Does anyone know how an eruption of a supervolcano, such as Yellowstone or the Bay of Naples, would effect the world? How big would the area destoried be? How big would the ash cloud be? How long would the volcanic winter last? How long would crop yields be low? Mostly I just need a timeline of the possible effects of a supervolcano eruption (and I am assuming that humanity lives).
