Update from CNN:
A magnitude-5.8 earthquake has struck just east of Los Angeles, according to the U.S. Geological Survey. The quake's epicenter was about 2 miles southwest of Chino Hills and about 5 miles southeast of Diamond Bar, the USGS said.
The center was about 7.6 miles deep. In general, earthquakes centered
closer to the Earth's surface produce stronger shaking and can cause
more damage than those further underground.
A 5.8 magnitude
quake is considered by the USGS to be "moderate," which can cause
slight damage to buildings and others structures. About 500 can happen
globally each year, the survey says.
