Ancient Magma Superpiles May Have Shaped The Continents Columbus OH (SPX) Dec 30, 2008 
Two giant plumes of hot rock deep within the earth are linked to the plate motions that shape the continents, researchers have found. The two superplumes, one beneath Hawaii and the other beneath Africa, have likely existed for at least 200 million years, explained Wendy Panero, assistant professor of earth sciences at Ohio State University. The giant plumes - or "superpiles" as Pane ... read moreThe Key Event That Breaks Continents Apart 
West Lafayette IN (SPX) Dec 11, 2008Researchers have captured for the first time a geological event considered key in shaping the Earth's landscape. Dyking events have been reported in the thin oceanic crust but had never been directly observed and quantified in the thicker areas of the planet's shell, Calais said. ... more

Plate Tectonics Started Over Four Billion Years Ago
Los Angeles CA (SPX) Dec 02, 2008A new picture of the early Earth is emerging, including the surprising finding that plate tectonics may have started more than 4 billion years ago - much earlier than scientists had believed, according to new research by UCLA geochemists reported in the journal Nature. "We are proposing that there was plate-tectonic activity in the first 500 million years of Earth's history," said ... more Glacial Erosion Changes Internal Mountain Structure 
Blacksburg VA (SPX) Nov 25, 2008Intense glacial erosion has not only carved the surface of the highest coastal mountain range on earth, the spectacular St. Elias range in Alaska, but has elicited a structural response from deep within the mountain. This interpretation of structural response is based on real-world data now being reported, which supports decades of model simulations of mountain formation and evolution ... more Understanding Europe's Topography 
Paris, France (SPX) Nov 24, 2008Europe's shape is in a constant change: The Mediterranean basin is shrinking, the Alps are rising and pushing North, and Scandinavia is still rebounding after having been crushed by the weight of a thick and huge ice sheet in the ice ages. But what did Europe look like in the past, what are the processes controlling all these changes and what has the future in store for us? And how does ... more Deep magma controls eruption cycles 
State College, Pa. (UPI) Oct 9, 2008 An international team of scientists studying the Soufriere Hills volcano in the Caribbean's Leeward Islands has found deep magma controls eruption cycles. While the volcano exhibits cycles of eruption and quiet, the scientists discovered magma is continuously supplied from deep in the Earth's crust, but a valve acts below a shallower magma chamber, releasing lava to the surface ... more

Isthmus Of Panama Formed As Result Of Plate Tectonics
Gainesville FL (SPX) Aug 01, 2008Contrary 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. The study, co-authored by Florida Museum of Natural History researchers Michael Kirby, Douglas Jones and Bruce MacFadden, is published in ... more Mud Pots Signal Possible Extension Of San Andreas Fault 
Washington DC (SPX) Aug 01, 2008A linear string of mud pots and mud volcanoes suggest surface evidence for a southern extension of the San Andreas Fault that runs through the Salton Sea, according to a paper published in the August issue of the Bulletin of the Seismological Society of America (BSSA). Researchers David K. Lynch and Kenneth W. Hudnut of USGS report the results of a comprehensive survey of mud pots in the a ... more New technique may help predict quakes: study 
Paris (AFP) July 9, 2008Scientists in the United States have devised a method for measuring changes in the speed of seismic waves that could one day help predict earthquakes, a study said Wednesday. In experiments conducted at the San Andreas Fault Observatory at Depth (SAFOD) in Parkfield, California, Fenglin Niu and colleagues measured the speed of so-called shear waves -- "S-waves" -- before, during and after ... more Japan beefs up undersea quake monitoring system 
Yokohama, Japan (AFP) July 3, 2008Japan, one of the most tremor-prone countries in the world, started work Thursday to beef up its undersea earthquake monitoring system. The system will be placed 1,000 to 2,000 metres (3,280-6,562 feet) beneath the ocean surface to gather data on seismic activity that will be transmitted by fiber-optic submarine cable to an above-ground observation centre. The cable system will provide ... more
