13-year Cascadia Study Suggests Risk For Large Earthquake
2012-08-01 13:16:27

A comprehensive analysis of the Cascadia Subduction Zone off the Pacific Northwest coast confirms that the region has had numerous earthquakes over the past 10,000 years, and suggests that the southern Oregon coast may be most vulnerable based on recurrence frequency. Written by researchers at Oregon State University, and published online by the U.S. Geological Survey, the study concludes that there is a 40 percent chance of a major earthquake in the Coos Bay, Ore., region during the next...

New Evidence For Regular Magnitude 8 Earthquakes On Alpin Fault
2012-07-27 13:21:39

redOrbit Staff & Wire Reports - Your Universe Online The most dangerous fault line on the island of New Zealand is the Alpine Fault. It is approximately 80 miles northwest of the islands main city of Christchurch. Research published in the prestigious journal Science, co-authored by University of Nevada, Reno's Glenn Biasi and colleagues at GNS Science in New Zealand, shows that very large earthquakes have been occurring regularly on the Alpine Fault along the southwest coastline of...

Caltech researchers provide highest-resolution observations yet of the complex 2012 Sumatra earthquake The powerful magnitude-8.6 earthquake that shook Sumatra on April 11, 2012, was a seismic standout for many reasons, not the least of which is that it was larger than scientists thought an earthquake of its type could ever be. Now, researchers from the California Institute of Technology (Caltech) report on their findings from the first high-resolution observations of the underwater...

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...

Caltech Researchers Gain Greater Insight Into Earthquake Cycles

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...

Scientists Gather To Discuss Possibility Of San Diego Quakes
2012-04-13 06:55:48

Things could get shaky as scientists will gather in San Diego next week to present their latest seismological research at the annual conference of the Seismological Society of America (SSA). This year´s conference is expected to have record numbers, as well as a special public town hall meeting which will feature talks on the seismic dangers in San Diego as well as the threat of future earthquakes and tsunamis. As the city of San Diego sits on top of a fault system, there is a...

BSSA is published by the Seismological Society of America. 2010 Haiti quake possible start of new cycle of seismic activity, according to new study. The January 2010 quake that destroyed much of Port-au-Prince may have marked the start of a new cycle of active seismicity, putting Haiti and the Dominican Republic at high risk of future devastating earthquakes. The island of...

  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...

Like scars that remain on the skin long after a wound has healed, earthquake fault lines can be traced on Earth's surface long after their initial rupture. Typically, this line of intersection between the area where the fault slips and the ground is more complicated at the surface than at depth. But a new study of the April 4, 2010, El Mayor"“Cucapah earthquake in Mexico reveals a reversal of this trend. While the fault involved in the event appeared to be superficially straight, the...

MIT researchers report that they have reconstructed Baja California's 2010 "Easter Earthquakes." The earthquake that shook Baja California took placed on April 4, 2010, sending tremors throughout a region 40 miles south of the U.S. - Mexico border. The months after the 7.2-magnitude earthquake triggered aftershocks that shook Los Angeles. "The southern San Andreas Fault has not had a major earthquake on it since the 1600s," Thomas Herring, professor of geophysics in the Department of Earth,...
