Widespread shaking was reported Friday following a magnitude-4.2 earthquake in the mountains east of Los Angeles.
The quake was centered in the San Bernardino County community of Lytle Creek, located in the San Gabriel Mountains about 60 miles northeast of downtown Los Angeles. The quake was initially reported at magnitude-4.6, but later downgraded to 4.2
There were no immediate reports of damage or injuries.
Shaking was reported across a widespread area, including Long Beach, Carson, parts of the San Fernando Valley, Riverside, San Bernardino and portions of Orange County.
The quake was centered near where the San Andreas and San Jacinto earthquake faults come together.
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. The shaking knocked a radio station off the air and triggered mudslides and rockfalls that blocked roads.
The devastating magnitude-6.5 San Fernando Earthquake (aka Sylmar Earthquake) occurred five months later.
