On November 9, 2025 at 17:38 UTC, a magnitude 3.8 earthquake struck 3 km SE of San Ramon, CA. In the 72 hours after this event, the USGS recorded 47 smaller earthquakes within 20 km, consistent with an ongoing aftershock sequence rooted here. Of every earthquake currently listed for worldwide seismic activity, this one generated the most felt reports from the public. The USGS received 596 felt reports from nearby residents — a notable response for an event of this magnitude. Maximum shaking intensity peaked at MMI 4.4 (moderate). The event originated approximately 9.2 km below the surface, classifying it as shallow crustal. The event was offshore — common for earthquakes along subduction zones and transform plate boundaries. The epicenter is at 37.758°, -121.953°. The solution has been reviewed by a USGS seismologist and is considered finalized. See the M3.8 event page for the full report, ShakeMap, and citizen-reported intensity data. | ||||||||
