SOUTHERN CALIFORNIA SEISMOGRAPHIC NETWORK A Cooperative Project of Caltech and the U.S. Geological Survey October 3, 1996 Weekly Earthquake Report for Southern California ------------------------------------------------ September 25 - October 2, 1996 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 818-395-6327. For daily updates, call our Earthquake Information Hotline: 818-395-6977. -------------------------------- This week's Report covers the time period from midnight Thursday morning, September 26, Universal Time (ie. GMT), to midnight Wednesday night, October 2, Universal Time. In local time, the period of coverage is from 5 p.m., September 25, Pacific Daylight Time, to 5 p.m., October 2, Pacific Daylight Time. Because of some computer system problems, we haven't been able to process our data into its final form. Therefore, this Weekly Report consists of the automatic locations and magnitudes, the same ones you would find on CUBE or with the "finger quake" utility. Next week, when we hopefully have all the data processed, we will provide a summary of the final seismicity data for the whole two-week time period. Fortunately, the seismicity has been low and no-one felt any earthquakes. Table 1 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.
