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 reduce losses from future catastrophic events. 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)
Monitoring Yellowstone earthquake swarms
The Seismological Society of America (SSA) is an international scientific society devoted to the advancement of seismology and its applications in understanding and mitigating earthquake hazards and in imaging the structure of the earth. view more (2009-04-10)
New NIST publication series addresses design of earthquake-resistant structures
Where can you find some of the latest insights in designing earthquake-resistant buildings joined together with current information on building codes? view more (2008-09-05)
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)
How do they spread?
Propagation of earthquake waves within the Earth is not uniform. Experiments indicate that the velocity of shear waves (s-waves) in Earth's lower mantle between 660 and 2900 km depth is strongly dependent on the orientation of ferropericlase. view more (2009-04-13)
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)
Understanding risk to Seattle's high-rise buildings from a giant Cascadian earthquake
The Cascadia subduction zone is likely to produce the strongest shaking experienced in the lower 48 states. Although seismic activity in the Pacific Northwest has been relatively low in the past two centuries, there is a growing consensus that this fault zone ruptures in giant earthquakes (magnitude exceeding 9); the last rupture is inferred to... view more...

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)
Great Indian Ocean earthquake of 2004 set off tremors in San Andreas fault
In the last few years there has been a growing number of documented cases in which large earthquakes set off unfelt tremors in earthquake faults hundreds, sometimes even thousands, of miles away. view more (2008-12-11)
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)
Magmatically triggered slow earthquake discovered at Kilauea Volcano, Hawaii
Kilauea experienced a new dike intrusion, where magma rapidly moved from a storage reservoir beneath the summit into the east rift zone and extended the rift zone by as much as 1 meter. view more (2008-08-29)
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)
