New system can warn of tsunamis within minutes
Seismologists have developed a new system that could be used to warn future populations of an impending tsunami only minutes after the initial earthquake. The system, known as RTerg, could help reduce the death toll by giving ...
Researchers release first large observational study of 9.0 Tohoku-Oki earthquake
When the magnitude 9.0 Tohoku-Oki earthquake and resulting tsunami struck off the northeast coast of Japan on March 11, they caused widespread destruction and death. Using observations from a dense regional ...
Breakthrough achieved in explaining why tectonic plates move the way they do
A team of researchers including Scripps Institution of Oceanography, UC San Diego geophysicist Dave Stegman has developed a new theory to explain the global motions of tectonic plates on the earth's surface.
Seismic experiment in Alaska could shed light on slow earthquakes
An earthquake expert at the University of California, Riverside is leading a team of seismologists and volcanologists to conduct an experiment in Alaska that will record a variety of seismic events in that ...
Rising above the risk: America's first tsunami refuge
Washington's coast is so close to the seismically active Cascadia Subduction Zone that if a megathrust earthquake were to occur, a tsunami would hit the Washington shoreline in just 25 minutes.
Subduction zones reveal sulphur cycle and mineral potential
Reasearch led by West Australian scientists into 'subduction' during tectonic plate collisions has provided new insights into the global sulphur cycle.
M 9.0+ possible for subduction zones along 'Ring of Fire,' study suggests
The magnitude of the 2011 Tohoku quake (M 9.0) caught many seismologists by surprise, prompting some to revisit the question of calculating the maximum magnitude earthquake possible for a particular fault. New research offers ...
Japan ignores skeptics, keeps goal of earthquake prediction
In a nondescript government building near the Imperial Palace, a team of Japanese seismologists stands ready to predict an earthquake.
New data: Mega-quake could strike near Seattle
Using sophisticated seismometers and GPS devices, scientists have been able to track minute movements along two massive tectonic plates colliding 25 miles or so underneath Washington state's Puget Sound basin. Their early ...
Odds are about 1-in-3 that a mega-earthquake will hit the Northwest in the next 50 years
The major earthquakes that devastated Chile earlier this year and which triggered the catastrophic Indonesian tsunami of 2004 are more than just a distinct possibility to strike the Pacific Northwest coast of the United States, ...
New study highlights California tsunami risk
More than a quarter of a million Californians live in coastal areas which could be hit by devastating floods from a major tsunami in the quake-prone US state, a new study says.
Earth's mantle flows fast
(PhysOrg.com) -- The Earth's mantle flows far more rapidly around a sinking tectonic plate than previously thought, according to new computer modeling by UC Davis geologists. The findings could change the ...
Systematic shifts in subducting slab behavior with depth
When tectonic plates collide, the less buoyant plate will, in some cases, be forced beneath the other. At such subduction zones the sinking tectonic plate, known as a slab, does not follow a simple path from the surface to ...
'Odd duck' Indonesia quake surprises scientists
(AP) -- The massive earthquake off Indonesia surprised scientists: Usually this type of jolt isn't this powerful.
