Olca-Paruma volcano is a group of 3 stratovolcanoes forming a 15-km-long E-W ridge along the northern Chile border with Bolivia. There are 3 stratovolcanoes in the complex: Volcán Olca, Cerro Michincha, and Volcán Paruma.
The only known historical activity from the Olca-Paruma complex was a flank eruption between 1865 and 1867 from an excentric flank vent. Since around 1990, volcán Paruma has displayed persistent fumarolic activity.

Introduction:

The complex contains prominent andesitic-dacitic lava flows extending 5 km north from the active summit crater of Volcán Olca as well as lava flows to the north and west originating from vents farther to the west. Volcán Paruma has erupted fresh-looking lava flows of unknown but likely young age, one of which extends 7 km to the SE.
