakes of M1.0 or larger during the 7-day period covered. We had a very quiet week this week. The only quake felt was a M3.0 in the northern part of the Northridge aftershock zone on Wednesday morning, which was slightly felt in the northern San Fernando Valley. The week's largest quake was a M3.4 just off of San Clemente Island last Thursday afternoon. We got no inquiries about it, since it was almost certainly not felt on the mainland. 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.
