description Ollague summit fumaroles Overview
The Ollague summit fumaroles are volcanic gas vents near the summit of Ollague, a stratovolcano on the border between Chile and Bolivia in the central Andes. The vents occur around a summit lava dome and release a plume that can be visible from considerable distances, providing clear evidence of continuing hydrothermal activity. They are of interest to volcanologists and geologists monitoring gas emissions, thermal activity, and the behavior of high-altitude Andean volcanoes.

Is Ollague a volcano or a geothermal field?
Ollague is a stratovolcano, and its summit fumaroles are volcanic gas vents associated with that volcano. The vents occur around a summit lava dome.
Why are summit fumaroles scientifically important?
Fumaroles provide evidence of gases escaping from heat below a volcanic summit. At Ollague, their location near the lava dome helps show the continuing hydrothermal and volcanic activity of the mountain.
