SOUTH EL MONTE (CBSLA) — A 4.5-magnitude earthquake struck the Los Angeles area late Friday night, the U.S. Geological Survey reported.

The quake was centered less than two miles west-southwest of South El Monte and occurred at 11:38 p.m. Several aftershocks occurred across the Los Angeles Basin shortly afterward.

The focal point of the earthquake was almost the same location as the M5.9 Whittier Narrows earthquake in 1987, according to seismologist Dr. Lucy Jones.

There have been reports that the quake was felt in La Habra, Long Beach, Oxnard, Ontario, Pasadena, near the Beverly Hills area, and other regions throughout L.A. County.

Some residents said they felt jolts from about three seconds to possibly up to a minute long.

All 106 fire stations in the city of Los Angeles activated, each checking their areas for damage, according to Los Angeles Fire Chief Ralph M. Terrazas.

This is one of the largest earthquakes in the Los Angeles Basin in a few years.

Jones said that 5% of the time, an initial earthquake may actually be a foreshock that is preceding a larger earthquake.

There is also an approximately 50% chance that an aftershock around 3.0 magnitude strength could be felt, according to Jones.

There were no reports of extensive damages or injuries in the city of L.A. on Friday night, Chief Terrazas said.

The Los Angeles Police Department also said there were “no significant incidents to report” related to the earthquake, but urged residents to have plans in place should aftershocks occur.

Call 911 for emergencies or dial 877-275-5273 (877-ASK-LAPD) for non-emergencies in the City of Los Angeles.

    actually 60 freeway and santa anita will experience longer shaking than up on Potrero Heights
    Thats near seismic stations RUS and WNGC which frequently show the most ground motions anywhere in LA County that’s not directly on the San Andreas
    They are both about equal distant from the 10 mile deep hypocenter
    If no damage there all is good
    There was nothing open around the epicenter
    nice report Joy
    but El Monte-??? who wrote that?
