Photo Gallery


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.
