LOS ANGELES -- A 5.1-magnitude earthquake hit the Los Angeles area Friday night, the USGS reported.
The epicenter was in Orange County near Fullerton, but it rattled residents in nearby areas as well, including Hollywood Hills.
The shaking could be felt for about 15 seconds.
The USGS had earlier reported it as a 5.4-magnitude, but later downgraded it to 5.1.
The epicenter of the temblor was one mile east of La Habra and four miles north of Fullerton, the U.S. Geological Survey said.
Firefighters in La Habra were urged to move to designated areas and initiate a survey of their districts.
"We have not heard of damage or injuries as of yet," Orange County Sheriff Lt. Paul Fuzzard said.
Hours before, a 3.6-magnitude tremor hit the same spot, according to the USGS.
Over a week ago, a 4.4-magnitude quake hit about 15 miles north of downtown Los Angeles at around dawn.
Friday's quake was stronger and shook longer.
Twenty years ago, a 6.7-magnitude killed 57 people in the greater Los Angeles area and caused $42 billion in damage.
