Puyuhuapi

Cono piroclastico · Chile · 524 m

A chain of cinder cones was erupted along NE-SW-trending fissures at the head of Puyuhuapi fjord (top-center) in this NASA International Space Station image (with north to the upper left). The Volcanes de Puyuhuapi consists of a larger group of four cones on the western side of Puyuhuapi fjord and a chain of smaller cones north of the head of the fjord. The two fractures and the fjord are related to the regional Liquiñe-Ofqui fault zone. The town of Puyuhuapi lies on the western side of the fjord, about halfway down its visible length in this image.

Sintesi geologica

A chain of dominantly basaltic cinder cones erupted along two NE-SW-trending fissures at the head of Puyuhuapi fjord comprise the Volcanes de Puyuhuapi. The larger group of four cones lies on the W side of the fjord and fed lava flows that traveled SE to the sea. The second lineament formed a chain of four smaller cones between the head of the fjord and Lake Risopatrón to the N. The two fractures are related to the regional Liquiñe-Ofqui fault zone. The cinder cones are extremely well preserved, suggesting a very young age.
