Magnitude 3.4 earthquake rattles coastal Los Angeles County, no damage reported

A mild earthquake measuring 3.4 on the Richter scale struck off the coast of Manhattan Beach on Tuesday, June 10, 2025, sending gentle tremors across parts of Los Angeles County but causing no reported damage or injuries. The U.S. Geological Survey (USGS) pinpointed the quake’s epicenter about nine miles west of Manhattan Beach, at a depth of approximately seven miles beneath the Pacific Ocean.

The seismic event occurred at 12:15 p.m. local time and was felt across a broad swath of the L.A. basin, from the South Bay to West Los Angeles. While the shaking was noticeable to residents, especially in coastal neighborhoods, emergency services including the Los Angeles Fire Department confirmed that they received no calls for help and no incidents of structural damage were reported.

Earthquakes of this magnitude are considered minor and are relatively common in Southern California, a region crisscrossed by numerous fault lines. According to USGS data, the greater Los Angeles area experiences an average of 59 earthquakes with magnitudes between 2.0 and 3.0 each year. Tuesday’s quake, however, was slightly stronger and served as a reminder of the region’s seismic activity.


Social media lit up as Angelenos shared their experiences, with many describing a brief but perceptible jolt. “It felt like a quick shake, nothing too scary but definitely noticeable,” said one Manhattan Beach resident on Instagram.

Seismologists advise that while quakes of this size rarely cause damage, they are a good prompt for residents to review their earthquake preparedness plans. As always, officials encourage Southern Californians to stay informed and ready for larger events, given the state’s long history with significant seismic activity.
