8 Aftershocks Logged Since Friday A.M. 5.2-Magnitude SoCal Earthquake

RIVERSIDE COUNTY, CA - Eight aftershocks were recorded since today's 5.2-magnitude earthquake hit Southern California shortly after 1 a.m., according to the U.S. Geological Survey. 

The 5.2-magnitude temblor struck about 13 miles north-northwest of Borrego Springs, the USGS said. The epicenter was 14 miles east of Anza, 15 miles northeast of Warner Springs and 42 miles from Escondido.

The shallow earthquake epicentered in Anza-Borrego Desert State Park at a depth of nine-tenths of a mile was felt in San Diego, Riverside, Orange, Los Angeles and Imperial counties, according to the USGS.

The aftershocks -- which are common following a quake, a seismologist noted -- were in the same general area. The strongest were magnitude-3.5 and -3.8 shakers.

"Every earthquake has a 5 percent of triggering an aftershock that is bigger than itself — always within a few miles of location of the first earthquake," seismologist Lucy Jones said.
