Jessica DePaolis (second from left) and the team of researchers studied and compared sedimentary core samples in Montague Island, Alaska, and found evidence that four of the past eight earthquakes ...

Recent seismic imaging off Vancouver Island has revealed something extraordinary: a tear in the subducting oceanic plate beneath the Cascadia Subduction Zone. The finding briefly raised the public's ...

The pressure keeps building below the Earth’s surface off the coast of the Pacific Northwest, and a multi-layered disaster could strike at any time. A huge earthquake is brewing along the Cascadia ...

On Jan. 26, 1700, one of the largest earthquakes in human history struck off the West Coast of the United States, causing a tsunami and significant changes to the coastline from southern British ...

Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in ...

EUGENE, Ore. (NBC) -- When an earthquake rips along the Cascadia Subduction Zone fault, much of the U.S. West Coast could shake violently for five minutes, and tsunami waves as tall as 100 feet could ...

Oceans are subject to continuous change, mostly over extremely vast periods of time running into millions of years. Researchers have now used computer simulations to demonstrate that a subduction zone ...

Marine geophysicists just published the widest survey of the Cascadia Subduction Zone to date. The Cascadia Subduction Zone is a fault located off the Pacific Coast shoreline, from Northern California ...
