Millions of sleeping Los Angeles-area residents were awakened early Thursday by a magnitude 4.2 earthquake at 4:29 a.m., the U.S. Geological Survey reported.
While the sharp jolt may have been scary for an area always warned of an upcoming “big one,” there were no reports of damage or injuries.
The temblor struck at a depth of 4.3 miles, its epicenter 1.4 miles north of the city of San Fernando, according to the U.S.G.S.
The quake was initially registered as a magnitude 4.3 quake but downgraded about 10 minutes later by the U.S.G.S. It was almost immediately followed by a magnitude 3-point-3 aftershock.
People in The San Fernando Valley, La Crescenta, Downtown Los Angeles, the Miracle Mile area, Hollywood, Pasadena and Marina del Rey reported feeling the quake.
The Los Angeles Fire Department said it immediately implemented its post-earthquake protocols, with fire department vehicles and helicopters patrolling its 470 square-mile jurisdiction to look for damages or residents experiencing emergencies. About 5:30 a.m., the department said it had completed its protocols.
“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.
The Los Angeles and Beverly Hills police departments reported normal operations, but both strongly encouraged residents to be prepared in the event of a major earthquake.
