Terry,

>I saw a recent TV series that has covered all the cataclysms and it was still on the agenda. First heard of it a few years ago.

I think I saw that same series. Megadisasters, maybe? Dunno who would show it in the UK but it was a History Channel show here I believe.

>>As to to the mega-caldera in Yellowstone, there would have to be a lot of signs a long time before that happened and there are few, if any, signs that anything is happening there.

>But even if you get the signs there's NOWHERE ANY OF US can run! :-)

True. But look at the bright side - the amount of ash residue pumped into the atmosphere would put the kibbosh on global warming! A win-win situation (lol).

Seriously, I don't worry about any of this. Our forefathers slogged through Krakatoa, the New Madrid quake, the Tungeska strike, and what all. Whatever happens, we'll manage.
