That Elblag Canal video was amazing, Brett.

Meh...no matter where you go, I think, there are the low probability but with high negative consequence destructive natural events that might occur.
Here in western Oregon for example, tornados are rare indeed...but the likelihood of a Richter scale 9+ quake and probable subsequent tsunami within the next 20 years, historically speaking, is very high...long overdue, many experts say.
On Big Island, aka Hawaii, tornados are even rarer than here...but lava flows are a real risk on a good portion of the southeastern part of the island day in and day out.
No free lunch.
