The Uturuncu volcano is located in southwest Bolivia near the Argentine border. The closest place is Quetena Chico . The main peak has a height of 6008 meters, the secondary peak is 5930 meters high. A road leads up to around 600 meters in altitude to the summit, the ascent does not present any technical difficulties. Due to its unfavorable location in the remote Cordillera de Lípez , the Uturuncu is rarely climbed despite its easy climbability.

geology

The Uturuncu is a dormant stratovolcano, which is shaped by Dazite lava. The last eruption was 271,000 years ago. Isolated fumaroles and sulfur rocks clearly indicate that volcanic activity is still present. The latest findings suggest that the Uturuncu is a candidate for a strong eruption (6 or higher on the volcanic explosion index ) up to the supervolcano , which increased in activity towards the end of the twentieth century. Radar images show that the area around the volcano rises continuously within a radius of tens of kilometers, the rates of elevation in the vicinity of the volcano reach one to two centimeters per year. In addition, increasingly smaller earthquakes are being registered, which also indicate the penetration of magma into a reservoir at a depth of 15 to 20 kilometers.
