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)
10 questions shaping 21st-century earth science identified
Ten questions driving the geological and planetary sciences were identified today in a new report by the National Research Council. Aimed at reflecting the major scientific issues facing earth science at the start of the 21st century, the questions represent where the field stands, how it arrived at this point, and where it may be headed. view more (2008-03-13)
An active spreading ridge discovered off the Futuna Islands (South-West Pacific)
In the context of a French national research programme on natural hazards, a bathymetric survey was undertaken off the Futuna and Alofi Islands in the South-West Pacific. Its objective was to improve knowledge of deformations of the oceanic lithosphere in this part of the Pacific which suffers intense seismic activity. During the campaign, called... view more...

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)
Tsunami waves reasonably likely to strike Israel
"There is a likely chance of tsunami waves reaching the shores of Israel," says Dr. Beverly Goodman of the Leon H. Charney School of Marine Sciences at the University of Haifa following an encompassing geo-archaeological study at the port of Caesarea. "Tsunami events in the Mediterranean do occur less frequently than in the Pacific... view more... (2009-10-26)
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)
Newly discovered active fault building new Dalmatian Islands off Croatian coast
A newly identified fault that runs under the Adriatic Sea is actively building more of the famously beautiful Dalmatian Islands and Dinaride Mountains of Croatia, according to a new research report. view more (2008-01-23)
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)
A hidden drip, drip, drip beneath Earth's surface
There are very few places in the world where dynamic activity taking place beneath Earth's surface goes undetected. view more (2009-05-27)
A new cloaking method
University of Utah mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in "Star Trek." Instead, the new method someday might shield submarines from sonar, planes from radar, buildings from earthquakes, and oil rigs and coastal structures... view more... (2009-08-17)
Endangered right whales found where presumed extinct
Using a system of underwater hydrophones that can record sounds from hundreds of miles away, a team of scientists from Oregon State University and the National Oceanic and Atmospheric Administration has documented the presence of endangered North Atlantic right whales in an area they were thought to be extinct. view more (2009-05-21)
Yellowstone's Ancient Supervolcano: Only Lukewarm?
The geysers of Yellowstone National Park owe their eistence to the "Yellowstone hotspot"--a region of molten rock buried deep beneath Yellowstone, geologists have found. view more (2008-08-28)
New robot scouts best locations for components of undersea lab
Like a deep-sea bloodhound, Sentry - the newest in an elite group of unmanned submersibles able to operate on their own in demanding and rugged environments - has helped scientists pinpoint optimal locations for two observation sites of a pioneering seafloor laboratory being planned off Washington and Oregon. view more (2008-08-14)
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)
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)
NJIT architect professor advocates best-building practices for high wind regions
More than ever before, building design and construction can be significantly improved to reduce wind pressures on building surfaces and to help better resist high winds and hurricanes in residential or commercial construction, said NJIT architecture professor Rima Taher, PhD. view more (2008-07-10)
Slippery stretching explains ocean floor formation
For the first time, scientists have found regions of the earth's crust which are stretching apart to form new sea floor. view more (2006-07-31)
