Quake felt in San Diego area

Filed under: Felt Earthquakes — duty @ 12:15 am

At 11:53 pm Friday, there was a ML3.9 quake located just south of the U.S./Mexico border, 11 miles southeast of Chula Vista or 22 miles southeast of San Diego. Felt reports are coming into from the San Diego as far away as Valley Center & Temecula. Because it is in a different location, this quake is not an aftershock or a member of the Obsidian Butte sequence.

September 02, 2005

This report covers the seven day period ending 17:00 on September 01,2005. During this period we detected and analyzed** 545 earthquakes.
**This weekly report has events that have not been reviewed by a human. The actual number of events for the weekly total may change, as seismicity is higher than the analysts can keep up with, due to the Obsidian Butte Swarm. We apologize for any inconvenience this may cause. To view the SCSN Special Report for the Obsidian Butte Earthquake Swarm, click here.
The table below lists the quakes during the past 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.
