The Devastating Effects of a Supervolcano Eruption

Way back in 1816, Europe and North America suffered heavy rains, odd-colored snow, famines, fogs and bitter cold during the summer. It wasn't the apocalypse though—it was the result of a supervolcano eruption.


In fact, the effects of Mount Tambora in Indonesia were felt over 1,000 miles aways and endured for at least a year after it erupted. This video explains the very real and colossal consequences of a supervolcano—both near and far. [TED-Ed]

Mount Tambora is a stratovolcano, not a supervolcano, and the 1815 eruption, although massive, wasn't a supervolcano eruption. Ejecting about 160 cubic kilometers of material, It is classified as a VEI-7, an order of magnitude smaller than 1000+ cubic kilometers ejected from a supervolcano (VEI-8) eruption. The most recent supervolcano eruption was the Oruanui eruption of Taupo in New Zealand, about 26,000 years ago.
