Cascadia: The Earthquake that will Destroy Westcoast America
Geographics・2 minutes read
The Cascadia Megathrust Fault on America's west coast could trigger one of the most massive earthquakes in history, leading to widespread devastation, building collapses, fires, landslides, dam failures, and chemical spills, followed by a tsunami inundating coastal communities and covering hundreds of thousands of square miles. The potential for a magnitude 9.2 earthquake along the Cascadia fault would have catastrophic consequences, with experts warning of significant destruction, including impacts on buildings, schools, hospitals, bridges, fires, gas leaks, landslides, dam failures, and chemical spills, as well as a tsunami reaching heights of 20-100ft and affecting millions of people, with estimates of 13,000 deaths, 27,000 injuries, and up to a million people losing homes.
