A 5.2 magnitude earthquake shook Southern California on Monday, according to the U.S. Geological Survey.

The quake was centered in San Diego County but was felt as far north as Los Angeles.

No injuries or damage have been reported, according to Cal Fire San Diego.

The building “rocked for a long time,” said Greg Allen, a Washington resident visiting San Diego.

“Everything was moving, the blinds and everything,” he told ABC News. “Then we heard people going down the stairs. And since we’re from out of town, we figured we should probably leave the building also.”

California Gov. Gavin Newsom has been briefed and the state is coordinating with local authorities, according to the governor’s office.
