A 3.5-magnitude earthquake rocked the South Los Angeles area Sunday night, hours after a smaller temblor struck, according to the U.S. Geological Survey.
The quake hit about 1 mile southeast of Baldwin Hills and View Park-Windsor Hills, and about 11 miles north of Torrance.
KTLA viewers reported feeling it in the San Fernando Valley, Hollywood and Westside areas.
The temblor was at a depth of about 6 miles, and located near the Newport-Inglewood fault, according to USGS seismologist Dr. Lucy Jones.
The Los Angeles Fire Department quickly went into “earthquake mode,” according to a tweet from fire Chief Terrazas.
The department previously described “earthquake mode” as dispatching firefighters from all 106 fire stations to “provide a complete and strategic survey of over 470-square miles in the greater Los Angeles area,” according to a department Facebook post on April 4.
The survey was completed by 10:10 p.m. and no damage was found, LAFD tweeted.

The quake struck hours after a 2.5-magnitude temblor that Jones described as a foreshock.
Every EQ has a 5% chance of being followed by a bigger EQ. Having a foreshock doesn't increase chance of being a foreshock.

That temblor hit about 1 mile southeast of Baldwin Hills, 2 miles northwest of Inglewood and 3 miles southeast of Culver City, USGS stated.
Although the quake was initially reported to be a 2.9, it was revised within minutes to a 2.5 magnitude. It was at a depth of about 4.1 miles.
Some speculated that the quakes occurred because of oil drilling in the Baldwin Hills area, but Jones tweeted that the quake struck “way below the oil fields.”
“The focal mechanism matches the Newport-Inglewood fault which was producing EQs long before we were pumping oil,” Jones tweeted.
In the hour after the larger quake, some 4,000 people reported feeling it, Jones tweeted.
Hundreds took to social media following the larger tremor:
