Noticed a little cluster of a dozen quakes, with a 3.9 and 3.8 about 1 minute apart down on the southern end of the Elsinore Fault Zone.

My WAG is due to the changed stress field from the El Mayor quake back in 2010.

Could it portend something more? Only time will tell. If the Elsinore lets loose I'll have a 2nd row seat (I'm about 6 miles away).
