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 m high; other mountains in the range are 5,722 m high Curiquinca, 5,819 m high Escalante and 5,748 m 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 km wide caldera. Before the formation of this caldera the volcano may have been 7,000 m 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.
