Tocorpuri

About

Tocorpuri is a volcano on the border between Chile and Bolivia. Its peak height is most recently given as 5,808 metres (19, 055 ft) and it features a 1.3 kilometres (0.81 mi) wide summit crater. The volcano consists mainly of lava flows and pyroclastic deposits and is subdivided into two separate edifices. Just west of Tocorpuri, the La Torta lava dome is a 200 m (660 ft) high flat-topped structure. The volcanoes are formed by andesitic, dacitic and rhyolitic rocks. The Tocorpuri volcanoes developed in the late Pleistocene in three separate stages and were subject to glaciation and tectonic faulting. The most recent eruption generated the La Torta lava dome 34,000 ± 7,000 years ago; presently there is geothermal activity which may be connected to that of the neighbouring El Tatio geothermal field.
