Supervolcanoes occur when magma in the mantle rises into the crust but is unable to break through it and pressure builds in a large and growing magma pool until the crust is unable to contain the pressure. This can occur at hotspots (for example, Yellowstone Caldera) or at subduction zones (for example, Toba).. Large-volume supervolcanic eruptions are also often associated with large igneous. The Island Park Caldera supereruption (2.1 million years ago), which produced the Huckleberry Ridge Tuff was the largest and produced 2,500 times as much ash as the 1980 Mount St. Helens eruption.
