Palomo

成層火山 · Chile · 4860m

Palomo is a small, 4850-m-high stratovolcano that is seen here from the NNE rising above ruggedly dissected basement rocks.  Palomo was constructed within double calderas, 3 and 5 km in diameter, respectively.  A flank cone, Andres, is postglacial in age and has produced andesitic lava flows.  Palomo has erupted basaltic andesite to dacitic lava flows.  No historical eruptions are known from Palomo, although its youthful morphology suggests a very young age.

地質学的概要

Palomo is a small stratovolcano that is somewhat dissected by glaciers. A NE-flank cone, Andres, is postglacial in age and has produced andesitic lava flows. The volcano lies W of the massive Caldera del Atuel and was constructed within double calderas 3 and 5 km in diameter. The largely ice-covered volcano has erupted basaltic andesite to dacitic lava flows; the double crater indicates migration of activity to the NE. The youthful morphology suggests a very recent, perhaps pre-Hispanic, age.

Wikipedia の要約

英語版の要約

Palomo is a 4,860 metres (15,940 ft) high Chilean stratovolcano located in the commune of Machali, Cachapoal province, Libertador General Bernardo O'Higgins Region, west of Caldera del Atuel. Together with Tinguiririca it is one of two volcanoes in the region with evidence of Holocene volcanism. The volcano is remote and knowledge on its geology and potential volcanic hazards is limited.
