The largest (super) eruption at Yellowstone (2.1 million years ago) had a volume of 2,450 cubic kilometers. Like many other caldera-forming volcanoes, most of Yellowstone’s many eruptions have been smaller than VEI 8 supereruptions, so it is confusing to categorize Yellowstone as a “supervolcano.”

Will Yellowstone erupt 2020?
Yellowstone is not overdue for an eruption. … The rhyolite magma chamber beneath Yellowstone is only 5-15% molten (the rest is solidified but still hot), so it is unclear if there is even enough magma beneath the caldera to feed an eruption. If Yellowstone does erupt again, it need not be a large eruption.
Will Yellowstone kill us all?
1. Yes, it will! But the next eruption is likely to be pretty small, just a bit of lava extruding with maybe minor amounts of ash. … If the next enormous eruption happens in our lifetimes, there will of course be death and destruction, but not enough to destroy the United States, or even just the American West.

Which volcano will destroy the world?
The Yellowstone supervolcano — an 8 out of 8 on the Volcanic Explosivity Index — has erupted three times over the past 2.1 million years, most recently 640,000 years ago. A Yellowstone eruption would be like nothing humanity has ever experienced.
Who would die if Yellowstone erupted?
Should the supervolcano lurking beneath Yellowstone National Park ever erupt, it could spell calamity for much of the USA. Deadly ash would spew for thousands of miles across the country, destroying buildings, killing crops, and affecting key infrastructure. Fortunately the chance of this occurring is very low.
Which supervolcano is most likely to erupt?
