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)

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)

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)

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)

Scientists aim to unlock deep-sea 'secrets' of Earth's crust
Scientists from Durham University will use robots to explore the depths of the Atlantic Ocean to study the growth of underwater volcanoes that build the Earth's crust.   view more (2008-05-14)

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)

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)

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)

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)

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)

Earthquake 'memory' could spur aftershocks
Using a novel device that simulates earthquakes in a laboratory setting, a Los Alamos researcher and his colleagues have shown that seismic waves-the sounds radiated from earthquakes-can induce earthquake aftershocks, often long after a quake has subsided.   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)

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)

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)

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)

Deep-ocean drilling researchers target earthquake and tsunami zone
Researchers fresh from an eight-week scientific drilling expedition off the Pacific coast of Japan today reported their discovery of strong variation in the tectonic stresses in a region notorious for generating devastating earthquakes and tsunamis, the Nankai Trough.   view more (2007-12-13)

Journey to the center of the earth: Discovery sheds light on mantle formation
Uncovering a rare, two-billion-year-old window into the Earth's mantle, a University of Houston professor and his team have found our planet's geological history is more complex than previously thought.   view more (2008-04-11)

Super deep rock formation and upper mantle move in concert
European Highlight from Geophysical Research Letters (GRL) In a finding that contradicts conventional wisdom, results from a new technique to survey the super-deep upper mantle of southern Africa show that underground volcanic rock shifted with the lithospheric plates in the area. Previously,... view more (2002-03-06)

More economical and easier to install wind generator: the wind reservoir
Two Basque companies, Enerlim and NECESA, have developed a new wind generator, a wind reservoir to make use of wind energy. This wind reservoir is much lighter than ordinary three-arm wind generators; hence, it is more economical and easier to install. On the other side, the machine is completely... view more (2002-03-25)

Low-cost microfluidics can be a sticky problem
A deceptively simple approach to bonding thermoplastic microchannel plates together with solvent could be used for low-cost, high-volume production of disposable "lab-on-a-chip" devices, according to researchers from the National Institute of Standards and Technology (NIST) and George... view more (2006-05-15)

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)

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)

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)

UF study: Isthmus of Panama formed as result of plate tectonics
Contrary to previous evidence, a new University of Florida study shows the Isthmus of Panama was most likely formed by a Central American Peninsula colliding slowly with the South American continent through tectonic plate movement over millions of years.   view more (2008-07-30)

CARBON FIBRE COULD HELP BEAT TRAFFIC JAMS
Thin sheets of carbon fibre could provide a new way of repairing bridges quickly and increasing their life-span. The technique would also reduce the disruption to traffic caused by conventional repair techniques.   view more (1999-05-20)
