There were no immediate reports of injuries or structural damage within the City of Los Angeles.

A preliminary 4.5 magnitude earthquake struck Southern California on Friday night at approximately 11:38 p.m.

According to the official Twitter account for the U.S. Geological Survey (USGS), the quake targeted an area two miles west of El Monte and 10 miles from Los Angeles. Early results indicated "relatively deep depth" of 16.9 kilometers.

Following the quake, the Los Angeles Fire Department assessed the city for structural damage and issued a warning for residents in L.A. to prepare for aftershocks.

Early Saturday, an update from the USGS read, "Now that it's properly morning... Last night's M4.5 appears to be another of the deep, 'high stress drop' quakes that we sometimes see in the Los Angeles area. The 2008 M5.5 Chino Hills quake was another. These quakes typically have relatively strong shaking but few aftershocks."

Los Angeles Fire Department Chief Terrazas tweeted, "a preliminary survey has thankfully found no earthquake damage or injuries within the City of LA."

Residents are advised to visit the website of the Department of Homeland Security for information on how to prepare for natural disasters.
