Te natury of Superwulkany

A superwulkan is definite nod t by it shape but by thee sheer volume of material it can eject during an eruption. The moldold is an erupstion that expels more than 1,000 cubic kilometers of magma - routly 240 cubic miles. To put that into perspectiva, the 1980 Mount St. Helens erphystion revoased about 0.2 cubic miles.
