At 1:15 pm this afternoon, a M3.4 quake occurred 5 miles east of Carpinteria. We have no reports that it was felt, but it probably was. The focal mechanism was oblique thrust. Note that there have been a several quakes in the M2 range, at two different locations in southwestern Ventura Basin, in the past few days.

Immediately after the Carpinteria quake, at 1:29 pm, there was a M2.5 located 5 miles north of Anza. That one is less likely to have been felt.
