Bombay Beach Highlights Difficulties in Earthquake Forecasting
18 April 2017-DENVER — In September 2016, about 100 small earthquakes between magnitude 2 and 4.3 took place in Bombay Beach, rattling the region in Southern California and raising questions about whether the swarm’s location near the southern end of the San Andreas Fault would trigger a larger earthquake.
In a presentation at the 2017 SSA Annual Meeting, U.S. Geological Survey seismologist Andrea Llenos discussed lessons learned from the 2016 Bombay Beach swarm, in particular the challenges in modeling swarms and communicating their risk to the public.
