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.
"...no use in worrying about things you can't do anything about."
ReplyDeleteWise advice, however thinking about the possibility long enough to come up with a contingency plan so you're prepared is also wise.
You might already have a plan for a different scenario that would cover this too.
