MARINA DEL REY, Calif.—An early morning jolt has struck Southern California.

The U.S. Geological Survey says an earthquake with a 3.8-magnitude rattled the greater Los Angeles area at 3:18 a.m. local time. The temblor was located 2 miles east south east of Marina del Rey.

A dispatcher with the Los Angeles County Sheriff's Department said it "wasn't much of a quake" and that he hasn't had any calls from the public about it.

Within half an hour of the quake hitting, dozens of people had reported feeling the shaking on the USGS website, including some as far away as Riverside.
