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.

Geologists have uncovered the remains of a massive tectonic plate beneath the Pacific Ocean, a plate that had been hidden for ...

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 ...

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 ...

Map highlighting the Atlantic subduction zones, the fully developed Lesser Antilles and Scotia arcs on the western side and the incipient Gibraltar arc on the eastern side. From Duarte et al ...

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.

PORTLAND, Ore. (KTVZ) — Around 9 p.m. on January 26th, 1700, a powerful magnitude 9.0 earthquake struck along the Cascadia Subduction Zone, which extends from Vancouver Island in British ...

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.

The map of the Cascadia Subduction Zone showed several interesting findings. First, it confirmed a previous theory that "smaller, horizontal faults cut through both the upper and lower plates ...

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.
