4.2 earthquake hits Central California wilderness

A magnitude 4.2 earthquake was reported Sunday in a wilderness area of Central California.

The U.S. Geological Survey reported that the temblor occurred at 9:25 p.m. The epicenter was five miles northwest of Pinnacles and 13 miles northeast of Soledad.

The Pinnacles National Monument is a vast wilderness area containing a rock formation left by an extinct volcano. The San Andreas fault runs through the region and seismic activity is frequent.

There were no immediate reports of injury or damage.

Smaller quakes earlier Sunday shook parts of Los Angeles and Riverside counties.
