 The members conduct a teleconference within several hours of a major temblor.From 1986 through 2016, CEPEC convened a total of 17 times to evaluate recent or ongoing seismic activity.For example, following the 2016 earthquake swarm at Bombay Beach, CEPEC released a statement to CalOES estimating that the probability of a magnitude 7 or larger earthquake on the San Andreas fault for the following week was between 0.03% and 1%.
