Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

PORTLAND, Ore. (KOIN) – A new study mapping the Cascadia Subduction Zone is giving scientists clues about the state of the fault line as the Pacific Northwest awaits a potentially catastrophic ...

SEATTLE — Newly-released research led by the University of Washington (UW) showed that a feature scientists hypothesized was present along the Cascadia Subduction Zone is missing in places. What does ...

PORTLAND, Ore. (KATU) — Friday marked the 324th anniversary of the Cascadia earthquake. Doug Toomey with the University of Oregon says about 20 to 30 years ago, geologists along the coast noticed ...

Groundbreaking research has provided new insight into the tectonic plate shifts that create some of the Earth's largest earthquakes and tsunamis. Groundbreaking research has provided new insight into ...

Subduction zones are the most important sites of material exchange between the crust and mantle on Earth. They are also the locations where the largest deposits of strategic metals, such as copper, ...

SEATTLE — Friday marks the anniversary of the last major earthquake in the Pacific Northwest when the Cascadia Subduction Zone went off 324 years ago. Since then, Washington has seen smaller ...

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 ...

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 barrel toward shore.

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 ...
