The Oakland area averages about 8 magnitude 4.0+ earthquakes per year and has recorded 49 earthquakes (M1.0+) within 50 km in the past 30 days. The largest event in the past 30 days was a magnitude 2.4 event 2 km NNE of Hayward, CA.
Oakland sits in the very high category for U.S. seismic activity. The largest earthquake in or near Oakland since records began was the magnitude 6.9 Loma Prieta earthquake in 1989, which struck approximately 80 km south of the city.
According to the U.S. Geological Survey's UCERF3 model, there is approximately a 72% probability of a magnitude 6.7 or greater earthquake within 100 km of Oakland in the next 30 years, and a 51% probability of a magnitude 7.0 or greater event. The largest credible earthquake predicted for the Oakland area is a magnitude 7.0 event on the Hayward Fault, which lies 0.5 km from downtown Oakland.

Oakland 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 Hayward Fault, secondary fault systems include the Calaveras Fault and San Andreas Fault (Peninsula). View all earthquakes in California.
