Putana

關於

Volcán Putana, sometimes referred to as Jorqencal or Machuca, is a stratovolcano located in the Central Volcanic Zone (CVZ) of the Andes on the border between Bolivia and Chile and close to the Sairecabur volcanic complex. Its summit is 5,884 metres (19,304 ft) above sea level and contains a summit crater with two smaller craters nested within it. Beneath the summit, the volcano features a number of lava domes and lava flows, some of which originated in flank vents.

While the occurrence of historical activity is unclear (aside from an episode in 2009–2010 where the edifice was uplifted by 4 centimetres (1.6 in)), the volcano features persistent and vigorous fumarolic activity that creates a large plume of gas above the summit. Sulfur deposited by the fumaroles has been mined.
