New evidence suggests current estimates about tsunami size and how quickly waves make it to shore may be too high and too ...

N ewly-released research led by the University of Washington (UW) showed that a feature scientists hypothesized was present along the Cascadia Subduction Zone is missing in places.

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 ...

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 properties of the subduction zone offshore Chile change from south to north, and before now a lot of the focus has been on the role of features on the oceanic plate," said Stephen Hicks, lead ...
