New dynamic computer model first to show full history of a fault segment For those who study earthquakes, one major challenge has been trying to understand all the physics of a fault–both during an earthquake and at times of "rest"–in order to know more about how a particular region may behave in the future. Now, researchers at the California Institute of Technology (Caltech) have developed the first computer model of an earthquake-producing fault segment that reproduces, in a...

   Less than a day after Virginia was hit with a 5.8 magnitude Earthquake, Peru felt the force of a 7.0 magnitude quake. The U.S. Geological Survey said the quake's epicenter was about 350 miles northeast of the capital Lima, 51 miles north of the town of Puccalpa. It said that there were no immediate reports of damage or casualties and no tsunami was expected to occur as a result. The agency said the quake occurred 90 miles underground at about 12:46 p.m. local...

In a US study, researchers said that strong earthquakes recorded along the San Andreas fault in southern California are more frequent than previously believed, and they fear the "Big One" could be just around the corner.Scientists at the University of California at Irvine and Arizona State University examined geological records stretching back 700 years along the fault line about 100 miles northwest of Los Angeles.They found that strong earthquakes -- 6.5 to 7.9 magnitude -- occurred every 45...

SACRAMENTO, Calif., March 5 /PRNewswire/ -- A majority of Californians have taken initial steps toward earthquake preparedness but more than 60 percent of Californians have not done enough to make their homes safer and guard their personal finances in preparation for an inevitable, large-scale earthquake, according to a recent California Earthquake Preparedness Survey. Although state and local public safety and emergency management agencies are better prepared than ever before,...

A preliminary U.S. Geological Survey assessment has found that the sequence of aftershocks following the magnitude 7 earthquake that struck near Port-au-Prince, Haiti on Jan. 12 is likely to continue for months, possibly years. The capital was hit by two fresh aftershocks on Friday, 10 days after the initial 7.0-magnitude quake killed at least 75,000 people and left half a million others homeless. A team of USGS scientists predict that for the next 30 days there is a 3 percent chance of a...

Stream channel offsets features linked to large earthquakes Recent studies of stream channel offsets along the San Andreas Fault reveal new information about fault behavior--changing our understanding of the potential for damaging earthquakes. The studies were conducted at the Carrizo Plain, 100 miles north of Los Angeles and site of the original "Big One"--the Fort Tejon quake of 1857--by scientists at Arizona State University (ASU) and the University of California at Irvine (UCI).Applying a...

SAN FRANCISCO, Oct. 9 /PRNewswire/ -- With the 20th anniversary of the 1989 Loma Prieta Northern California Earthquake happening this month, earthquake engineers and authors Peter Yanev and Andrew Thompson have completely updated and expanded the best-selling 1974 book Peace of Mind in Earthquake Country: How To Save Your Home, Business, and Life. This all new edition--available in bookstores now--features new information and photos, and distills the essentials everyone needs to know...

A spike in mysterious underground rumblings observed on a section of the San Andreas fault near Parkfield, California, could indicate a build-up of stress and an increased likelihood of a major earthquake, said scientists at the University of California, Berkeley. The researchers monitored seismic activity along a heavily instrumented segment of the central San Andreas Fault from July 2001 to February 2009, and recorded more than 2,000 tremors lasting from minutes to nearly half an hour....

Southern California could be overdue for a major earthquake along the San Andreas Fault, researchers say. A study by scientists at the University of California at Irvine found there were five major temblors along a southern section of the San Andreas Fault in the past 700 years, the Los Angeles Times reported Saturday. The first one is estimated to have occurred in 1310, followed 83 years later by one in 1393, 192 years after that in 1585, the next 85 years later in 1640 and the last one 217...

A strong, magnitude 6.1 earthquake struck the British Virgin Islands Saturday, the U.S. Geological Survey said. No immediate information was available about possible damage from the 6:40 a.m. quake, centered about 51 miles northwest of The Settlement on Anegad, a sparsely populated northern atoll of the British Virgin Islands, the quake-monitoring agency said. The USGS placed the depth of the quake at 16 miles.
