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 ...

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 ...

This area, called the Cascadia Subduction Zone, hosts a megathrust fault ... they finally lurch against each other. The result: the world's greatest earthquakes, shaking both seabed and land ...

Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones. As these older sections of plates sink, newer and less dense sections of plate are pulled along behind.

The researchers mapped fault during a 41-day research trip in which a vessel trailed miles-long cable along the fault to listen to the seafloor and map an image of the subduction zone. Study ...
