A morning earthquake was felt from the San Diego area to the San Fernando Valley, but it did little harm.
The magnitude-4.7 jolt hit in Riverside County at 10:29 a.m. and was centered near the city of Lake Elsinore about 50 miles southeast of Los Angeles near the Orange County Line according to the U.S. Geological Survey.
Some store shelves were shaken empty and some swimming pools
were cracked in Lake Elsinore.
The quake struck under the Santa Ana Mountains in a remote area of the Cleveland National Forest along a well-known fault that runs from Mexico to Los Angeles.
Many aftershocks followed in the next few hours, as big as magnitude-2.5.
