Hornopirén

Hornopiren

성층화산 · 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.

지질학적 요약

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.
