Nevados Ojos del Salado is the world's highest active volcano. It is located on the Chile/Argentina border, about 20 km south of the road that crosses Argentina-CHile border at Paso de San Francisco.
The mountain has very dry conditions with snow only remaining on the peak during winter. The volcano contains two summit peaks of the same height.
A large explosive eruption took pleace about 1000-1500 years ago and produced pyroclastic flows.
Ojos del Salado is still active and has fumarolic activity at present, but there are no confirmed historical eruptions of Ojos del Salado. A report of minor gas-and-ash emission in 1993 could not be confirmed. The volcano currently shows fumarolic activity.

Background

from Smithsonian / GVP volcano information:
The summit complex, which is elongated in a NE-SW direction and overlies a largely buried caldera, contains numerous craters, pyroclastic cones and andesitic-to-rhyolitic lava domes and has been the source of Holocene lava flows. A major rhyodacitic explosive eruption took place about 1000-1500 years ago, producing pumiceous pyroclastic flows. The most recent eruptive activity of Ojos del Salado appears to have originated along a NNE-trending rift along the summit complex. It involved formation of a thick, viscous lava flow and at least a dozen small cones, lava domes, and explosion craters. No confirmed historical eruptions of Ojos del Salado have been recorded, but the volcano has displayed persistent fumarolic activity, and there was an unconfirmed report of minor gas-and-ash emission in 1993.

On top of the world... Our team member Ulla Lohmann is happy to have reached the world's highest volcano with almost 7000 m.
Ojos del Salado at 6893 m is the highest volcano of the world, the highest mountain of Chile and the second highest mountain in the world outside the Himalaya. The climb success rate is about 25%, and climbers can face extreme conditions at the top, wind gusts of up to 200 km/h and temperatures down to -30 deg C are nothing unusual here.
The volcano is located in the highest desert of the world, the Puna de Atacama, where still many remnants of the Incas can be found. They constructed offering platforms for sacrifice rituals (incl. human sacrifices) at an altitude of 6739 m!  (Photo: Basti Hoffmann)
