    A small earthquake shook a widespread part of the Los Angeles area Thursday morning, the US Geological Survey reported.

    Weak shaking was reported in Carson, LA, the South Bay, Pomona, Orange County and other nearby communities from the 7:01 a.m. tremor, measured as a 3.4 magnitude earthquake, the USGS said.

    The USGS initially reported the quake as a magnitude 3.6, briefly upgraded it to a 3.7, then later downgraded the activity to a 3.4. It struck at a depth of about 7.5 miles, two miles from Carson.

    "I was dead asleep and felt a big jolt. It woke me right up," Carson resident Lori Vidal said.

    The Los Angeles County Fire Department and Sheriff's Department had not received any reports of damage by 7:14 a.m. The earthquake caused short delays on Metro Los Angeles trains, the agency tweeted, but full service was restored before 7:30 p.m. after a systemwide inspection turned up no damage.

    The quake was near the Newport-Inglewood Fault Zone, which includes the communities of Culver City, Inglewood, Compton, Long Beach, Huntington Beach, Newport Beach and Costa Mesa. The fault also extends southeast into the ocean.

    In 1933, the magnitude-6.4 Long Beach Earthquake that resulted in 120 deaths and more than $50 million in property damage was in the fault zone, according to the Southern California Earthquake Data Center. Most of the damage was to unreinforced masonry buildings.
