- --------------------------------
- This week's Report covers the time period from midnight Thursday
- morning, January 19, Pacific Standard Time, to midnight
- Wednesday night, January 25, 1995, Pacific Standard Time. We
- recorded 292 earthquakes of M1.0 or larger during the 7-day period
- covered.
- Although the overall number of earthquakes this week was
- not outstanding, people have been busy feeling them.
- The week's largest event was a M3.5 early Tuesday morning,
- about halfway between Riverside and Moreno Valley. It was felt,
- possibly as far away as Pasadena.
- Probably the second most excitement was due to the swarm
- of quakes north of Big Bear Lake beginning Saturday night and
- lasting into Monday. There were six of these that were felt (M2.8
- and larger); the largest one was M3.1. They were Landers/Big Bear
- aftershocks occurring geographically between the main aftershock
- zone of the summer of '92 and a M5.3 in November of '92.
- A very small quake (M2.4) on Saturday afternoon was felt
- in the La Cienega area, north of the I10 and southwest of the
- La Brea tar pits. It was not an aftershock.
- A M2.7 early Wednesday morning was an aftershock, however,
- of the Northridge quake. It was felt in the San Fernando area.
- 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.
