A subduction zone is created where two plates converge, with one sinking into the mantle. Dynamics along the plate interface create earthquakes, magma generated above the sinking slab leads to ...

Hidden off the US Western shore, beneath the Pacific Ocean, is the Cascadia Subduction Zone. This fault is capable of ...

The Cascadia Subduction Zone is capable of generating powerful earthquakes. The study found compact sediments along the coast of Washington and northern Oregon, a result that suggests that the ...

The Cascadia subduction zone, where the oceanic Juan de Fuca plate descends beneath the overlying North American plate, extends 1100 km from northern California to northern Vancouver Island.

More specifically, subduction zones — where tectonic plates slip over and under each other — can push land to open or close oceans. Researchers found that an inactive subduction zone under the ...
