WRIGHTWOOD, California — A small earthquake that occurred in Southern California was near the San Andreas Fault.
The U.S. Geological Survey says the 6:35 a.m. Friday quake had a magnitude of 3.5 and was centered 8 miles east-southeast of Wrightwood near the northeast end of the San Gabriel Mountains,
The area is about 50 miles east of downtown Los Angeles near Cajon Pass.
The temblor occurred at a depth of 7 miles and has been followed by several more tiny tremors just over magnitude 1.
California Institute of Technology seismologist Kate Hutton says the quake is too small to determine if it occurred on the San Andreas.
The region is moderately active. Since 2010, three other quakes measuring magnitude-3.5 or larger have hit within 15 miles of Friday's epicenter.
