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 ...

Groundbreaking Discovery in Offshore Sediment Cores Two fault systems on North America's West Coast – the Cascadia subduction ...

Just off the Pacific Northwest coast amid record-breaking heat in 2021, researchers braved oddly cold, stormy seas to study another threat to the region — earthquakes and tsunamis. The team of about ...

Jan. 26, 2025, marks 325 years since the last great earthquake on the Cascadia subduction zone. It’s a time to reflect on what we’ve learned about this largest fault system in the lower 48 states and ...

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 ...

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.

The Pacific Northwest is at risk for a mega-earthquake because of the Cascadia Subduction Zone. The region is primed for powerful quakes, with a particularly strong one called the Big One happening ...

When the ground under Seattle finally gives way, the disaster will not unfold as a single cinematic moment but as a chain reaction that reshapes the city’s geography, infrastructure and daily life.

Japan is learning what life is life under a megaquake watch. NPR's Rob Schmitz talks to Richard Allen, director of the Berkeley Seismology Lab, about what it means.
