4.6-Magnitude Earthquake Strikes Southern California

An earthquake centered several miles northwest of Malibu, Calif., rattled residents across the Los Angeles area on Friday, sparking a typical flurry of posts on social media, though the authorities said no major damage or injuries had been reported.

The quake had a preliminary magnitude of 4.6, according to the United States Geological Survey.

Residents across the county reported feeling a shake that lasted for about 10 seconds, with plates rattling in cupboards and plants swaying slightly.

Some residents, however, were surprised to learn of the earthquake and said they had not felt anything.

“We’ve gotten a few calls but there’s no structural damage being reported right now,” said Kaitlyn Aldana, a spokeswoman for the Los Angeles County Fire Department.

No significant damage was reported in the city of Los Angeles, according to Erik Scott, a spokesman for the Los Angeles Fire Department. Mr. Scott said the agency was in what it refers to as “earthquake mode.”

“When the ground shakes in the city of L.A., the L.A.F.D. enters this mode and firefighters from all 106 fire stations provide a complete survey of 470 square miles in greater Los Angeles to ensure safety,” he said.

Schools within the Los Angeles Unified School District sent out automated calls that noted students had remained in their classes.
