Everyone knows Yellowstone, located in the northwest area of Wyoming, for bison, geysers, Yogi Bear and the beautiful natural formations, but one of the most fascinating aspects of this place is hidden under the ground: the Yellowstone caldera (volcanic crater formed after the collapse of an empty magma chamber) is one of the few supervolcanoes on the earth, formed after the Lava Creek eruption, approximately 630,000 years ago, and now located in one of the so-called earth’s crust hot spots, where the magma goes through the earth’s mantle and approaches the surface. The caldera measures approximately 50 kilometers long and 75 kilometers wide.
It is supposed that the destructive potential of the Yellowstone caldera is thousands – maybe millions – of times higher than the atomic bombs dropped on Hiroshima and Nagasaki during World War II.
