An earthquake measuring 3.8 in magnitude shook many residents out of their sleep in the Los Angeles area early Sunday morning.

The quake struck at 2:29 a.m. and was centered roughly 13 miles southwest of Malibu at a depth of 18 miles in the Pacific Ocean, according to the U.S. Geological Survey.

The preliminary magnitude was 4.1 but the temblor was quickly downgraded.

Shaking could be felt across Los Angeles County and areas of Ventura, Orange and Santa Barbara counties, according to a USGS map.

There were no reports of injuries or damage, and no indication that fire crews were concerned about infrastructure.

USGS said the earthquake was too small to trigger automatic cell phone alerts.

“We know some of you felt shaking and we hope you took a protective action like Drop, Cover, and Hold On,” officials tweeted.

Tens of thousands of earthquakes are recorded in California each year but the vast majority of them are extremely minor. Only several hundred are greater than magnitude 3.0, and only about 15 to 20 are greater than magnitude 4.0, according to the USGS

In the United States, only Alaska records more quakes per year than California.
