Chevron gas station in La HabraA 5.1-magnitude earthquake struck La Habra Friday night more than an hour after a smaller quake shook the area, according to the U.S. Geological Survey. The temblor, which had a depth of 4.6 miles, hit at 9:09 p.m. The epicenter was 1 mile east of La Habra, 1 mile west-northwest of Brea, 3 miles south-southwest of Rowland Heights and 4 miles north of Fullerton. Initially reported to be a magnitude-5.3, the quake was felt in Kern, San Bernardino, Orange, Ventura, Riverside, San Diego and Los Angeles counties. There were no reports of any injuries. About 40 aftershocks hit the Southland, including a 3.4-magnitude quake at 9:11 p.m. and a magnitude-3.6 at 9:30 p.m. “This earthquake is relatively close to the 2008 Chino Hills earthquake that was magnitude-5.4 that occurred about 5 miles to the southeast of this earthquake,” Caltech’s Robert Graves said.
