Sairecabur

Sairecabur is a volcano located on the frontier between Bolivia and Chile. It is part of the Andean Central Volcanic Zone. Sairecabur proper is 5,971 metres high; other mountains in the range are 5,722 metres high Curiquinca, 5,819 metres high Escalante and 5,748 metres high Cerro Colorado, all of which have erupted a number of lava flows. Also in close proximity to Sairecabur lie the volcanic centres Licancabur, Putana and Juriques.

Sairecabur proper is accompanied by a 4.5-kilometre wide caldera. Before the formation of this caldera the volcano may have been 7,000 metres high and thus one of the highest volcanoes on Earth. After the formation of this caldera lava effusion occurred during the Pleistocene and Holocene; there is no reported historical activity, however. Eruption products on Escalante and Sairecabur include andesite and dacite. The climate is dry, cold and very sunny.
