There she is

hey is Seattle going to get wiped off the map by the tsunami that follows the big one or is that just Portland?

Just Seattle.

Portland’s 100 miles inland and in a way so is Seattle, but it’s on the Puget Sound.

This is not my understanding. Tsunamis can\u2019t make hard right turns, so there might be some water level rise and the boardwalk might eat it, but most of Seattle is not a tsunami hazard. Our real concern is all the landslides and soil liquefaction from a major earthquake. A lot of Seattle is on top of what\u2019s basically a mud flat and it will become very unstable when the shaking starts.

Red area = fucked

Yellow area = also fucked, but for other non-tsunami reasons

\n

The narrowness of the Columbia’s path through the Coast Range means a tsunami might make the river surge all the way back to Portland but no, our main concern in an earthquake is all the structures built before we realized Cascadian mega-quakes were a thing \u2013 including the bridges across the river dividing the city \u2013 collapsing. The Oregon coast, though, is gonna get scoured.
