Researchers took a ship off the coasts of Oregon, Washington, and British Columbia over the summer of 2021 to map the Cascadia Subduction Zone – discovering one plate near Washington is smoother ...

Researchers using new technology to map the Cascadia Subduction Zone off the U.S. West Coast discovered a new danger zone. Here’s where, and why.

Wang hopes to create a more comprehensive map of ancient subduction and upwelling (the geological process that occurs when subducted material heats up and rises to the surface again) zones, as ...

For hundreds of years, the Cascadia subduction zone has been quiet. But on Jan. 26, 1700, the earth shook. Japanese history records show an “orphan” tsunami traveled across the Pacific, with ...

In other subduction zones, scientists often observe small earthquakes frequently, which makes the area easier to map, according to Carbotte. That’s not the case here.

The 1980 eruption cycle made Mount St. Helens one of the most famous volcanoes in the Cascades. But it is far from the only volcano in the range.

Previous research indicates the subduction zone produced earthquakes as big as magnitude 9.0. ... Researchers will map out a strategic plan for the CRESCENT at a kickoff meeting in late October.
