. . where the Pacific Ocean is now. The Pacific Plate shoved the whole thing down under the North American Plate - except a fragment along the Pacific Northwest - which is still being shoved under.

As that former continent is shoved under, it causes the land to bulge up to the east. When it finally releases, the land slides west and drops. This action causes a very major tsunami, affecting the coast from Vancouver Island to the northern border of California.

Geologists have determined these slippages happen on average every 300 years. It is now 321 years since the last one. The tsunami could hit this afternoon, or 150 years from now, we do not know. What we do know is that it will happen.

Geologists expect that pretty much everything west of the I5 will be wiped.
