A magnitude-4.2 earthquake in mountains east of Los Angeles shakes parts of Southern California
Many areas in Southern California are rocked by an earthquake that occurred in the mountains east of Los Angeles.
The epicenter of the earthquake is Lytle Creek, a locality in San Bernardino County, which is situated 60 miles northeast of downtown Los Angeles in the San Gabriel Mountains. The quake was initially reported at magnitude 4.6, but later downgraded to 4.2
Shaking was reported across a wide area, including Long Beach, Carson, parts of the San Fernando Valley, Riverside, San Bernardino, and portions of Orange County. The quake was centered near the center of the San Andreas and San Jacinto earthquake faults. There were no instant reports of harm or accidents.
The area was the site of a magnitude-5.2 earthquake in 1970. The main quake came 20 minutes after a magnitude-4.1 foreshock. Roads were blocked by mudslides and rockfalls caused by the tremor, which also forced a radio station to go off the air.
The devastating magnitude-6.5 San Fernando Earthquake (aka Sylmar Earthquake) occurred five months later.
