San Jose, CA – A small earthquake rattled parts of the South Bay early Thursday morning, with residents near San Jose reporting brief shaking.
According to the U.S. Geological Survey (USGS) and the California Integrated Seismic Network (CISN), a magnitude 3.1 earthquake struck 24 kilometers east-northeast of Alum Rock, near San Jose, at approximately 6:54 a.m. local time on Wednesday. The quake occurred at a depth of about 8.8 kilometers, classifying it as a shallow earthquake.
The epicenter was located in Santa Clara County, within the greater San Jose–Silicon Valley region of Northern California. Community responses submitted to the USGS “Did You Feel It?” program indicated light shaking, with no immediate reports of damage or injuries.
Seismologists note that earthquakes in the magnitude 3 range are common in the Bay Area and are often felt by people nearby but rarely cause structural damage. The region sits atop several active fault systems, including the Hayward and Calaveras faults, making minor seismic activity a regular occurrence.
Emergency officials have not issued any alerts, and no service disruptions were reported as of Wednesday morning. Residents are encouraged to review earthquake safety plans and ensure emergency kits are up to date, especially as smaller quakes can occasionally precede larger events.
Anyone who felt the shaking is encouraged to submit a report through the USGS website to help scientists better understand how the quake was experienced across the region.
