Butte in Supervolcano
When Kelly Birnbaum was rescued by helicopter from Yellowstone National Park just before the supervolcano erupted, the pilot flew to Bert Mooney Airport in Butte, Montana which was at the limits of his fuel load. Just after landing, the volcano erupted shooting a cloud of ash 100,000 feet into the air. It was clearly visible in Butte even though the city was a couple of hundred miles away. The shock wave of the eruption arrived a few minutes later in the form of a massive earthquake. The quake knocked down a number of buildings in the city and broke windows of most that remained standing.
