Part 1 of 5 · freeIntroduction
An eruption that throws out more than 1,000 km³ of ash, rock and gas, enough to fill 400 million Olympic swimming pools: that is the scale of a supervolcano. It does not necessarily look like a cone-shaped mountain. Its giant eruptions leave behind a caldera instead, a huge basin formed when the ground collapses after a large amount of magma escapes from below.
The danger would not stop at the foot of the volcano. Ash could cover vast areas. Gases would rise high into the atmosphere. Some effects would be felt thousands of kilometers away, others all around the planet. So what would happen if a supervolcano really woke up?
