Quetena Volcano

關於

Quetena is a fissure-vent volcano in southwest Bolivia, located in the Sur Lípez Province of the Potosí Department, near the border with Chile. It rises to 5,730 metres (18,800 ft) above sea level with a topographic prominence of 998 metres (3,274 ft), and lies in the Cordillera de Lípez within the Central Volcanic Zone of the Andes. Quetena is the tallest fissure-vent volcano in the world.

The volcano lies within the Eduardo Avaroa Andean Fauna National Reserve, and the villages of Quetena Grande and Quetena Chico lie at its foot. Quetena is a comparatively easy high-altitude ascent typically approached from Quetena Chico. It is one of several minor volcanic centers northeast of Uturuncu, the region's largest stratovolcano.

A 1977 survey attributed fissure-fed lava flows at Quetena to the Holocene, but a later evaluation concluded that the volcano's activity likely occurred in the Pleistocene or earlier.
