Cordon de Puntas Negras volcano

estratovolcanes 5852 m / 19,199 ft
Chile / Argentinien (Norden) + Bolivien, Südamerika, -23.74°S / -67.53°W
Current status: normal or dormant (1 out of 5)

Cordón de Puntas Negras is a stratovolcano in northern Chile 46 km SE of Lascar volcano.
The volcano has a number of fresh-looking cones and craters such as Cerros Cenizas, Aguas Calientes, Laguna Escondida, and Chinchilla with well-preserved summit craters and short lava flows. In addition, there is a distinct maar and a large, 13 sq km silicic lava flow and dome complex.
It is thought that some of these vents are less than 10,000 years old, or even historical in age. The youngest of the complex is a crater SE of Cerro Laguna Escondidax.

Background

The Cordón de Puntas Negras chain contains small cones, lava domes, lava flows, and maars and covers an area of 500 sq km and contains at least 25 different vents.
Cordón de Puntas Negras proper is situated along the southern margin of the 35 x 70 km Pliocene La Pacana caldera.
