Volcano-like tremors detected deep within Earth's crust near San Andreas
Tremors within the Earth are usually-but not always-related to the activity of a volcano. Now, such vibrations have been recorded nowhere near a volcano, but at a geologic observatory at the San Andreas Fault.   view more (2006-04-13)

Measurements link magma melting rate to tectonic plate subduction rate
Determining the origin and rate of magma production in subduction zone volcanoes is essential to understanding the formation of continental crust and the recycling of subducted materials back into Earth's mantle.   view more (2007-11-09)

Plate tectonics may take a break
Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair.   view more (2008-01-04)

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)

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)

Earth's Moving Crust May Occasionally Stop
The motion, formation, and recycling of Earth's crust-commonly known as plate tectonics-have long been thought to be continuous processes. But new research by geophysicists suggests that plate tectonic motions have occasionally stopped in Earth's geologic history, and may do so again. The findings... view more (2008-01-10)

Sumatra megaquake defied theory
The risks of Sumatra-style mega-quakes around the world have been sorely misjudged, say earth scientists who are re-examining some of the pre-December 2004 assumptions scientists made about such rare events.   view more (2006-03-28)

Scientists use seismic waves to locate missing rock under Tibet
Geologists at the University of Illinois at Urbana-Champaign have located a huge chunk of Earth's lithosphere that went missing 15 million years ago. By finding the massive block of errant rock beneath Tibet, the researchers are helping solve a long-standing mystery, and clarifying how continents... view more (2007-02-08)

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)

UCL scientists create first earthquakes in the laboratory
Scientists at UCL have recreated earthquakes in the laboratory for the first time allowing them to better understand the origin of the largest and most violent earthquakes. This is the first time scientists have been able to generate and observe deep and intermediate focus earthquakes in the... view more (2002-11-14)

Pacific Northwest tectonic plates are moving
he three major tectonic plates off the Pacific Northwest coast are undergoing a gradual shift, and the area in which they converge - popularly known as the "Triple Junction" - appears to be migrating in a southeasterly direction.   view more (2006-04-12)

Deep-ocean researchers target tsunami zone near Japan
Rice University Earth scientist Dale Sawyer and colleagues last month reported the discovery of a strong variation in the tectonic stresses in a region of the Pacific Ocean notorious for generating devastating earthquakes and tsunamis in southeastern Japan.   view more (2008-01-18)

Journey to the center of the Earth -- Imperial scientists explain tectonic plate motions
The first direct evidence of how and when tectonic plates move into the deepest reaches of the Earth is published in Nature today. Scientists hope their description of how plates collide with one sliding below the other into the rocky mantle could potentially improve their ability to assess... view more (2008-02-22)

Scientists obtain core samples from subsea fault system off Japan
The third expedition of the Integrated Ocean Drilling Program's Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) completed its mission off the Kii Peninsula today.   view more (2008-02-06)

1 year after Solomon Islands, scientists learn barrier to earthquakes weaker than expected
On the one year anniversary of a devastating earthquake and tsunami in the Solomon Islands that killed 52 people and displaced more than 6,000, scientists are revising their understanding of the potential for similar giant earthquakes in other parts of the globe.   view more (2008-04-03)

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)

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)

2002 Alaskan quake left 7 areas of California stirred but not shaken
Earth tremors not linked to volcanic activity first turned up in seismic observations several years ago, but those tremors were almost exclusively in subduction zones such as the Cascadia region off the coast of the Pacific Northwest.   view more (2007-11-26)

Hot climate could shut down plate tectonics
A new study of possible links between climate and geophysics on Earth and similar planets finds that prolonged heating of the atmosphere can shut down plate tectonics and cause a planet's crust to become locked in place.   view more (2008-05-13)

Reconstruction of a giant submarine slope-failure on the northern edge of New Zealand
The continental margins, submarine areas at the boundary between the continent and the oceanic abyssal floor are unstable. This instability is manifested by submarine slides or collapse events. These are sometimes catastrophic, taking away portions of coast down to the deep ocean floor or locally... view more (2001-04-26)

Is a Russian peninsula really part of North America?
For many years geologists have harbored a belief that the Kamchatka Peninsula, shrouded in mystery and secrecy on Russia's east coast, actually sits on the same tectonic plate as the mainland United States, Canada and Mexico.   view more (2006-05-03)

Tiny tremors and earthquakes provide intriguing clues about seismic activity, study finds
The elusive science of earthquake prediction has been reinvigorated in recent years with the discovery of "non-volcanic tremors"—faint vibrations that originate deep inside active fault zones.   view more (2006-07-13)

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)

Claritas Fossae tectonic region on Mars
These Mars Express images show Claritas Fossae, an ancient tectonic region on Mars, west of Solis Planum, a tectonic and volcanic area south-east of the Tharsis volcano group. The images were taken by the High-Resolution Stereo Camera (HRSC) on Mars in orbit 68 from an altitude of 271 km. The... view more (2004-03-31)
