    Volcanoes that have produced explosive VEI-8 eruptions, often called supervolcanoes in the media. Such eruptions release a tephra volume of at least 1,000 km 3 (240 cu mi) with annihilating long-term effects on the surrounding area and devastating short-term effects on global climate, leaving profound effects on the climate for years to come.
