There is simply no way to predict which one of the super volcanoes will go and when they will do it, and any survival will be determined by chance. One cannot plan for this type of crisis. It's too random and too global. If it's Yellowstone, we are all toast anyway. We are too close.

Krakatoa's (SP) last eruption put the entire globe in a depressed temperature state for years and the ash blocked what little solar radiation could get through. Crops all around the globe failed, starvation was moderately systemic everywhere. That was just a regular volcano, albeit huge.
^this pretty much covers it. We'd be over with.
