A supervolcano is defined as having the capacity to produce an eruption so big that it can eject around 240 cubic miles of volcanic material in the form of molten rock, hot gases, and ash.

That's roughly one thousand times more than the largest volcanic eruption ever recorded in modern human history. Supervolcanoes are formed when a momentous volume of super-heated magma rises from deep underground, but is unable to penetrate the Earth’s crust and creates a huge, high-pressure pool several miles beneath the surface.
