地質学的概要
The Puntiagudo-Cordón Cenizos volcanic chain lies between Lago Rupanco and Lago Todos Los Santos in the Chilean lake district. Volcán Puntiagudo is a late-Pleistocene andesitic stratovolcano with a prominent sharp-peaked summit that results from glacial dissection. An 18-km-long fissure system with more than 40 late-Pleistocene to Holocene basaltic scoria cones and small stratovolcanoes extends to the NE. Lava flows from these centers descend to the NW and SE, in some cases reaching to the shores of the two lakes, forming irregular peninsulas. The only historical eruption occurred in 1850, when ashfall was reported from the Cordón Cenizos chain.
Wikipedia の要約
英語版の要約Puntiagudo-Cordón Cenizos is a snow-capped volcanic chain located in the Andes, in Los Lagos Region of Chile, near Volcán Osorno. It lies between Rupanco Lake and Todos los Santos Lake. "Volcán Puntiagudo" is a stratovolcano with a prominent 2,493 m high sharp-pointed summit that results from glacial dissection and gets its name from this feature. According to locals, the Puntiagudo volcano lost some of its sharp point in the earthquake of 1960. So the volcano was more pointed than it is today. Puntiagudo is also given the name Cerro Cenizas.
