Volcán Putana, also known as Jorgencal or Machuca, is part of a large, roughly N-S-trending volcanic complex that covers an area of 600 sq km. Vigorous fumarolic activity is visible at the 5890-m-high summit of Putana volcano from long distances. The main edifice, which formed primarily by lava effusion, consists of accumulated postglacial 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. A major eruption of unspecified character was reported in the early 19th century (Rudolph, 1955; Guest 1981, pers. comm.), although González-Ferrán (1995) indicated that no historical eruptions had occurred.

The area around Volcán Putana is seen from the west in this sketch. Putana is part of a large, roughly N-S-trending volcanic complex that covers an area of 600 sq km. Vigorous fumarolic activity (depicted in this sketch) is visible at the 5890-m-high summit of Putana volcano from long distances. The main edifice consists of accumulated postglacial dacitic lava domes and flows mantling an older pre-Holocene volcano. Young dark-colored flows in this sketch descend the western flanks of the volcano.

Putana volcano, also known as Jorgencal or Machuca, lies in the center of this Landsat image. Snow-covered areas are deep blue in this image of the N-S-trending volcanic complex, which covers an area of 600 sq km. The main edifice consists of accumulated postglacial 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. The prominent fan-shaped lava flow at the upper left originated from a flank vent.

Volcán Putana, seen here from the west, shows vigorous fumarolic activity at its 5890-m-high summit. Snow forming a thin diagonal line below and to the right of the summit marks a road leading to a sulfur-mining operation at the summit of the volcano. Putana is also known as Jorgencal or Machuca and is part of a large, roughly N-S-trending volcanic complex that covers an area of 600 sq km along the Chile-Bolivia border. Postglacial dacitic lava domes and short, thick lava flows form the main edifice.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
