well to be honest i believe that a supervolcano or two will go off in the next 100 years, could be tomorrow, who knows?
All I can tell you, is be prepared. You want to stock up on water and canned foods...but most importantly water. You want to be away from America
and Away from The Far East.
Many of us will survive if 1 super volcano goes off. If 2 of them go off then you can expect it to be cold for a long time.
So dress warm
