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.

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 ...

Caption 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 ...

Bringing a novel approach to a classic problem, researchers have revealed how changes in ocean chemistry over the past 2 billion years have left an imprint on volcanic rocks formed in island arcs ...

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 ...

Did you know the Ring of Fire, a horseshoe-shaped zone around the Pacific Ocean, has about 750 to 915 active or dormant ...

A subduction zone, composed of the deep Aleutian Trench coupled with a landward line of volcanoes, creates a series of offshore islands (the Aleutians) as well as a line of volcanoes along the ...

Recent research report by Live Science suggests that a dormant subduction zone beneath the Gibraltar Strait may awaken, potentially leading to the creation of a new geological phenomenon akin to ...
