Weekly Earthquake Report for Southern California

--------------------------------
This week's Report covers the time period from midnight Thursday
morning, February 2, Pacific Standard Time, to midnight
Wednesday night, February 8, 1995, Pacific Standard Time. We
recorded 257 earthquakes of M1.0 or larger during the 7-day period
covered.
It was another quiet week, dominated by Landers/Big Bear
and Northridge aftershocks. As we predicted based on the mainshock
sizes, the Northridge aftershock sequence is decaying faster than
the Landers sequence is and is now at a lower overall level, in
spite of the fact that the Northridge quake happened more recently.
The largest event of the week happened to be a Northridge
aftershock M3.4 very early Wednesday morning. It was felt in
the northern San Fernando Valley. In Pasadena, it seems to have
been felt only by dogs, who proceded to wake everyone else up.
A M2.4 in the same area about two and a half hours earlier was felt
by a few people.
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.
