Juan de Fuca Plate

And scientists believe it strikes here every 200 years, which means we are long overdue for one.

They are estimating that a 9.0 to 12.0 earthquake will hit and that it will cause the Juan de Fuca plates to slip, triggering a 1,000-foot tsunami to strike our coastline here in Washington State, Oregon, and California.

The Cascadia megaquake will likely be the biggest disaster to ever hit the United States.

But new research now shows that it could be way worse than we once thought.
