Today, the Cascadia Subduction Zone remains eerily quiet. In other subduction zones, scientists often observe small earthquakes frequently, which makes the area easier to map, according to Carbotte.

Scientists warn if a 1,000-ft ‘mega-tsunami’ spurs from an active fault line it could wipe part of America off the map - Alaska, Hawaii and areas along the mainland West Coast would be at risk ...

While Cascadia hasn't produced a great earthquake since 1700, it's only a matter of time. Scientists can't predict earthquakes but they can get a better idea of risk by understanding the fault's ...

Sub-seafloor map of the Cascadia Subduction Zone, showing depth of the fault between the eastward-moving Juan de Fuca place and the North American plate. Yellow/orange indicates shallow depths ...

A 300-meter-high tsunami crashing into the US coast might sound like science fiction—but scientists say it's a very real threat. Backed by geological records and advanced AI models, researchers ...

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.

Megaquakes have occurred on the fault at least seven times in geological records dating back over 3,000 years. It is thought that such quakes, those with magnitudes over 8.0, occur there every 400 ...

This seep isn’t either of those. It’s linked to a fault line: Scientists first mistook the leak for a cold methane seep – there are at least 1,000 methane seeps in the region.

University of WashingtonThe Cascadia Subduction Zone (CSZ) is a massive fault line stretching from Vancouver Island to Northern California—and it’s the source of the vast majority of ...
