What is a Supervolcano?
A supervolcano is a volcanic eruption that is substantially larger than any volcano in historic times. This type of volcanic eruption occurs when magma in the Earth rises into the crust from a hotspot but is unable to break through the crust. A large, growing magma pool is built because of pressure until the crest is unable to contain this pressure. Throughout history, there have been only a handful of these eruptions which typically causes a long-lasting change to weather.
There have been many films and documentaries on supervolcanoes throughout the years. A two-part television docudrama titled Supervolcano, looked at the events that would take place if the Yellowstone supervolcano erupted. Computer-programming enacted the devastating events that would take place all over the world. It was stated in the docudrama that all of the United States would be covered with at least one centimeter of volcanic ash, which would cause mass destruction in the nearby vicinity, killing plants and wildlife all across the continent.
