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.
