A preliminary 4.0‑magnitude earthquake struck near Gilroy early Wednesday, November 26, shaking parts of the San Francisco Bay Area. The U.S. Geological Survey (USGS) reported that the quake occurred around dawn and was followed by several smaller aftershocks.
Residents from San Jose to Morgan Hill shared accounts of light to moderate shaking. While no major damage or injuries were reported, the tremors reminded locals of the region’s active seismic history along the Calaveras and San Andreas faults.
According to the USGS, the epicenter was located just east of Gilroy, a city about 30 miles southeast of San Jose. The depth of the quake was measured at roughly 6 miles (10 kilometers). Several minor aftershocks in the range of 2.5 to 3.1 magnitude followed within an hour.
Emergency services confirmed that there were no interruptions to utilities or transportation, though authorities urged residents to check emergency kits and review safety procedures.
“Even small quakes are reminders that preparedness matters,” said a spokesperson for the California Governor’s Office of Emergency Services.
Many Bay Area residents reported the shaking to the USGS’s “Did You Feel It?” system, which tracks community responses during earthquakes. Social media filled with posts describing brief but noticeable tremors lasting only a few seconds.
Local officials stated that earthquake activity in this area is common and typically results from stress along the major regional fault lines.
A shallow 4.0‑magnitude quake near Gilroy briefly shook the Bay Area, causing no damage but serving as a strong reminder of California’s ongoing seismic activity.
