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.

During an earthquake scenario with the highest level of subsidence, or land sink, the area at risk of flooding would expand by 116 square miles. Among the areas at risk after a megaquake along the ...
