TimeMag. / DepthDistanceLocation
Volcán Putana (also known as Jorgencal or Machuca) is a stratovolcano in northern Chile on the border with Bolivia. Strong fumarolic activity is present at the summit crater and is visible from far distance, and the volcano has large sulfur deposits.
The volcano, whose name literally means "whore" has (probably) erupted twice in historic times. Its name might allure to a major destructive eruption reported in the 19th century, although some recent research suggests that there actually were eruptions at all in historic times at Putana volcano.

Background:

Putana volcano is part of a large, roughly N-S-trending volcanic complex that covers an area of 600 sq km.
The main edifice consists mainly of dacitic lava domes and flows mantling an older pre-Holocene volcano. The youngest basaltic andesite lava flows are viscous and rarely extend more than 3 km.
