YVO gets a lot of questions about whether Yellowstone, or another caldera system, will end all life on Earth.

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.
Can Yellowstone wipe out America?
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.

What will happen if Mt Rainier erupts?

Can a super volcano cause an ice age?
