Volcan de la Pena
25°4.37′S 68°42.72′W / 25.07283°S 68.71200°W[1] Volcan de la Pena is a volcano in Chile.
Volcan de la Pena is part of the High Andes of Chile, between 25° and 26°30′ degrees south. The Andes there at altitudes over 3,500 metres (11,500 ft) feature a number of volcanoes, as well as products of eruptive activity. The Salar Grande lies east of Chato Aislado. Chato Aislado has been proposed as a geosite location for Chile.[2]
Volcan de la Pena is a 5,247 metres (17,215 ft) high cone that rises from a Miocene ignimbrite plateau, northeast of the Salar de Pajonales. The 12 million years old cone is capped off by a lava dome and has been affected by numerous sector collapses in the past, which have generated hummocky deposits.[3] The largest collapse has a volume of 2.31 cubic kilometres (0.55 cu mi). Most of these deposits are degraded, as are the collapse scars.[1] The total volume of the otherwise little eroded edifice is about 31 cubic kilometres (7.4 cu mi).[4]
