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

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 ...

An unprecedented observation of a major geological process is currently taking place off the North American coast. For the first time, a scientific team has documented the progressive fragmentation of ...

The next great earthquake isn't the only threat to the Pacific Northwest. A powerful earthquake, combined with rising sea levels, could significantly increase flood risks in the Pacific Northwest, ...

Even long-lived subduction zones eventually die, and scientists believe they are witnessing the slow death of one in the northern end of the Cascadia subduction zone. A new study using seismic data ...

EUGENE, Ore. (NBC) -- 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 ...

A study looking at a small region in Japan has shown that the properties of fault zone rocks really matter for the generation of earthquakes. Earthquakes occur along fault lines between continental ...

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.
