Given an estimate of how big the magma volume is how long does it take for a Super Volcano Eruption (VEI 9+) to happen. There's a mystical reference to 150 days of hell with multiple (I use six and they're symmetrical so it's easier for me) vents cutting open the edge of what will be the caldara. I show how this results in a yellowstone class eruption, but not in the US.
