A 6.4 magnitude earthquake struck Southern California on Thursday, the largest temblor to hit the region in decades.

The 10:33 a.m. quake was centered in the Searles Valley, a remote area of Kern County about 100 miles from Los Angeles.

The quake was the largest in Southern California since the 1994 6.6 Northridge quake, which killed dozens and caused billions of dollars in damage. But the Northridge quake hit in the center of a populated area, while Thursday’s quake was located far from the metropolitan Los Angeles area.

It was not immediately clear whether anyone was injured in the quake, which struck the Los Angeles area shortly after 1 p.m. EST. Its epicenter was located in the desert about 20 miles east of Indian Wells, Calif., far away from major population centers, said Paul Caruso, a geophysicist with the United States Geological Survey.

Felt in Las Vegas

Trona, an unincorporated community in San Bernadino County, “sustained varying degrees of damage” but no injuries have been reported, according to San Bernadino County Fire’s verified Twitter account.
The department reported “minor cracks (in buildings); broken water mains; power lines down; rock slides on certain roads” in northwestern communities in the county.
The epicenter was about 60 miles north-northwest of Barstow.
The National Weather Service tweeted that the earthquake was felt in Las Vegas, adding, “so far no significant damage reports.”
A tsunami is not expected, according to the National Tsunami Warning Center.
There have been at least 25 aftershocks, according to USGS research geophysicist William Yeck.
He was called into work at the agency’s office in Golden, Colorado. “We’re getting calls off the hook,” he said.
