February 2, 1995 Weekly Earthquake Report for Southern California ------------------------------------------------ January 26 - February 1, 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, January 26, Pacific Standard Time, to midnight Wednesday night, February 1, 1995, Pacific Standard Time. We recorded 265 earthquakes of M1.0 or larger during the 7-day period covered. It was a relatively quiet week, still dominated by the Northridge and Lander/Big Bear aftershock sequences. Only two events were reported as felt. The first felt quake was a M2.9 Northridge aftershock in the wee hours of Friday morning. The occurred at 5 am on Monday, in the Compton area, a M2.6. Isn't it nice that a random distribution of seismicity means that it is quiet sometimes? 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.
