Why Some Quakes Shake Faster Revealed By Tabletop Fault Model
2012-10-31 15:28:04

University of California - Berkeley The more time it takes for an earthquake fault to heal, the faster the shake it will produce when it finally ruptures, according to a new study by engineers at the University of California, Berkeley, who conducted their work using a tabletop model of a quake fault. "The high frequency waves of an earthquake – the kind that produces the rapid jolts – are not well understood because they are more difficult to measure and more difficult to...

Changes in seismic velocity--changes in the speeds at which seismic waves move through the Earth's crust--have been identified during and after many earthquakes. But do these changes also happen before an earthquake, and could they be measured as a way to predict a quake on the way? The search for a clear and measurable pre-quake signal has been called "the holy grail of seismology." In a new analysis of the 2004 magnitude 6.0 Parkfield earthquake in California, David Schaff suggests some...

Deep Tectonic Tremors Provide Clues About Shallow Earthquakes

Brett Smith for redOrbit.com - Your Universe Online Although the earth is shaken by approximately 80,000 earthquakes every month, not many of them will send you running for the nearest doorway. However, scientists, led by a team at Karlsruhe Institute of Technology (KIT) in Germany, have recently started investing more time and research into understanding these subtle vibrations that occur deep in the Earth´s crust. More specifically, these researchers are interested in tectonic...

  Scientists hope findings bring them closer to earthquake forecasting "What do I remember about an earthquake? I was in the 7th grade. All of a sudden the floor just started shaking. Desks were falling over. Kids were falling on the ground. It was so scary. It happened so quickly!" For people like Tony Zurnick, part of growing up in California was getting caught off guard by the sudden rumbles of earthquakes. Anyone who has lived through a major earthquake will tell you they'd...

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...

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...

Using a technique normally used for detecting weak tremors, scientists at the Georgia Institute of Technology discovered that the 2004 magnitude 6 earthquake along the Parkfield section of the San Andreas fault exhibited almost 11 times more aftershocks than previously thought.  The research appears online in Nature Geoscience and will appear in print in a forthcoming edition. "We found almost 11 times more events in the first three days after the main event. That's surprising because...

With an average of four mini-earthquakes per day, Southern California's San Jacinto fault constantly adjusts to make it a less likely candidate for a major earthquake than its quiet neighbor to the east, the Southern San Andreas fault, according to an article in the journal Nature Geoscience. "Those minor to moderate events along the San Jacinto fault relieve some of the stress built by the constantly moving tectonic plates," said Shimon Wdowinski, research associate professor at the...

U.S. scientists studying the giant 2004 earthquake that caused Indian Ocean tsunamis say they've determined the quake weakened part of the San Andreas Fault. The seismologists said their findings suggest the Earth's largest earthquakes can weaken fault zones worldwide and might trigger periods of increased global seismic activity. An unusually high number of magnitude 8 earthquakes occurred worldwide in 2005 and 2006, said Rice University Associate Professor Fenglin Niu, one of the study's...

Tremors deep within the San Andreas Fault suggest California should not become complacent about future earthquakes, a leading seismologist said. The San Andreas fault is changing down deep and it's changing down deep in places where large earthquakes have happened in the past, said Robert Nadeau, a research seismologist at the University of California, Berkeley. Seismic activity in the central part of the fault has increased in the years since the magnitude 6.5 San Simeon quake in 2003 and...
