Skarpi, I lived for many years on or near the New Madrid Earthquake Fault -- the one that rattled the US midwest a couple weeks ago. That was also tornado country. If I learned nothing else, I learned that you can be prepared for a disaster but if a tornado/hurricane/volcano/earthquake is going to happen there is nothing you can do about it except try to get out of the way.

Someday every place in the United States will have a disaster. Every place in the world will.

I don't think my giant cork will stop it if Yellowstone wants to blow up.
