On the picky side of complaining about lack of copy edits and grammar checking; Dr. Smith has been studying Yellowstone’s earthquakes and it’s Super Volcanos for almost sixty years. How many volcanoS?
This is a link to a quite good Yellowstone Volcano eruption movie from BBC (2005). Not a good event, Obama would probably leave for Hawaii!
