A subduction zone is created where two plates converge, with one sinking into the mantle. Dynamics along the plate interface create earthquakes, magma generated above the sinking slab leads to ...

A megasplay fault branches upward from the subduction zone, and in the event of "The Big One," would raise the seafloor, displacing a massive amount of water closer to the coast.

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.

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 ...

It’s the 323rd anniversary of the last Cascadia Subduction Zone earthquake.We spend a fair amount of time thinking about the ‘Big One’ (and the ‘Really Big One’) in the Pacific Northwest.

Subduction zone splay faults compound hazards of great earthquakes Date: May 20, 2024 Source: Virginia Tech Summary: Groundbreaking research has provided new insight into the tectonic plate shifts ...

A major earthquake along the Cascadia Subduction Zone could cause coastal land from to sink permanently, dramatically increasing the risk of flooding, according to a new study.

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 ...
