well, the bobm at hiroshima also released radiation, which killed alot of people, so it's not as bas as you think.
Not as bad as you think?
Did you happen to notice the big fuss over the twin towers going down?
Now times that by a city of buildings, some bigger, some smaller, and all of them destroyed, then you tell me its not as bad as you think.
then multiply that by 90% of the united states and you get the super volcano we're talking about, not a big deal my ass.
90% of the US is a big deal. Hopefully it won't be happening in my lifetime, I've also heard of another natural disaster that involves a mega tsunami striking eastern US, but that's unrelated to the subject.
