Palomo volcano

Palomo is a small stratovolcano in central Chile, 130 km south of Santiago, and west of the massive Caldera del Atuel. The summit is largely ice-covered. Its young morphology suggests that its last eruptions are relatively recent, perhaps prehispanic, but there has not been any known historic activity.

Background:

The volcano is partially eroded by glaciers. A NE-flank cone, Andres, is postglacial in age and has produced andesitic lava flows. Palomo lies and was constructed within double calderas 3 and 5 km in diameter. The largely ice-covered Palomo has erupted basaltic-andesite to dacitic lava flows; a double crater indicates migration of activity to the NE.
