The three caldera-forming eruptions at caldera (2.1 million years ago, 1.3 million years ago, and 640,000 years ago), were respectively about 2,500, 700, and 1,000 times larger than the caldera in the state of Washington.
Is Yellowstone the largest volcano in the world?
Yellowstone National Park, the world’s first and arguably most famous national park, is home to one of the planet’s largest and potentially most destructive volcanoes. The 50- by 70-kilometer Yellowstone caldera complex is so massive that it can really be appreciated only from the air.

the Yellowstone supervolcano
Yellowstone National Park
In the previous 2.1 million years, the Yellowstone supervolcano, which scored an 8 on the Volcanic Explosivity Index, has erupted three times, most recently 640,000 years ago. An eruption at Yellowstone would be beyond anything the human race has ever known.
How far would Yellowstone reach if it exploded?
The eruption could be expected to kill as many as 90,000 people immediately and spread a 10-foot (3-meter) layer of molten ash as far as 1,000 miles (1,609 kilometers) from the park.

How many Super volcanoes are there on Earth?
There are about 12 supervolcanoes on Earth — each one at least seven times larger than Mount Tambora, which had the biggest eruption in recorded history. If all of these supervolcanoes erupted at once, they’d likely pour thousands of tons of volcanic ash and toxic gases into the atmosphere.
