Hello Don in Colorado,

If they do-- it will be unintentional--but of course that won't make you feel any better.  I am no geologist, but setting off all those nukes might possibly wreck the surrounding water tables or aquifers with earthquakes and ground settling.  Maybe jumpstart a volcano too?  Having plenty of local oil, but suddenly having no nearby water seems like a bad tradeoff to me.

I kind of like the volcano idea, Bob.

I built my house out of concrete-reinforced rastra block. I think it could survive the concussion of nuclear blasts on the other side of the Grand Mesa, but I still need uncontaminated water, and too much dust from nuclear fallout might really make my passive solar windows inoperative.

Maybe we should all move to Tahiti ...
