Sediment could be a major factor in biggest subduction zone earthquakes
The most powerful earthquakes - such as those that shook Indonesia in 2004, Alaska in 1964, Chile in 1960 and the Pacific Northwest in 1700 - occur in subduction zones, areas of the sea floor just offshore where two tectonic plates meet and one dives beneath the other.   view more (2006-01-31)

Sediment layer may forecast greatest earthquakes
Researchers at Yale and the University of Washington report that great earthquakes, like the 2004 Sumatra earthquake, may be caused by the build up of sediment on top of subduction zones, suggesting a new way to forecast these most severe earthquakes.   view more (2006-01-31)

Hazard mitigation can save money
An ounce of prevention may actually be worth a pound of cure, especially if the actions taken are to reduce losses from natural hazards, such as tornados, hurricanes or flooding, according to a Penn State researcher.   view more (2006-01-23)

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)

Research tracks whales by listening to sounds
Researchers have developed a new tool to help them study endangered whales - autonomous hydrophones that can be deployed in the ocean to record the unique clicks, pulses and calls of different whale species.   view more (2006-01-03)

Ancient glaciers still affect the shape of North America, say scientists
Long after the disappearance of the glaciers that once covered much of North America, the land they rested upon is still recovering from their weight - and the slow movement of this recovery includes horizontal motion never seen before.   view more (2005-12-15)

Prelude to an Earthquake?
A geophysicist from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has identified possible seismic precursors to two recent California earthquakes, including the 1989 Loma Prieta earthquake that wreaked havoc throughout the Bay Area.   view more (2005-12-12)

Large Himalaya earthquakes may occur sooner than expected
While the rupture zones of recent major earthquakes are immune to similar-sized earthquakes for hundreds of years, they could be vulnerable to even bigger destructive temblors sooner than scientists suspect.   view more (2005-12-08)

Getting ready for the 'big one,' researchers make most detailed survey ever of San Adreas Fault
Researchers have completed the most meticulous survey ever made of the San Andreas Fault, and they've found detailed features that nobody could have seen before.   view more (2005-12-07)

A century after 1906 earthquake, geophysicists revisit 'Big One' and come up with new model
Almost a century after the 1906 earthquake, Stanford geophysicists have revisited San Francisco's ''Big One'' and now paint a new picture of a fault that was ready to go and that ruptured farther and faster than previously supposed.   view more (2005-12-06)

San Andreas Fault Observatory at Depth reveals new insights into the 'earthquake machine'
The San Andreas Fault Observatory at Depth (SAFOD)-the first underground observatory to provide physical samples and real-time seismological data from deep inside an active fault zone-is yielding surprising new clues about the origin of earthquakes.   view more (2005-12-06)

Huge tsunami spurred progress, revealed needs
The catastrophic tsunami that struck Indonesia and East Asia almost a year ago has done much to heighten the interest, research programs and preparations in the United States for events of this type, but experts say there are areas that need more attention and challenges yet to be met.   view more (2005-12-05)

Earthquake 'pulses' could predict tsunami impact
The magnitude 9.2 earthquake that triggered a devastating tsunami in the Indian Ocean in December of 2004 originated just off the coast of northern Sumatra, but an "energy pulse" - an area where slip on the fault was much greater - created the largest waves, some 100 miles from the... view more (2005-12-05)

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... view more (2005-11-28)

First few seconds of earthquake rupture provides data for distant shake warnings
A University of California, Berkeley, seismologist has discovered a way to provide seconds to tens of seconds of advance warning about impending ground shaking from an earthquake.   view more (2005-11-10)

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)

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)

Earth's core rotates faster than its crust, scientists say
Scientists have ended a 9-year-old debate by proving that Earth's core rotates faster than its surface, by about 0.3 to 0.5 degree per year.   view more (2005-08-26)

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)

A new discovery helps us to understand the complex nature of earthquakes
Álvaro Corral, a physicist at the Universitat Autònoma de Barcelona, has discovered that the structure of the recurrence time of earthquakes, which is the time interval between successive earthquakes, is similar to the spatial structure of physics systems when they change phase... view more (2005-07-11)

Mountain-building process much faster - and cooler - than previously thought, say Queen's geologists
Geologists at Queen's University have discovered that the time it takes for mountain ranges to form is millions of years shorter than previously thought.   view more (2005-07-01)

Permanent deep-sea seismic sensors
A submarine seismic sensor was recently set in place at 2400 m depth, off Toulon. The instrument was attached to a neutrino telescope developed by the international scientific programme Antares.   view more (2005-06-06)

A third of Britons would forfeit flying abroad"¦
The annual exodus of 'Brits abroad' is under threat, as a third of Britons claim they would give up flying if it solved the global climate crisis, according to new research released today by the Dana Centre in London.   view more (2005-04-19)

Green light for Lazio-Sirad: the experiment on the International Space Station that will chase earthquakes
Lazio-Sirad is ready to gather data. The experiment is installed on the International Space Station and its aim is to trace the slight variations of the so-called Van Allen belts that seem to occur before earthquakes. At the same time the experiment will gather data that will make possible the... view more (2005-04-14)

New Method For Dating Ancient Earthquakes Through Cave Evidence Developed By Israeli Researchers
A new method for dating destructive past earthquakes, based on evidence remaining in caves has been developed by scientists at the Hebrew University of Jerusalem and the Geological Survey of Israel.   view more (2005-04-11)
