Los Angeles experienced a magnitude 3.3 earthquake 3 days ago 26 km ESE of Avalon, CA, at a depth of 10.7 km. Over the past 7 days, 137 earthquakes (M1.0+) have been recorded within 100 km.
Los Angeles sits in the very high category for U.S. seismic activity. The largest earthquake in or near Los Angeles since records began was the magnitude 7.5 Kern County earthquake in 1952, which struck approximately 130 km north of the city.
According to the U.S. Geological Survey's UCERF3 model, there is approximately a 60% probability of a magnitude 6.7 or greater earthquake within 100 km of Los Angeles in the next 30 years, and a 46% probability of a magnitude 7.0 or greater event. The largest credible earthquake predicted for the Los Angeles area is a magnitude 7.4 event on the Newport-Inglewood Fault, which lies 8 km from downtown Los Angeles.

Los Angeles sits in 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. Beyond the Newport-Inglewood Fault, secondary fault systems include the Puente Hills Thrust Fault and Hollywood Fault. View all earthquakes in California.
