An explanation of the Cascadia Subduction Zone, which runs roughly 31 miles offshore, approximately 683 miles from northern California up through Vancouver Island off the coast of British Columbia. This fault zone has generated massive earthquakes over and over again throughout geologic time. It generates a monster earthquake about every 500 years –and it's due to return at any time. It could happen 200 years from now, or it could be tonight.
