What do you know about the Yellowstone supervolcano?

2. Dying from silica ash and/or superheated poisonous gas is not on my list

of least horrible ways to check out. People at the caldera or within a few miles might be able to hope for quick incineration but the rest of us would check out slowly and in agony. If we have respirators, we'd still have to watch our dogs and cats suffocate slowly.

If we were in an area of the country that escaped the ash fall, we could look forward to famine as the entire grain belt and most of the meat producing areas were wiped out under a thick blanket of ash.

The North American Plate is moving to the southwest. If there is a warning of a new supereruption, it will come from northeast of the present caldera. As of now, the plume has a kink in it, delivering magma under the caldera to cool slowly as it raises the floor. At some point, that hot spot will experience an updraft, an increased quantity of superheated magma, and the kink will be bypassed for a direct route, fracturing and them blowing apart the land and mountains directly over it.

Let's hope we're all long gone by the time it happens.
