Scientists probe link between magnetic polarity reversal and mantle processes
Aug 03, 2012 (SPX)
Scientists at the University of Liverpool have discovered that variations in the long-term reversal rate of the Earth's magnetic field may be caused by changes ...
Magnetic field, mantle convection and tectonics
Aug 02, 2012 (SPX)
On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of ...
Alpine faults show new evidence for regular magnitude 8 earthquakes
Jul 31, 2012 (SPX)
A new study published in the prestigious journal Science, co-authored by University of Nevada, Reno's Glenn Biasi and colleagues at GNS Science in New Zealand, ...
Colliding continents affected climate
Jul 23, 2012 (UPI)
An alteration of seawater chemistry caused by a continental collision 50 million years ago has been linked with past climate changes, researchers say. "Seawater...
Deep tremors are possible earthquake clues
Jul 05, 2012 (UPI)
A recently discovered form of deep seismic activity may provide clues about destructive earthquakes that occur at shallower depths, European researchers say. Te...
Curvy Mountain Belts
Jul 03, 2012 (SPX)
Mountain belts on Earth are most commonly formed by collision of one or more tectonic plates. The process of collision, uplift, and subsequent erosion of long m...
New observations on the San Andreas Fault in Santa Cruz Mountains, Seattle Fault Zone
Jun 04, 2012 (SPX)
Recent paleoseismic work has documented four surface-rupturing earthquakes that occurred across the Santa Cruz Mountains section of the San Andreas Fault (SAF) ...
Landslides linked to plate tectonics create the steepest mountain terrain
Jun 01, 2012 (SPX)
Some of the steepest mountain slopes in the world got that way because of the interplay between terrain uplift associated with plate tectonics and powerful stre...
Double quake highlights Italy's seismic perils
May 29, 2012 (AFP)
Two killer earthquakes that struck northeastern Italy in nine days have shed light on the brutal but complex seismic forces that grip the Italian peninsula, sci...
Secret soil cracks linger, despite surface sealing
May 24, 2012 (SPX)
Deep cracks in soil can remain open underground even after they have visibly sealed on the surface, a new study has found. The results could have important impl...
Caltech researchers gain greater insight into earthquake cycles
May 16, 2012 (SPX)
For those who study earthquakes, one major challenge has been trying to understand all the physics of a fault-both during an earthquake and at times of "rest"-i...
Parts of Mt Fuji 'could collapse' if fault shifts
May 11, 2012 (AFP)
Parts of Japan's Mount Fuji, a national symbol and key tourist attraction, could collapse if a newly-discovered faultline under the mountain shifts, a governmen...
Rapid Sierra Nevada uplift tracked by scientists
May 10, 2012 (SPX)
Hammond's team includes Geoff Blewitt, Hans-Peter Plag and Corne Kreemer from the University of Nevada, Reno's College of Science and Zhenhong Li of the Centre ...
Signs of three major Japan quakes before 2011: researchers
Apr 25, 2012 (AFP)
Three major earthquakes seem to have occurred in northern Japan before it was hit in March 2011 by a massive quake and tsunami, researchers said Wednesday based...
Volcanic plumbing provides clues on eruptions and earthquakes
Apr 16, 2012 (SPX)
Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to understanding plate ruptures and predicting eruptions-both...
Scientists Find Slow Subsidence of Earth's Crust Beneath the Mississippi Delta
Apr 09, 2012 (SPX)
The Earth's crust beneath the Mississippi Delta sinks at a much slower rate than what had been assumed. That's one of the results geoscientists report in a pape...
Richard Branson headed to 'center of Earth'
Mar 30, 2012 (AFP)
British tycoon Richard Branson may have lost his race to the bottom of the ocean, but not his sense of humor, declaring Friday a faux plan to top his rivals by ...
Scientists suggest new age for East African Rift
Mar 29, 2012 (SPX)
The Great Rift Valley of East Africa-the birthplace of the human species-may have taken much longer to develop than previously believed, according to a new stud...

Mar 29, 2012 (SPX)
Scientists recently concluded an expedition aboard the research vessel JOIDES Resolution to learn more about Atlantis Massif, an undersea mountain, or seamount,...
Geologists correct a rift in Africa
Mar 29, 2012 (SPX)
The huge changes in the Earth's crust that influenced human evolution are being redefined, according to research published in Nature Geoscience. The Great Rift ...
