A 4.4-magnitude earthquake shook Southern California Monday morning.
"The tremor struck at 6:25 a.m. and the epicenter was in the Santa Monica Mountains between Westwood and Encino, closer to the Valley side, about five miles below the surface," Dr. Lucy Jones of the U.S. Geological Survey said.
Residents reported feeling the shaking from Los Angeles, Ventura, San Bernardino and Orange counties.
Monday's tremor was the largest earthquake in Los Angeles since the region stopped having aftershocks from the 1994 Northridge quake, Dr. Jones said.
The quake was initially measured at a 4.7-magnitude, but was downgraded minutes later by the USGS to a 4.4-magnitude.
The Los Angeles Fire Department was in earthquake emergency mode as crews surveyed the city by ground and air, however, there were no reports of any earthquake-related injuries or damage.
Dr. Jones said it was likely that the region would feel aftershocks throughout the day.
