I think more people die in car related deaths than Tsunamis. You are focusing on the unlikely and then spending tons of time pondering it. Its unhealthy and leads to poor mental health.

Tsunamis nowadays come from earth quakes, potential tsunamis from underwater slides, despite it’s low probability would kill millions in coastal areas, but yeah, maybe I’m paranoid because I’ve read The Swarm by Frank Schätzing,
I mean still it’s a widely accepted and real concept
