Yellowstone National Park sits on a supervolcano.

Yellowstone boasts hydrothermal features fuelled by the supervolcano.

There is evidence of a massive depression called a caldera, which suggests that the last eruption of the volcano happened 640,000 years ago.

When Yellowstone's supervolcano next erupts it will produce an explosion with the power of 1000 atomic bombs.
