Subduction zones—places where one tectonic plate dives beneath another—are where the world's largest and most damaging earthquakes occur. A new study has found that when underwater mountains—also known as seamounts—are ...

Do tectonic plates move because of motion in the Earth's mantle, or is the mantle driven by the movement of the plates? Or could it be that this question is ill-posed? This is the point of view adopted by scientists at the ...

By combining models of magnitude 9 to 9.2 earthquakes on the Cascadia Subduction Zone with geological evidence of past coastal changes, researchers have a better idea of what kind of megathrust seismic activity was behind ...

A new study from Caltech finds that so-called "slow slip" or "silent" earthquakes behave more like regular earthquakes than previously thought. The discovery opens the door for geoscientists to use these frequent and nondestructive ...

Convection in Earth's mantle is the "engine" driving plate tectonics. Hot material rises to the Earth's surface from the boundary between the planet's core and mantle, at a depth of about 3000 kilometers. Cold material then ...
