Outrunning a volcano is good fodder for an action scene in a movie (or mediocre fodder if we're talking Volcano or Dante's Peak), but the reality of it is a little different. But only slightly! Research published this week in seems to indicate that racing away from a killer volcano might actually be doable...if you were in the right place, that is.
At ground zero, you'd be fried by a sudden eruption. But analysis of the Peach Springs Tuft in Arizona shows a different picture, . That 18-million-year-old eruption was huge, with a main impact site of 13.6 miles, and thick deposits of debris in a 105 mile area. The main eruption site would probably vaporize or severely burn you. Sorry. But at about 93 miles out, people in the area could have up to 10 hours to get out, assuming no accidents or traffic jams.
So if you plan to move to Wyoming but are scared of the supervolcano suddenly exploding, your best bet is about 100 miles out from the Yellowstone site. Otherwise, your chances of survival go way, way down. Wired , however, that this study focused on the Tuft eruption, and that it may not work in every case. So...maybe choose 200 miles.
