    For decades, scientists have assumed the central portion of California’s San Andreas fault acts as a barrier that prevents a big quake in the southern part of the state from spreading to the north, and vice versa. As a result, a mega-quake that could be felt from San Diego to San Francisco was widely considered impossible. But that key fault segment might not serve as a barrier in all cases, researchers wrote Wednesday in the online edition of the journal Nature. Using a combination of laboratory measurements and computer simulations, the two scientists showed how so-called creeping segments in a...

    Earthquakes the size of the one that struck Japan on Friday are highly unlikely ever to hit the California coast, but smaller quakes along the San Andreas or Hayward faults could prove just as devastating, experts say. No temblor greater than a magnitude 8 is ever likely in California, say scientists at the U.S. Geological Survey in Menlo Park. "But the next big quake in the Bay Area on either the San Andreas or the Hayward will be a $200 billion disaster," warned Thomas M. Brocher, who leads the USGS region's efforts at preparedness for the next Big One. The...

    The 340-mile, southern section of the San Andreas fault could slip at anytime, triggering a massive, magnitude 8.1 quake, researchers announced Sunday. A report in the August issue of Geology by researchers at UC Irvine and Arizona State University suggest the fault is long overdue for a major quake — running from Monterey County to the Salton Sea, the Los Angeles Times reported. The last major rupture on the San Andreas was in 1857. Until recently, experts believed that the section of the fault through the Carrizo Plain, located approximately 100 miles northwest of Los Angeles, would remain dormant for...

    California - land of sun, beaches and earthquakes - faces an almost certain risk of being rocked by a strong temblor by 2037, scientists said Monday in the first statewide forecast of the seismic threat. New calculations reveal there is a 99.7 percent chance a magnitude 6.7 quake or larger will hit the Golden State in the next 30 years. The odds of such an event are higher in Southern California than Northern California, 97 percent versus 93 percent. The last time a jolt this size rattled California was the 1994 Northridge disaster, which killed 72 people, injured more than...

    New earthquake research confirms the southern end of the San Andreas fault near Los Angeles is overdue for a Big One. The lower section of the fault has not produced a major earthquake in more than three centuries. ADVERTISEMENT The new study, which analyzed 20 years of data and is considered one of the most detailed analyses yet, found that stress has been building up since then, and that the fault could rupture at any moment. "The southern section of the fault is fully loaded for the next big event," said geophysicist Yuri Fialko of the Scripps Institution of Oceanography...

    July 27, 2006 La Jolla, California - Last month, the June 22, 2006, issue of the science journal Nature, published recent detailed research of the San Andreas and San Jacinto faults in Southern California. The data shows the San Andreas so stressed that its next quake release of energy could be a magnitude 8 on the Richter scale. The San Andreas Fault is considered the main boundary between the Pacific and North American tectonic plates that are slowly moving past each other. Some day in the far distant future, those moving plates might even break off sections of the Pacific...

    Overview To better understand the distribution of shaking and damage that accompanied the great 1906 earthquake, seismologists have constructed new computer models to recreate the ground motions. The simulations show how ground moved on the two sides of the San Andreas fault and how seismic waves radiated away from the fault to produce the shaking. The earthquake, which began 2 miles offshore from the City of San Francisco, ultimately grew to cause shaking and damage along more than 300 miles of the San Andreas Fault. The movies and snapshots available here portray the shaking over a 155 mile by 70...

    In Las Vegas, folks can't wait for the "Big One," the massive earthquake that will some day cause California to fall into the ocean. When it happens, the joke goes, Las Vegas becomes waterfront property. It's not true, of course. When the "Big One" does strike, today or a thousand years from now, California isn't likely to fall anywhere except down. Still, don't bet entirely against that notion of new waterfront property. A monster earthquake won't create it, but scientists say the passage of time and giant crustal plates might. Someday, Southern Californians might enjoy ocean views not just to...

    Mysterious tremors deep beneath the San Andreas Fault near the quake-prone town of Parkfield are shaking the earth's brittle crust, far below the region where earthquakes normally strike -- and scientists say they can't understand what's happening or what the motions mean. Seismic researchers are monitoring the strange vibrations closely. But whether the faint underground tremors -- termed "chatter" by some seismologists -- portend an increased likelihood of a major quake in the area is an unsolved puzzle. Robert Nadeau, a geophysicist at the UC Berkeley Seismological Laboratory, charted more than 110 of the faint vibrations since they were first...

    LOS ANGELES (AP) - A new study concludes that a long stretch of the mighty San Andreas Fault close to highly populated Southern California has usually only had very large earthquakes. The researchers' finding challenge an idea that frequent small temblors slowly relieve accumulating strain on faults and therefore reduce the likelihood of big quakes. Digging trenches at a site on the San Andreas 120 miles northwest of Los Angeles, geologists identified six events and found evidence that about 95 percent of slippage there has occurred during big quakes, with magnitudes ranging from 7.5 to 8, according to the study...
