ORIGINAL: jlf1961 Sense the maximum ash fall where I live would be about a centimeter or less, with negligible health impact, I aint too concerned. As far as climate change after such an eruption, I am too far south for anything more than a cooling of climate rather than year round snow. The depth of ashfall in Texas would be dependent on the precise location of the jet stream and prevailing winds and air masses at the time of the eruption. Anything within 1000 miles of the caldera can expect significant accumulations of ash. As to the eruption winter, you would expect it to last, worldwide, for 2 to 5 years. Krakatoa, which was at least an order of magnitude smaller, resulted in a ruined growing season across the enitre planet. It might not snow but it would make growing crops impossible, little to no sunlight, for several years. This is why preppers make me laugh. Anything severe enough to take out the human civilization long term is not survivable by a few hardy souls living on a years supply of freeze dried food. At minimum you'd want 5 years of food for your group plus the same amount of livestock feed (and the actual livestock), basic farming equipment and sufficient non hybrid seeds to plant at least the first 2 to 3 years of crops. So basically tons of supplies per person.
