LOS ANGELES - Authorities say a magnitude-5.1 earthquake has shaken the Los Angeles area.
The U.S. Geological Survey originally estimated the quake to be a magnitude-5.3. It said the Friday quake struck at about 9:11 p.m. and was centered near Brea in Orange County - about 20 miles southeast of downtown Los Angeles.
About an hour earlier, a 3.6 quake hit nearby in the city of La Habra.
There were no immediate reports of damage.
