4.2-magnitude earthquake hits Westwood

WESTWOOD VILLAGE, Calif. (KABC) -- A magnitude-4.2 earthquake struck 3 miles west-northwest of Westwood at 7:36 p.m. Sunday, according to the U.S. Geological Survey.

There were no initial reports of injuries or damage.

Eyewitness News viewers reported feeling the temblor in Calabasas, Tarzana, Sylmar, Manhattan Beach and Oxnard among other cities.

The earthquake was initially measured at a magnitude of 3.7 before being upgraded to a 3.8 and later a 4.2.

A second temblor with a preliminary magnitude of 1.8 happened about 6 miles north-northwest of Santa Monica at 7:45 p.m., according to the USGS.

Lucy Jones, a USGS seismologist, initially tweeted that the quake was probably an aftershock of a magnitude 4.4-temblor that struck southeast of Encino in the Santa Monica Mountains on March 17, but she later tweeted that Sunday's quake was too far away from the March quake's epicenter to be considered an aftershock.

Los Angeles Fire Department Spokesman Erik Scott said firefighters from all 106 fire stations conducted a damage survey of the department's 470-square-mile jurisdiction and found no significant damage.
