Uturuncu
Mountain Bolivian stratovolcano notable for geothermal unrest studies
High-altitude volcano in southwestern Bolivia’s Potosí region; visited by trekkers and scientists for its c. 6,000‑metre summit, puna landscapes, nearby salt flats and evidence of ongoing geothermal uplift.
Uturuncu is a high-altitude volcanic massif in southwestern Bolivia rising to about 6,008 metres above sea level. It forms part of the Central Volcanic Zone of the Andes and stands on the Altiplano.
There are no recorded historical eruptions; the volcano is notable to researchers for ongoing ground uplift and geothermal activity detected by remote sensing and geophysical studies in recent decades. Scientific projects study Uturuncu to understand magmatic processes beneath high-plateau volcanoes.
The volcano formed during the Quaternary and consists of volcanic deposits typical of Andean stratovolcanoes; modern interest is primarily geological and geophysical rather than mountaineering infrastructure.
Located in Potosí Department on the Bolivian Altiplano, Uturuncu lies in a remote highland area that is reached from regional towns and research stations in southwestern Bolivia.
- Elevation: Summit altitude about 6,008 metres above sea level.
- Scientific interest: Target of scientific study due to recent decades of satellite-detected ground uplift and geothermal signatures beneath the massif.
