In California's East Bay, a recent swarm of small earthquakes has pushed long-standing seismic risks back into public view. Since early November 2025, at least 90 minor quakes have been recorded around San Ramon,

A swarm of at least six earthquakes reaching up to magnitude 2.9 rattled San Ramon near San Francisco, the U.S. Geological Survey reports. The other quakes in the Saturday, Dec. 13, swarm ranged from magnitude 1.3 to 2.3, according to the USGS.

California's seismic risk is increasing with supershear earthquakes, which are faster and more destructive than typical earthquakes.

Major quakes in Japan and Alaska along with a spate of smaller earthquakes in California this fall make folks ask, is the Big One near?

Residents in Nevada woke up to a shocking 5.9 magnitude earthquake alert, but after the panic settled, the whole thing turned out to be a fake quake alert sent by USGS.

The ShakeAlert system that warns about imminent shaking arriving from earthquakes sent a false alarm across California on Thursday morning for a magnitude 5.9 temblor that did not happen.

On Monday morning, around 30 minor earthquakes erupted in a swarm near the Geysers geothermal field south of Clear Lake. The day before, seven quakes rattled Sonoma County, including a 4.0 quake. The recent uptick isn’t out of the ordinary, according to U.S. Geological Survey seismologist Susan Hough.
