(CBS News) A new study suggests that two recent earthquakes may indicate a literal seismic shift in our understanding of tectonic plate movements. Massive earthquakes under the Indian Ocean that took ...

For the first time ever, scientists have gotten a full picture of the plate that is pushing its way under the Pacific Northwestern coast and putting the entire region in danger of a devastating ...

Along submarine mountain ranges, the mid-ocean ridges, forces from the Earth's interior push tectonic plates apart, forming new ocean floor and thus moving continents about. However, many features of ...

The first ruptures in early Earth’s skin formed because of the weakness of rock minerals merely a millimeter wide, two scientists propose. The small minerals’ behavior created boundaries defining ...

• Due to a lack of data, the studies available so far underestimated the seismic and tsunami risk of these large faults. A new study led by the Institut de Ciències del Mar (ICM-CSIC) in Barcelona and ...

Scientists have identified a long-lost tectonic plate in the west Pacific Ocean. Called Pontus, the 'mega-plate' was once 15 million square miles, about a quarter the size of the Pacific Ocean today.
