Scientists investigate the Cascadia Subduction Zone off the Pacific Northwest, and the potential for a catastrophic tsunami.

The tsunami wave from an anticipated earthquake off the West Coast could reach 100 feet and permanently flood parts of the coast.

Just off the coast of the Pacific Northwest is the Cascadia Subduction Zone, a complex collection of earthquake faults created... Read Story ...

A so-called "doomsday tsunami" is likely to hit the United States in the near future, but scientists now say there is a possibility that it could happen sooner than previously thought.

It is named after the Cascadia Subduction Zone — a 600-mile-long fault just off the coast that runs from Northern California to British Columbia.

Scientists are sounding the alarm on a 'sleeping giant' off the coast of California, warning it could sink land in several states in just minutes.

There has not been a major earthquake in what is known as the Cascadia subduction zone since about 9 p.m. on Jan. 26, 1700, long before Europeans first landed on Vancouver Island.

A major West Coast earthquake along the Cascadia subduction zone could have an unexpected and destructive side-effect for shoreside communities throughout the region.. Research recently published in ...

Chile – As the only segment of the Chile-Peru Subduction Zone not to have ruptured within the last 100 years, the north Chile segment is now considered to be a region at high risk from an ...

Most of the quakes happen near the Cascadia subduction zone, an area where the Juan de Fuca and North American tectonic plates converge, stretching from Vancouver Island to northern California.

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 largest earthquakes rupturing along the whole subduction zone may have magnitudes up to 8.6. A mega-earthquake in this region would most likely be a market-moving event.5.
