Well, if the supervolcano that pretty much is Yellowstone National Park goes up, then most of us will not survive it or the subsequent nuclear winter.
@forner: North American Super Volcanoes1 - Yellowstone National Park sits on a subterranean chamber of molten rock and gasses so vast that it is arguably one of the largest active volcanoes in the world. A magma chamber not far below the surface fuels all the volcanic attractions that Yellowstone is famous for. The last major eruption at Yellowstone, some 640,000 years ago, ejected 8,000 times the ash and lava of Mount St. Helens.2 - Long Valley caldera, in east-central California. The 200-square-mile caldera is just south of Mono Lake, near the Nevada state line. The biggest eruption from Long Valley was 760,000 years ago, which unleashed 2,000 to 3,000 times as much lava and ash as Mount St. Helens, after which the caldera floor dropped about a MILE, according to the U.S. Geological Survey. Some of the ash reached as far east as Nebraska.3 - The 175-square-mile Valles caldera forms a large pock in the middle of northern New Mexico, west of Santa Fe. It last exploded 1.2 million and 1.6 million years ago, piling up 150 cubic miles of rock and blasting ash as far away as Iowa.
