Turns out the Yellowstone supervolcano is 2.5 times larger than previously thought (http://www.bbc.co.uk/news/science-environment-25312674). mizkit and I agree this calls for a new Syfy movie, in the tradition of Supervolcano, Super Eruption, etc. All we need is to file the serial numbers off an old script, throw in a handful of sharks a la Sharknado, and we're good to go. We could probably write the whole thing in an afternoon.
This post started as a joke, but now I'm halfway convinced that we could do this, and get Syfy to buy the movie rights.
