Seasteading! What about tsunamis?

Tsunamis are luckily harmless on the deep sea. They’re only destructive when they reach land.

In 2004, when a tsunami struck Thailand, scuba divers a quarter mile from shore didn’t even notice as it passed through them and demolished the hotel they’d eaten breakfast in that morning.

A tsunami wave is often more than a hundred miles long. Passengers on boats can’t detect a tsunami because it slowly raises the elevation of the boat a few feet over the course of twenty or thirty minutes. It’s not until the virtually invisible wave strikes a continental shelf that it begins to tumble and roll.

Buildings fixed to the edge of continents are sitting ducks in a tsunami. Some MIT scientists argue that nuclear power plants should float at sea to protect against tsunamis.

Someday, we expect people living on seasteads to ask land people, “But what about tornadoes, earthquakes, and tsunamis? Isn’t it dangerous to live on land?”
