--------------------------------
This week's Report covers the time period from midnight Thursday
morning, February 23, Pacific Standard Time, to midnight
Wednesday night, March 1, 1995, Pacific Standard Time. We
recorded 281 earthquakes of M1.0 or larger during the 7-day period
covered.
The largest quakes this week were also the most widely
felt. A pair of M3.7's occurred 20 seconds apart early Wednesday
morning, about 11 miles W of Palos Verdes Point. They were felt
in the South Bay and West L.A. areas, as well as San Fernando
Valley. They were followed by four aftershocks ranging from 2.0
to 2.8 within the next four minutes. As regular readers of this
Report know, the offshore region, known as the Continental
Borderland, is a fairly active area, so these quakes were no
surprise. They were not aftershocks of any previous quake.
Two quakes near Yucca Valley (a M3.2 and a M3.0) were felt
on Monday morning. These two were Landers aftershocks. Although
the two active aftershock zones, Northridge and Landers, are both
still very clear on the seismicity map, these two were the only
events this week of any significance.
Also, a small quake (M2.5) in the Santa Ana Mtns. was lightly
felt last night. Like the offshore quakes, it was part of our
routine seismic activity and not an aftershock.
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.
