Caltech Staff Seismologist Jennifer Andrews has offered a more in-depth look at the earthquake that rocked Southen California on Thursday afternoon at approximately 12:30 p.m.

Andrews said the earthquake measured a magnitude 5.3, occurring about 25 kilometers south of Santa Cruz Island near the Channel Islands.

The offshore quake, felt in Pasadena and elsewhere in LA County, was 17 kilometers, and about 12-mile in depth, according to Andrews. She also said there wasn’t a particular fault that the quake could be tied to, but “there’s a number of faults segments in the Santa Cruz basin with this sort of right lateral strike-slip motion. So it belongs on one of those.”
