Monday Morning Quake Hits East Bay A 2.8-magnitude earthquake struck San Ramon early Monday morning, according to the U.S. Geological Survey. The tremor occurred at 3:34 a.m., just north of Bollinger Canyon Road and east of Alcosta Boulevard, near the Bridges Golf Club. The quake had a depth of 8.9 kilometers, with nearby residents reporting weak to light shaking. This event marks the latest in a series of seismic activities affecting the area since November. San Ramon has experienced multiple quakes, including another 2.8-magnitude tremor on Friday, March 13. The city’s location along the Calaveras Fault contributes to frequent seismic activity, as micro-faults within the main fault line can trigger swarms of small quakes. Fluid movement through cracks in these faults often leads to rapid sequences of minor tremors. The city has also hosted discussions on earthquake preparedness. On February 27, San Ramon organized a Q&A session featuring local mayors, Supervisor Candace Andersen, SRVFPD Chief Jonas Aguiar, and UC Berkeley seismologist Dr. Angie Lux. The event addressed concerns about the region’s seismic activity and strategies for community readiness. While the recent quake did not cause significant damage, it underscores the ongoing challenges posed by the area’s geological conditions. Residents and officials continue to monitor seismic trends, with efforts focused on enhancing resilience and public awareness.#san_ramon #calaveras_fault #bridges_golf_club #candace_andersen #jonas_aguiar
