Scientists are warning about a terrifying “mega tsunami” that could strike the US West Coast within minutes. Triggered by the Cascadia Subduction Zone, one of North America’s most dangerous fault lines, the wave could reach nearly 1,000 feet.

“If it ruptures, the tsunami will be immediate and devastating,” said lead researcher Tina Dura. Cities like Seattle, Portland, and coastal towns in California could be swallowed within minutes.
Experts say there is a 15% chance of a magnitude 8 or stronger earthquake in the next 50 years. By 2100, scientists believe such a disaster is almost certain. Rising sea levels would only make the wave deadlier. “The land will sink and remain lower for decades,” warned researchers.

The last massive quake struck in 1700, creating a tsunami that wiped out entire villages. Now, scientists are urging urgent planning to reduce risk. The question remains—are we truly prepared for nature’s most destructive force?
