- --------------------------------
- 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.
