A 5.2 earthquake rattled San Diego, California and the surrounding area on Monday afternoon, according to the US Geological Survey.
The quake struck at 10:08 local time (18:00 GMT) with an epicentre in Julian, California.
California Governor Gavin Newsom’s office posted on X shortly after the quake that he had been briefed on the situation.
“The state is co-ordinating with local authorities to assess any damage and if emergency response is needed,” the statement said.
The San Diego sheriff’s office said in a statement about an hour after the quake that they had not yet “received any reports of injuries or major damage caused by the earthquake,” with the caveat that it was a “developing situation”.
In the moments before it struck, emergency alerts ordered residents to take shelter as far away as Los Angeles.
“Drop, cover, hold on. Protect yourself,” the alert read.
Julian, a resort town, is located in the Cuyamaca Mountains about an hour north-east of the coastal city of San Diego.
The National Weather Service said a tsunami was not expected.
The USGS continued to report smaller aftershocks in the region in the hour after the quake.
