Olca

The Olca volcano rises to an elevation of 5,407 meters within a 15-kilometer mountain ridge that includes Cerro Minchincha and Paruma volcanoes.

The last recorded volcanic activity occurred between 1865 and 1867, with subsequent observations of fumarolic emissions in November 1989 and March 1990.

The mountain holds significance among indigenous Andean communities who maintain traditional connections to the volcanic landscapes of northern Chile.

Access to the volcano requires preparation for extreme altitude conditions and obtaining necessary permits for geological exploration or scientific research.

The summit features a persistent fumarolic field covering 0.1 square kilometers, emitting a mixture of high-temperature gases and hydrothermal fluids.
