New activity on old fault lines: French earthquake no surprise
The relatively powerful earthquake that hit eastern France last Saturday confirms the findings of the postgraduate research currently being conducted by Gideon Lopes Cardozo at the Université Louis Pasteur in Strasbourg and the Faculty of Earth and Life Sciences at the VU Amsterdam. Lopes Cardozo is investigating the causes of earthquakes... view more... (2003-02-27)
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)
Earthquake faults lost and found @ the London `Catastrophes` conference
Three great earthquakes during the winter of 1811-1812 struck eastern North America, causing widespread destruction in the northern Mississippi river valley, and even causing the Mississippi River to divert. Though the estimated magnitudes of the earthquakes are between 7 and 8+, no definitive surface rupture has ever been identified. Instead,... view more... (2002-08-17)
Folded sediment unusual in Sumatran tsunami area
Sediment folding may have added to the exceptionally large tsunami that struck Sumatra on Dec. 26, 2004, according to an international team of geologists. "Tsunami models consider the rebound of the plate during the earthquake, but do not include permanent deformation, like folding, of the upper plate." says Dr. Donald M. Fisher,... view more...

New Hebrew University frictional motion study could provide tool for earthquake prediction
A new study on "waves (or fronts) of detachment" involved in the process of friction offers a new perspective on an old scientific puzzle and could provide a key to improving predictions of future earthquakes, say scientists at the Hebrew University of Jerusalem. view more (2004-09-26)
Fragmented Structure of Seafloor Faults May Dampen Effects of Earthquakes
Many earthquakes in the deep ocean are much smaller in magnitude than expected. Geophysicists from the Woods Hole Oceanographic Institution (WHOI) have found new evidence that the fragmented structure of seafloor faults, along with previously unrecognized volcanic activity, may be dampening the effects of these quakes. view more (2007-07-13)
Silent earthquakes may foreshadow destructive temblors, study finds
A team of American geoscientists is urging colleagues around the world to search for evidence of tiny earthquakes in seismically active areas, such as the Pacific Northwest, that are periodically rocked by powerful temblors of magnitude 8 and higher. view more (2006-07-06)
Ground movement risks identified by Terrafirma
Ground movements are responsible for hundreds of deaths and billions of Euros annually, and the threat they pose is increasing due to urbanisation and land use. ESA's GMES Service Element Programme is backing a project, Terrafirma, to help mitigate these risks. view more (2006-09-11)
Fire under the ice
An international team of researchers was able to provide evidence of explosive volcanism in the deeps of the ice-covered Arctic Ocean for the first time. view more (2008-06-26)
Pacific tsunami threat greater than expected
The potential for a huge Pacific Ocean tsunami on the West Coast of America may be greater than previously thought, according to a new study of geological evidence along the Gulf of Alaska coast. view more (2009-07-21)
San Andreas earthquake observatory achieves milestone as drillers penetrate the active fault zone
The San Andreas Fault Observatory at Depth (SAFOD) reached a significant goal on Aug. 2 when scientists drilled into a seismically active section of the fault approximately two miles below the surface of the Earth. view more (2005-08-04)
Rising tides intensify non-volcanic tremor in Earth's crust
For more than a decade geoscientists have detected what amount to ultra-slow-motion earthquakes under Western Washington and British Columbia on a regular basis, about every 14 months. view more (2007-11-26)
Complex structure observed in Tonga mantle wedge has implications for the evolution of volcanic arcs
The subduction zones where oceanic plates sink beneath the continents produce volcanic arcs such as those that make up the "rim of fire" around the Pacific Ocean. view more (2007-04-13)
Simple method strengthens schools, other buildings against earthquakes
Civil engineers using a specialized laboratory at Purdue University have demonstrated the effectiveness of a simple, inexpensive method to strengthen buildings that have a flaw making them dangerously vulnerable to earthquakes. view more (2009-02-11)
May 2008 earthquake in China could be followed by another significant rupture
Researchers analyzing the May 2008 Wenchuan earthquake in China's Sichuan province have found that geological stress has significantly increased on three major fault systems in the region. view more (2008-09-11)
Tremors on southern San Andreas Fault may mean increased earthquake risk
Increases in mysterious underground tremors observed in several active earthquake fault zones around the world could signal a build-up of stress at locked segments of the faults and presumably an increased likelihood of a major quake, according to a new University of California, Berkeley, study. view more (2009-07-10)
UK e-Science project discovers new knowledge about earthquakes
A UK e-Science project is revealing new scientific insights into earthquakes. Technologies developed under the Discovery Net project are enabling geophysicists to combine two different methods of studying earthquakes and so discover new knowledge that would not have been revealed using one method alone. view more (2005-11-28)
Researchers learn from analyses of rare tsunami earthquake
Analyses of a classic, slow-rupturing tsunami earthquake whose massive waves devastated the coast of Java, Indonesia, this past summer are providing insight to seismologists and engineers, who want to better understand these rare events, recommend strategies to improve safety and perhaps provide long-range forecasts of potential danger zones... view more...

Geologist urges seismic shift in process for selecting EarthScope study sites
EarthScope, an enormous, nationwide earth science project, is poised to revolutionize understanding of earthquakes, fault systems, volcanoes and the North American continent's structure. view more (2005-10-17)
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 of North America and traveled to the shores of... view more...
