Hornopiren

成層火山 · Chile · 1572m

Symmetrical forested Volcán Hornopirén is seen from the SW from a ferry approaching the town of the same name at the head of a fjord at the NE end of the Gulf of Ancud. The 1572-m-high volcano, whose name means "snow oven," lies along a graben defined by the major regional Liquiñe-Ofqui fault zone. The volcano was said to be in eruption in 1835, although no details are known. Glacier-capped Yate volcano appears in the background to the left of Hornopirén.

地質学的概要

Volcán Hornopirén, located SSW of Yate volcano, is a morphologically youthful basaltic andesite stratovolcano that is mostly forested. The volcano, whose name means "snow oven," lies along a graben defined by the major regional Liquiñe-Ofqui fault zone, N of the Hornopirén strait and immediately S of Lago Cabrera. Prominent lava flows descend beyond the SW base of the volcano and overlie the graben floor. The volcano was said to be in eruption in 1835, although no details are known.

Wikipedia の要約

英語版の要約

Hornopirén is a stratovolcano located in the Andes, in Los Lagos Region of Chile, south of Yate Volcano and east of Apagado or Hualiaque pyroclastic cone. Hornopirén lies on the major regional Liquine-Ofqui Fault. The volcano is said to have erupted in 1835, although no details are known. The name of the volcano derives from the Spanish word for oven, horno and the native Mapudungun word for snow pirén, thus Hornopirén means snow oven.
