The Cascadia Subduction Zone is a sleeping monster lurking just off the Northwest coast of the United States. It extends 600 miles between Northern California and Vancouver B.C. and experiences a massive megathrust earthquake every 250 years on average. The last one happened 321 years ago and scientists say there is a 30% chance we’ll see another in the next 50 years.
