On Tuesday, June 10, 2025, at 12:15 p.m. PDT, a 3.3 magnitude earthquake struck off the coast of Los Angeles County, with its epicenter located approximately nine miles southwest of Manhattan Beach and Hermosa Beach at a depth of about 6.4 miles.
The U.S. Geological Survey (USGS) reported the event, noting that the quake was initially estimated at a magnitude of 3.4 by some sources before being revised.
Despite its modest strength, the shaking was felt across a wide area, including Manhattan Beach, Riverside, and as far south as Oceanside, nearly two hours from the epicenter.
Social media reports described the earthquake as “really fast, but sharp,” with residents from Santa Monica, Venice, Inglewood, Redondo Beach, Torrance, and downtown Los Angeles noting the tremors.
No damage or injuries were reported, and officials confirmed there was no tsunami threat. The Los Angeles Fire Department conducted surveys across its 106 fire stations to check for structural damage, finding none.
This event adds to Southern California’s active seismic year, with at least nine significant earthquakes recorded in 2025, including a 5.2 magnitude quake near Julian on April 14 and a 4.1 magnitude quake near Malibu on March 10.
The region’s history of seismic activity keeps residents vigilant, though experts emphasize that these smaller quakes do not necessarily signal an imminent larger event.
The earthquake occurred near the Palos Verdes Peninsula in the North Pacific Ocean, close to the Santa Monica Bay. While some social media posts speculated about proximity to the Malibu Fault, the USGS did not confirm a specific fault for this event.
Southern California sits on multiple fault lines, including the Elsinore and Newport-Inglewood faults, with the latter responsible for the devastating 1933 Long Beach earthquake.
Seismologist Susan Hough from the USGS noted that while the Elsinore fault moves at about 5 millimeters per year, it is less likely to rupture compared to the faster-moving San Andreas fault.
