Why San Ramon has been in the spotlight for quakes lately
The San Ramon area has drawn attention in recent weeks due to a notable earthquake “swarm” in the Tri-Valley/East Bay region, with dozens of small quakes recorded over late 2025. Experts have said swarms can happen without signaling that a major quake is imminent, but they serve as an important reminder to stay prepared. San Francisco Chronicle+2Los Angeles Times+2
