This area, called the Cascadia Subduction Zone, hosts a megathrust fault ... a marine geophysicist at Columbia University's ...

Discover interesting facts about how big earthquakes can get, why earthquakes happen, and why they're so hard to predict.

Plates at subduction zones typically move just a few centimeters ... the plates can slip several meters and cause some of Earth's largest earthquakes. The timing and location of such megathrust ...

Subduction zones are regions where a tectonic plate is diving under another plate. In these seams where the plates meet each other, magma from Earth's mantle has the opportunity to rise to the ...

Plate tectonics give Earth its mountains, earthquakes, continental drift and maybe even helped give rise to life itself. But do other planets in the solar system have them too?

I recently participated in a three-week-long, National Science Foundation-funded research cruise to the Mariana Trench. Our ...

The Earth's mantle, the layer between the crust and the core, is the stage for slow but powerful movements. These movements, called convection, are responsible for plate tectonics. Oceanic plates, ...
