The U.S. Geological Survey says the magnitude 4.1 quake struck 8:07 a.m. Saturday. It was centered along the San Andreas Fault near Devore, in San Bernardino County. Some buildings swayed in downtown Los Angeles, about 60 miles to the west.
The Geological Survey says a small 2.0 magnitude aftershock hit about a half-mile away about two minutes later.
