Oehler Structures - how much abuse can they take?

  Question for Mike - I am curious to know just how much abuse the houses you design can take. Your website says they can stand :
"-Hurricane
-Tornados
-Earthquakes
-Rampant Fire
-Atomic Fallout
-Mobs, gunfire, blasts, and similar results of social disintegration"
I assume you have been unable to test the last two. Have you actually subjected any to the other conditions? If not, it would be interesting to find out
