I’m sure that you (in southern Cal) did not feel it, but there was a ML4.0 near the Pinnacles, 22 miles south-southeast of Hollister, at 9:30 pm on Sunday. This is the area where the Calaveras fault & the San Andreas fault diverge.
Also, there was a M5.1 at 10:35 pm last night offshore of Baja California, Mexico, about 160 miles south of Ensenada. This epicenter & magnitude come from the National Earthquake Information Center.

Saturday’s Baja quake had a ML3.1 aftershock last night at 7:58 pm. There was also a ML2.9 quake in Baja, Mexico, at a different location 44 miles south of Ocotillo. The time for that quake was 7:17 pm. We have no reports that either of these quakes was felt.
What was felt, however, was a small (ML1.8) quake in the Hollywood Hills 1 mile south-southeast of Studio City. It occurred just before 3:36 am. We have a small handful of felt reports from West Hollywood & Studio City.

We now have several reports that Saturday’s Baja quake was felt in the southern Imperial Valley, particularly El Centro and Mexicali.
On Sunday at 5:19 pm, there was also a felt earthquake, in the Oxnard area. The epicenter was located 2 miles south-southeast of Port Hueneme, or 4 miles south of Oxnard. Quite a few people along the coast from Ventura to Malibu, and inland to Westlake Village, Thousand Oaks, etc., felt it. The magnitude was ML3.1. There have been 2 aftershocks, the largest of which was a ML2.5 at 5:38 pm.
Early this morning, there was a Hector Mines aftershock (of the 1999 Mw7.1 quake), located 12 miles west-southwest of Ludlow. The time was 6:22 am. The magnitude was ML3.2, plenty large enough to feel, but we have no reports so far, probably due to the sparse population in the area.

Southern California has had another M3+ quake this afternoon: a ML3.2 19 miles north-northwest of Goldstone Lake, or 35 miles east of Ridgecrest. This is an unpopulated area in the northern Mojave desert, near the Garlock fault.
There has also been a ML4.0 San Simeon aftershock, 5 miles east-northeast of San Simeon, at 5:40 pm, felt by a few people.
