The city sits along the Calaveras Fault, and several micro-faults along the main fault result in swarms of quakes. When fluids like water or gas move through a complex web of cracks in tiny faults, this can trigger many dozens of small quakes in quick succession.
On Feb. 27, the city of San Ramon hosted a Q&A with local mayors, Supervisor Candace Andersen, SRVFPD Chief Jonas Aguiar, and UC Berkeley seismologist Dr. Angie Lux.
