Definition:)

What is a supervolcano?
A supervolcano is any volcano capable of producing a volcanic eruption with an ejection volume greater than 250 cu miles. This is thousands of times larger than normal volcanic eruptions. Supervolcanoes are on a much bigger scale than other volcanoes, and if one of the more mammoth super volcanoes were to erupt it might change the world as we know it
