The island is owned by the Navy and is officially inhabited, though up to a few hundred people may be in residence at any time. It is 30 miles south of the tourist destination Catalina Island and 70 miles west of the San Diego County coast.

Wednesday morning’s large quakes were felt on the mainland, along the coast from Malibu to the Mexican border.

Also Wednesday, a 3.1-magnitude quake was recorded in Riverside County’s Jurupa Valley, which has been experiencing an earthquake “swarm.”

Since May 25, an area covering just a few square miles has recorded about 450 quakes. Most have been below magnitude 3. Wednesday’s 3.1 quake, at 5:20 p.m., drew 270 responses to the USGS “Did You Feel It” webpage. Most respondents were within 10 miles of the epicenter, in the Glen Avon neighborhood.
