Hotspots are deep-seated sources of heat and magma that extend from depths as deep as the core-mantle boundary and generally stay fixed relative to plate motion – the plate move across the hotspots, but the hotspot doesn’t move. Volcanoes are left behind in tracks that show us the direction and spee ...

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.
