Corcovado

Stratovulcano · Chile · 1826 m

The dramatic summit spire of Volcán Corcovado is seen here in an aerial view from the south. Two of a string of lakes on its eastern side appear in the background. Corcovado, probably of late-Pleistocene age, is eroded by glaciers and surrounded by Holocene cinder cones. Eruptions were reported in historical time from these flank cones. Darwin observed activity from the Corcovado area in 1834, and an eruption was reported to have occurred in November 1835.

Sintesi geologica

Little is known of this isolated volcano that was seen in eruption by Darwin in 1834, and an eruption was reported to have occurred in November 1835. Corcovado, probably of late-Pleistocene age, is eroded by glaciers and surrounded by Holocene cinder cones. A series of lakes flank the eastern side of the basaltic to basaltic andesite structure. Eruptions in historical time were considered likely from these postglacial volcanoes (Moreno 1985, pers. comm.).
