What is unique about the West Mata submarine volcano?
... The West Mata volcano produces pillow lavas and both pyroclastic and phreatic events occuring at its two vents, named Prometheus and Hades. Boninite is a primitive andesite composed of mafic extrusive rock that is derived from metasomatised mantle melting and likely fractional crystallization. It co ...

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.
