LOS ANGELES — An earthquake and a series of aftershocks shook Los Angeles early Thursday morning, waking some residents of California’s largest city.

The quake struck near Pacoima in L.A.’s San Fernando Valley around 4:30 a.m., with a preliminary magnitude of 4.2, according to the U.S. Geological Survey.

Residents from across the valley to downtown L.A., beach cities, Hollywood and Pasadena reported feeling the quake. Shaking was felt as far away as Lake Forest in Orange County and Rancho Cucamonga in San Bernardino County, KTLA reports.

In the following half-hour, USGS recorded aftershocks with magnitudes of 3.3, 2.4 and 2.1. A stronger aftershock hit shortly before 6:50. a.m.

The Los Angeles Fire Department said it carried out its typical post-earthquake protocols, with vehicles and helicopters patrolling its 470 square-mile jurisdiction to look for damage or residents experiencing emergencies. About 5:30 a.m., the department said it had completed the process.

“The LAFD has concluded the systematic survey of the City of Los Angeles by ground and air, and is pleased to report that no major infrastructure damage was noted by our personnel in the City of Los Angeles, and that there has been no loss of life or serious injury that we can directly attribute to the (magnitude) 4.2 earthquake,” spokesman Nicholas Prange said.
