Not exactly in Southern California, but felt by quite a few here - mostly in Imperial and San Diego Counties - a M5.2 earthquake occurred in Baja California at 11:32 am today. Locally referenced it was located 29 miles south-southeast of Calexico, California. The focal mechanism for the event shows strike-slip movement along the fault. Also interesting to mention, this is the largest sized earthquake "we've" had in that area since 1987 when there was a M5.4. Regarding today's earthquake we've had, so far, one M4.1 aftershock (at 12:33 pm) and about a dozen greater or equal to M3.0. As of yet, I have received no reports of the M4.1 being felt.
