But despite their destructive capabilities, They can also make way for life renewed. Around 20 supervolcanoes scattered across the planet. They are usually characterized as large depressions in the ground, called calderas, located above multiple openings in the Earth's crust. In terms of eruptions, supervolcanoes explode at a magnitude of eight, the highest and most violemt classification on the Volcanic Explosivity Index (VEI). Supervolcanoes undergo a life cycle of three major stages: a surge of trapped magma, a supereruption and a resurgence 1.
