Oakland experienced a magnitude 3.8 earthquake 5 days ago 3 km N of San Leandro, CA, at a depth of 5.5 km. Over the past 7 days, 23 earthquakes (M1.0+) have been recorded within 50 km.

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. Source: UCERF3 (Field et al. 2015), Table 6 — Hayward Fault Zone (32% individual fault probability)

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.

Dataset at a glance — Oakland

Over the past 30 days, Oakland has recorded 53 earthquakes of magnitude 2.5 or greater in our tracker. The remaining 4 fell in the M2.5–M3.9 band. By depth: 53 shallow (<70 km). 28 of the epicenters were offshore. 10 events produced at least one felt report, totalling 8,405 citizen submissions to the USGS Did You Feel It? system. Focal depths ranged from -0.2 km to 16.1 km. 26 of the 53 solutions have been reviewed by a USGS seismologist; the remaining 27 are automatic and may be refined.
