That's somewhat reassuring (there's thought to be a 12% chance of a Cascadia mega-quake and accompanying west coast tsunami in the next twenty years).

- rtkwe 11y agoYeah the main factor in how much will a large wave or tsunami affect a structure at sea is how deep is the water the object is in. Out in the deep ocean the surface swell is less than a meter and the wavelength is huge (200 km or so long) so the change is relatively gentle and gets subtler as you get deeper. It's really neat. https://en.wikipedia.org/wiki/Tsunami#Characteristics https://en.wikipedia.org/wiki/Tsunami#Characteristics
