LOS ANGELES (AP) - More than 100 aftershocks have rattled Orange County south of Los Angeles where a magnitude-5.1 earthquake struck Friday.
The U.S. Geological Survey says the latest - a magnitude-3.4 - hit Saturday morning a mile from La Habra, about 20 miles south of Los Angeles.
Police in the nearby city of Fullerton say 20 apartment units and half a dozen homes were red-tagged, displacing 83 people.
Friday night's quake caused a rock slide, water main breaks and items to fall off shelves.
No serious injuries have been reported.
