Study: The Big One could trigger series of large quakes

Research released Wednesday suggests 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, presented by Dolan at a meeting of the Seismological Society of America in Pasadena, focuses on whether earthquakes are generated in “super cycles.” A super cycle refers to when a large number of quakes rupture on a single fault system in a relatively short period of time in seismic terms, over a matter of decades or a few centuries.
If the “big one” hits, let’s hope the Diablo Canyon Nuclear plant fairs better then Fukushima.
If the “big one” hits I hope we survive the Tahoe Tsunami. Get your canoe, kayaks and paddle boards ready to ride it out.
See you on top of Monument Peak. I’ll be the guy in the 17 ft. Grumman canoe with the BIG Great Pyreneese dog. Surfs up! OLS
OLS – My friend Carol has 2 of those big Great Pyreneese dogs – any room in the canoe? Beautiful dogs – I used to dog-sit for Luther – the big GP she had before the 2 current ones. Post a picture – they are sooo beautiful! and gentle.
