A magnitude 6.3 earthquake off Baja California shook Southern California early Friday, the U.S. Geological Survey reported.
The temblor struck at 2:36 a.m. at a depth of 7 miles beneath the Pacific Ocean, about 163 miles south-southwest of Avalon in an area of shallow faulting where "the Pacific [tectonic] plate moves to the northwest with respect to the North America plate," according to a USGS statement.
It had been more than 40 years since an earthquake struck in that part of the ocean, according to the USGS.
The quake was felt over a wide area, from Ventura in the north to Ensenada in the south, as well as parts of San Diego and Orange counties, according to the USGS.
My husband felt it at work too.
