There are no reports of damage from a late-night moderate earthquake felt throughout the greater Los Angeles area.
The U.S. Geological Survey says the magnitude-4.4 quake struck at 11:23 p.m. Tuesday and was centered two miles east of Yorba Linda in northern Orange County. There was a magnitude-2.7 aftershock about a minute later.
The quake was felt throughout the Los Angeles area, including the San Fernando Valley some 50 miles from the epicenter.
Los Angeles firefighters found no damage after a citywide assessment completed early Wednesday. The epicenter is about 35 miles southeast of downtown Los Angeles.
Authorities in Orange and Los Angeles counties say there are no reports of injuries.
