Toba catastrophe theory Supervolcano A supervolcano is a large volcano that has had an eruption of magnitude , which is the largest value on the Volcanic Explosivity Index VEI This means the volume of deposits for that eruption is greater than , cubic kilometers cubic miles. Indonesia s Lake Toba Supervolcano Threatens Global Indonesia s Toba supervolcano the site of the world s largest volcanic lake in Sumatra came alive late last month, producing hot steam and foul smelling gas The recent activity has raised fears of a major eruption after , years. Yellowstone, Toba and Taupo Supervolcano list and facts Supervolcanoes are loosely defined as volcanoes that can eject than ,km of material during an eruption around , times bigger than a normal volcano. Supervolcanoes discovered in Utah by BYU geologists Brigham Young University geologists found evidence of some of the largest volcanic eruptions in earth s history right in their own backyard These supervolcanoes aren t active today, but million years ago than , cubic kilometers of magma erupted during a Supervolcano Not to Blame for Humanity s Near Extinction About , years ago, the Toba Supervolcano erupted in what is now Indonesia After the eruption, the ground collapsed and left behind a depression called a caldera, which is not filled by Lake Supervolcanoes Around the World Owlcation Mar , Lake Taupo is one of the world s great supervolcanoes The most recent eruption was , years ago, when a VEI eruption ejected cubic miles of volcanic material into the air THe event is known as the Oruanui eruption.
