Deep beneath Alaska's Aleutian Islands, down where the pressure and temperatures have become so high that rock starts to flow, new continental crust is being born.
Make no mistake. Once a tsunami has formed, it cannot be stopped. But those in charge of keeping communities safe when one strikes should listen to experts' warning signs and take the necessary precautions to prevent an already ...
Geologists from Brown University may have finally explained what triggers certain earthquakes that occur deep beneath the Earth's surface in subduction zones, regions where one tectonic plate slides beneath another.
As military helicopters ferry search and rescue teams over the Pacific Northwest, below them are scenes of devastation from a giant earthquake that could strike the region at any time.
Research teams have evaluated the major 7.8 magnitude subduction zone earthquake in Gorkha, Nepal, in April 2015, and identified characteristics that may be of special relevance to the future of the Pacific Northwest.
The bottom of the ocean just keeps getting better. Or at least more interesting to look at.
One of the big mysteries in the history of the Earth is the development of plate tectonics. When exactly did these processes begin? Scientific opinion varies widely.
New geophysical data show that fault slip during the March 2005 magnitude 8.7 (Mw) earthquake off the west coast of northern Sumatra, Indonesia (also referred to as the Simeulue-Nias earthquake), was stopped by the topography ...
A new study suggests that the common belief that the Earth's rigid tectonic plates stay strong when they slide under another plate, known as subduction, may not be universal.
"Knowing what a chicken looks like and what all the chickens before it looked like doesn't help us to understand the egg," says Taras Gerya. The ETH Professor of Geophysics uses this metaphor to address plate tectonics and ...
