Considered five hundred times larger than a typical volcano, a supervolcano is classed as more than 500 cubic kilometres of erupted magma volume.

Supervolcanoes take just hundreds of years to grow

The largest volcanoes on Earth may take as little as a few hundred years to form and erupt, a new study has revealed.
