LOS ANGELES >>  Seismologists say a mild earthquake widely felt throughout Southern California was centered along the coast west of downtown Los Angeles.

No injuries were reported.

The U.S. Geological Survey says the magnitude-3.7 quake struck at 3:18 a.m. Wednesday. The quake initially was reported as a magnitude-3.8, but seismologist Kate Hutton says it was later found to be a 3.74 so it was downgraded.

The epicenter was 2 miles east-southeast of Marina del Rey near Culver City and Inglewood. A Sheriff’s Department dispatcher says it “wasn’t much of a quake” and no one called about it.

Dozens of people from as far away as Riverside and the San Fernando Valley logged onto the USGS website to report feeling the jolt.

Fire Department spokesman Matt Spence says firefighters rolled out of stations citywide and surveyed 470 square miles. No infrastructure or other damage was found.
