description Ollagüe fumaroles Overview
The Ollague fumaroles are volcanic gas vents associated with Ollague, a stratovolcano on the border between Chile and Bolivia in the central Andes. They occur at high altitude in an arid volcanic landscape and release heated gases from the volcano's hydrothermal system, producing visible vapor and sulfur-bearing deposits around active areas. The site is relevant to volcanology because fumarolic activity provides evidence of persistent heat and fluid circulation beneath the volcano.
