Study of 2004 tsunami forces rethinking of giant earthquake theory
The Sumatra-Andaman earthquake of Dec. 26, 2004, was one of the worst natural disasters in history, largely because of the devastating tsunami that followed.   view more (2006-03-06)

Supercomputer Unleashes Virtual 9.0 Megaquake in Pacific Northwest
On January 26, 1700, at about 9 p.m. local time, the Juan de Fuca plate beneath the ocean in the Pacific Northwest suddenly moved, slipping some 60 feet eastward beneath the North American plate in a monster quake of approximately magnitude 9, setting in motion large tsunamis that struck the coast... view more (2008-02-27)

A sea change for earthquakes
A reconstruction of land movements and changes in sea levels for three massive historic earthquakes in Alaska gives clues that may help scientists forecast future earthquakes and earthquake-triggered tsunami. To be published in this week's Journal of Quaternary Science¹ the findings should help... view more (2005-02-21)

Forecasting the Next Great San Francisco Earthquake
The San Francisco Bay region has a 25 percent chance of a magnitude 7 or greater earthquake in the next 20 years, and a roughly 1 percent chance of such an earthquake each year, according to the "Virtual California" computer simulation.   view more (2005-10-14)

The area of influence of earthquakes could be larger than is currently thought
Dr Ãlvaro Corral, a Ramón y Cajal researcher for the UAB Department of Physics, studies the relationships between the time and place of earthquake occurrences (ie, the jumps between an initial earthquake and another earthquake at a later time in another place) using statistical physics methods.   view more (2006-11-22)

A crystal ball of earthquakes
When the next big earthquake hits a region like San Francisco, Natural Sciences and Engineering Research Council (NSERC) grantee Kristy Tiampo wants to ensure that communities will not only be able to evacuate, but also rebuild.   view more (2007-02-15)

Loma Prieta Fault Not So Weak?
A new study adds to evidence that the fault responsible for the 1989 Loma Prieta earthquake is not as unusually weak as had been thought.   view more (2007-12-20)

Geologists study China earthquake for glimpse into future
The May 12 earthquake that rocked Sichuan Province in China was the first there in recorded history and unexpected in its magnitude. Now a team of geoscientists is looking at the potential for future earthquakes due to earthquake-induced changes in stress.   view more (2008-07-07)

Durham scientist explores Sichuan fault
Durham University expert, Alex Densmore, is to explore the fault lines that caused the May 12th earthquake in China that killed 69,000 people.    view more (2008-08-14)

Expert challenges earthquake theory behind Indonesian mud volcano
A leading expert today repeated his assertion that an Indonesian mud volcano was almost certainly manmade despite a new study claiming the eruption might have been triggered by an earthquake.   view more (2007-08-01)

Stress Buildup Precedes Large Sumatra Quakes
The island of Sumatra, Indonesia, has shaken many times with powerful earthquakes since the one that wrought the infamous 2004 Indian Ocean tsunami. Now, scientists from the California Institute of Technology and the Indonesian Institute of Sciences are harnessing information from these and earlier... view more (2008-05-28)

Media bias distorts details of past earthquakes
The story of some violent historic earthquakes may need to be revisited, according to a study published in the April issue of the Bulletin of the Seismological Society of America (BSSA).   view more (2007-04-04)

Tonga quake not conducive to tsunami
Seismologists at Washington University in St. Louis and their colleagues in Australia, Japan and Tonga have determined why a large earthquake in Tonga did not cause a large tsunami.   view more (2007-03-13)

'Ultrasound' of Earth's crust reveals inner workings of a tsunami factory
Research announced this week by a team of U.S. and Japanese geoscientists may help explain why part of the seafloor near the southwest coast of Japan is particularly good at generating devastating tsunamis, such as the 1944 Tonankai event, which killed at least 1,200 people. The findings will help... view more (2007-11-16)

New method provides better earthquake warnings
The new method of analysis makes it possible to estimate the complete stress tensor and monitor changes in the magnitude of stress and the instability of faults, which roots the analysis in physics in a manner that earthquake methods normally lack.   view more (2007-01-15)

Earthquake swarms not just clustered around volcanoes, geothermal regions
An earthquake swarm - a steady drumbeat of moderate, related seismic events - over hours or days, often can be observed near a volcano such as Mount St. Helens in Washington state or in a geothermal region such as Yellowstone National Park in Wyoming.   view more (2006-10-26)

2006 tectonic plate motion reversal near Acapulco puzzles earthquake scientists
A reversal of tectonic plate motion between Acapulco and Mexico City in the last half of 2006 probably didn't ease seismic strain in the region or the specter of a major earthquake anticipated there in the coming decades, says a University of Colorado at Boulder professor.   view more (2007-08-03)

Why do earthquakes stop?
The underlying structure of a fault determines whether an earthquake rupture will jump from one fault to another, magnifying its size and potential devastation.   view more (2008-02-06)

Earthquake 'memory' could spur aftershocks
Using a novel device that simulates earthquakes in a laboratory setting, a Los Alamos researcher and his colleagues have shown that seismic waves-the sounds radiated from earthquakes-can induce earthquake aftershocks, often long after a quake has subsided.   view more (2008-01-04)

Chinese earthquake provides lessons for future
The May 12 Sichuan earthquake in China was unexpectedly large. Analysis of the area, however, now shows that topographic characteristics of the highly mountainous area identified the mountain range as active and could have pointed to the earthquake hazard. Topographic analysis can help evaluate... view more (2008-07-22)

Fewer Deaths than 2004, but Earthquakes Still Kill Nearly 90,000 in 2005
Although there were fewer deaths worldwide in 2005 due to earthquakes, more than 89,353 casualties were reported, according to the U.S. Geological Survey (USGS) and confirmed by the United Nations Office for Coordination of Humanitarian Affairs (OCHA).   view more (2006-01-16)

A Universal Law May Govern Time Elapsed Between Earthquakes
Surprisingly, the probability that an earthquake should reoccur in any part of the world is smaller, the longer the time since the last quake took place. This is one of the conclusions reached by the physicist 'lvaro Corral, researcher at the Universitat Autònoma de Barcelona (UAB). Corral... view more (2004-03-02)

UU Scientists Issue Indonesia Earthquake Warning
The stresses in the earth's crust which have resulted from the Sumatra-Andaman earthquake have significantly increased the risk of another large earthquake in the already-devastated Indonesian island of Sumatra, according to new research findings by scientists from the University of Ulster's School... view more (2005-03-16)

NASA data show earthquakes may quickly boost regional volcanoes
Scientists using NASA satellite data have found strong evidence that a major earthquake can lead to a nearly immediate increase in regional volcanic activity.   view more (2007-04-11)

Discovery sheds new light on cause of earthquakes
Research at the University of Liverpool into a large fault zone in the Atacama Desert in northern Chile has produced new insight into how fluid pressure can cause earthquakes.   view more (2006-12-14)
