The Yellowstone Caldera formed during an eruption of Yellowstone's supervolcano about 640,000 years ago. The eruption was far larger than any in human history, about 1,000 times larger than the 1980 eruption of Mount St. Helens. This event drain massive amounts of magma from the magma chamber beneath what is now Yellowstone, causing the land to collapse into the space left behind.

∙ 13y agoVolcanoes existed on the earth before we did. They helped build the planet. There is a very good chance, seeing as Yellowstone is a super volcano, that it's been here almost as long as the earth has but, there is also the chance it has been forming over millions and millons of years increasing in size (and still doing so) due to tectonic movement. No one can be to sure.It's like asking 'where does space end?'...no one can know for certain, only guess.
Hope this helps.
