An earthquake with a magnitude of 4.1 rattled the Los Angeles area early Sunday afternoon.

According to the U.S. Geological Survey, the quake struck at 1:03 p.m. The epicenter was 11 kilometers (6.8 miles) southwest of Westlake Village, at a depth of 11.7 kilometers (about 7.2 miles).

Three other smaller quakes were detected near Malibu in the three minutes following the first one; they had magnitudes of 2.5, 3.0 and 2.8.

“The magnitude 4.1 was widely felt in the L.A. region,” USGS said on X.

There were no immediate reports of damage or injuries.

Thousands of earthquakes are recorded in California annually, but the vast majority are incredibly minor. Several hundred reach a magnitude of 3.0, and only about 15 to 20 reach a magnitude of 4.0 or greater, according to the USGS.   

In North America, only Alaska records more quakes per year than California. 

What to do in an earthquake

During an earthquake, knowing the proper steps to protect yourself and minimize injury is crucial. The California Department of Public Health (CDPH) provides detailed guidelines on what to do during such events. Here are the key points:

Drop, Cover, and Hold On:

Drop: Immediately drop down onto your hands and knees. This position prevents you from being knocked over and allows you to stay low and crawl to safety if necessary.

Cover: Use one arm to protect your head and neck, and if possible, take shelter under a sturdy table or desk. If no shelter is available, get down next to an interior wall away from windows. Stay on your knees and bend over to protect vital organs.

Hold On: Hold on to your shelter until the shaking stops. Be prepared to move with your shelter if it shifts.
