M3.3 Earthquake 14 km WSW of Manhattan Beach, CA — June 10, 2025
2025-06-10 19:15:47 UTC (2025-06-10) · approx. 11:15 AM UTC-8 local
Felt by 851 people across surrounding communities.
On June 10, 2025 at 19:15 UTC, a magnitude 3.3 shallow crustal earthquake struck 14 km WSW of Manhattan Beach, CA, at a depth of 10.4 km and coordinates 33.8272°, -118.5517°. The earthquake was reported felt by 851 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.2 (light). This earthquake was detected by 113 seismic stations with good location accuracy and was assigned a USGS significance rating of 469, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 105 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in California, a region characterized by the San Andreas transform fault system, where the Pacific and North American plates slide past each other at roughly 46 mm per year. The nearest mapped fault system is the San Andreas Fault. View all earthquakes in California.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.3 earthquakes can continue for several days and gradually diminish over time.
Has California had earthquakes this big before?
The largest recorded earthquake in California was the M7.9 Fort Tejon earthquake of January 9, 1857. Today's magnitude 3.3 event is significantly smaller than that historical record.
