What You Need to Know About a Supervolcano Eruption

Volcanic eruptions are graded on a scale, the Volcanic Explosivity Index, to compare which ones are really the biggest. We've seen some pretty big ones, but nothing above a VE7. For those, you have to go back millions of years. Kurzgesagt explains the what causes volcanic eruptions, how we measure them, and whether we should be worried about a supervolcano. Hint: a wise man once told me that there's no use in worrying about things you can't do anything about. Also, Volcanic Explosivity Index would be a great band name.
