... A supervolcano is a volcano that erupts with a massive volume of material, much more than from a normal volcano – at least 1000km3 of magma. To give you some idea of the great volume, the big eruption of Mount St Helens in the USA in 1980 produced 1km3. A super-volcanic eruption alters the landscape ...

Lastarria

Lastarria, also known as Azufre, is a stratovolcano along the border of Argentina (border of the Catamarca and Salta provinces) and Chile (Antofagasta region). The volcano is part of the Lazufre volcanic system and is noted for the presence of molten sulfur lava flows as well as a debris avalanche. There is no recorded activity in historical times, but ground inflation has been observed.
