The Yellowstone Supervolcano

This warning was posted by geologist Christopher C. Sanders on January 1, 2009: "I am advising all State officials around Yellowstone National Park for a potential State of Emergency. In the last week over 300 earthquakes have been observed by the USGS. We have a 3D view on the movement of magma rising underground. We have all of the pre warning signs of a major eruption from a super volcano. - I want everyone to leave Yellowstone National Park and for 200 miles around the volcano caldera."

It looks like he was off by some unknown interval. The supervolcano has yet to blow. If it were to blow, from what I saw on the island of Thira (a/k/a Santorini) in Greece, 200 miles might be just enough distance to survive. Read the article on Sangtorini's supervolcano here, on All This Is That.
