The Big One could trigger series of large earthquakes, study findsA new research released Wednesday suggests that the shaking from “the Big One,” the long-predicted major earthquake on the San Andreas fault, could trigger additional large temblors on nearby faults, intensifying the overall seismic impact. The study suggests that such a quake “could presage a flurry of ‘other Big Ones’ on other faults,” said USC earth sciences professor James Dolan, “as stresses related to the original San Andreas fault earthquake are redistributed on other faults throughout Southern California.” The study, being presented by Dolan on Wednesday at a meeting of the Seismological Society of America in Pasadena, focuses on whether earthquakes are generated in “super-cycles.” An earthquake “super-cycle” refers to when a large number of earthquakes rupture on a single fault system in a relatively short period of time, like over a matter of decades or a few centuries. The concept of more than one Big One in a lifetime might feel outlandish to Californians today. But it wasn’t so long ago when this state had more powerful earthquakes more frequently. The San Andreas fault, for example, suffered two major ruptures in the 19th century: an earthquake of about magnitude 7.5 in 1812 and a much worse 7.9 earthquake in 1857. FULL REPORT
