I remember reading that Seaside had a facility in town that would raise people above a tsunami so that it would pass under them. All they would have to do is get to that facility in town and not “run for the hills” ... :-) ...
I don’t know if that facility is completed now, or still to be completed.
It’s been a couple of years since I’ve been there and I recall that two stories was about the limit near the beach. I’d hope they have something now.
I believe that has been around for awhile now - a hotel and/or casino I think. The thing is built on piles, with the lower level walls designed to break easily when the tsunami comes. (The walls break, the vertical columns support the upper floors.) Vertical evacuation. yeah - they don’t have much time when the big one hits. And it will. Some day.
