The San Jose area averages about 7 magnitude 4.0+ earthquakes per year and has recorded 32 earthquakes (M1.0+) within 50 km in the past 30 days. The largest event in the past 30 days was a magnitude 3.0 event 5 km ESE of Interlaken, CA.

San Jose sits in the very high category for U.S. seismic activity. The largest earthquake in or near San Jose since records began was the magnitude 6.9 Loma Prieta earthquake in 1989, which struck approximately 25 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 San Jose in the next 30 years, and a 51% probability of a magnitude 7.0 or greater event. The largest credible earthquake predicted for the San Jose area is a magnitude 7.0 event on the Calaveras Fault, which lies 5 km from downtown San Jose.

San Jose 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 Calaveras Fault, secondary fault systems include the Hayward Fault and San Andreas Fault (Santa Cruz Mountains). View all earthquakes in California.

Dataset at a glance — San Jose

Over the past 30 days, San Jose has recorded 32 earthquakes of magnitude 2.5 or greater in our tracker. The remaining 1 fell in the M2.5–M3.9 band. By depth: 32 shallow (<70 km). 14 of the epicenters were offshore. 6 events produced at least one felt report, totalling 136 citizen submissions to the USGS Did You Feel It? system. Focal depths ranged from -0.2 km to 12.4 km. 18 of the 32 solutions have been reviewed by a USGS seismologist; the remaining 14 are automatic and may be refined.

Common Questions About Earthquakes in San Jose

How often do earthquakes happen in San Jose?

San Jose experiences frequent earthquake activity. The area averages 60 earthquakes of magnitude 3.0 or greater per year, with 0.8 reaching magnitude 5.0 or higher. In the past 30 days, 32 earthquakes (M1.0+) have been recorded within 50 km of the city.

What was the biggest earthquake to hit San Jose?

The largest earthquake in or near San Jose since records began was the magnitude 6.9 Loma Prieta earthquake in 1989, which struck approximately 25 km south of the city.

What is the earthquake risk in San Jose?

Earthquakes cannot be predicted with precision. However, the U.S. Geological Survey estimates there is approximately a 72% probability of a magnitude 6.7 or greater earthquake within 100 km of San Jose in the next 30 years. The most likely source is the Calaveras Fault, which has a maximum credible magnitude of 7.0.
