Tectonic plates act like variable thermostat
Like a quilt that loses heat between squares, the earth's system of tectonic plates lets warmth out at every stitch.   view more (2007-08-14)

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)

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... view more (2007-07-13)

Scientists report study results from 'stealth' tsunami that killed 600 in Java last summer
Though categorized as magnitude 7.8, the earthquake could scarcely be felt by beachgoers that afternoon. A low tide and wind-driven waves disguised the signs of receding water, so when the tsunami struck, it caught even lifeguards by surprise.   view more (2007-06-19)

Geoscience converges under pressure
The contents of the deep Earth affect the planet as a whole, including life at its surface, but scientists must find unusual ways to "see" it.   view more (2007-05-22)

Tracking a hot spot
Using a state-of-the-art satellite imagery technique, researchers are able to more precisely predict volcanic activity, bringing them steps closer to understanding where an eruption may occur.   view more (2007-05-18)

Faster and better emergency response through satellite telecoms
When emergency teams are well informed and governments can coordinate their efforts, lives and property can be saved.   view more (2007-05-10)

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)

High-resolution images herald new era in Earth sciences
High-resolution images that reveal unexpected details of the Earth's internal structure are among the results reported by MIT and Purdue scientists in the March 30 issue of Science.   view more (2007-04-09)

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)

Experts at Nevada develop technology to increase effectiveness of tsunami warning systems
Scientists at the University of Nevada, Reno are at the forefront on a number of seismological fields, including helping the world better determine whether an earthquake is big enough to generate an ocean-wide tsunami.   view more (2007-04-03)

The next great earthquake
The 2004 Sumatra-Andaman earthquake and resulting tsunami are now infamous for the damage they caused, but at the time many scientists believed this area was unlikely to create a quake of such magnitude.   view more (2007-03-23)

Scientists explain source of mysterious tremors emanating from fault zones
Tiny tremors and temblors recently discovered in fault zones from California to Japan are generated by slow-moving earthquakes that may foreshadow catastrophic seismic events, according to scientists at Stanford University and the University of Tokyo.   view more (2007-03-15)

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)

Yellowstone's quiet power
A 17-year University of Utah study of ground movements shows that the power of the huge volcanic hotspot beneath Yellowstone National Park is much greater than previously thought during times when the giant volcano is slumbering.   view more (2007-03-01)

University of Nevada scientists gauge earthquake hazards through study of precariously balance rocks
A seismological research team from the University of Nevada, Reno is finding ways to make precariously balanced rocks talk. In so doing, they are unlocking valuable scientific information in assessing seismic hazards in areas throughout the West.   view more (2007-03-01)

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)

New data shakes accepted models of collisions of the Earth's crust
New research findings may help refine the accepted models used by earth scientists over the past 30 years to describe the ways in which continents clash to form the Earth's landscape.   view more (2007-02-08)

Major population centers may be at risk; building codes must reflect new seismic data
Earthquakes in stable continental regions lack sufficient understanding to prepare local populations for future seismic activity, according to a paper published in the February issue of the Bulletin of the Seismological Society of America (BSSA).   view more (2007-02-08)

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... view more (2007-02-05)

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)

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)

Researchers complete seismic borehole in Kentucky
Drilling has been completed on the deepest borehole for seismic instruments in the eastern U.S. The four-inch diameter hole for the Central U.S. Seismic Observatory (CUSSO), located at Sassafras Ridge in Fulton County, Kentucky, reached a depth of 1,948 feet, where bedrock was encountered.   view more (2006-12-14)

New evidence shows New Madrid Seismic Zone may be cold and dying
New results about the temperatures of rock deep below the New Madrid Seismic Zone in the central United States shed light on the puzzling questions of why large earthquakes happened there in 1811 and 1812 and when they may happen again.   view more (2006-12-12)

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... view more (2006-12-07)
