Vigorous fumarolic activity occurs near the summit of Ollagüe volcano, and sulfur deposits have formed. Intensified fumarolic activity was reported in 1854, 1888, 1889, and 1960.

Steam pours from vigorous fumaroles near the summit of Volcán Ollagüe. This massive 5868-m-high stratovolcano is capped by a large dacitic lava dome. Collapse of the volcano produced a massive Pleistocene debris-avalanche deposit that extends to the west. Active sulfur mines on the upper western and southern flanks are reached by a road that climbs to about 5500 m elevation. Only increased fumarolic activity has been recorded at Ollagüe during historical time.
