Olca-Paruma

Type
Stratovolcano
Elevation
5705m
Last eruption
Unknown
The Olca-Paruma volcanic complex, seen here from the west, forms a 15-km-long E-W ridge forming the border between Chile and Bolivia and is comprised of several stratovolcanoes with Holocene lava flows. Volcán Olca lies near the western end of the complex. It is flanked to the east by Volcán Paruma, which is immediately west of the higher pre-Holocene Cerro Paruma volcano, the conical peak in the background. Volcán Paruma has been the source of conspicuous fresh lava flows and has displayed persistent fumarolic activity in recent years.

From Wikipedia

Olca-Paruma is a volcanic complex in Chile. Lying on the border between Chile and Bolivia, it is formed by an east–west alignment of volcanoes. From west to east, these are Cerro Paruma, Volcan Paruma, Olca, and Mencheca or Michincha. Aside from the mines of Ujina, Rosario, and Quebrada Blanca, the area is sparsely populated.
