Uturuncu volcanoUturuncu volcano is the highest peak in SW Bolivia and located SE of Quetana. The stratovolcano consists dominantly of andesitic to dacitic lava flows and some are probably less than 10,000 years old. At present, there are 2 solfatara fields near the summit.
Large-scale ground deformation, a bulge growing one inch per year, has been detected since May 1992 as well as increased seismic activity. This indicates that magma is still moving beneath the volcano.
