Puyuhuapi volcano

cinder cones 524 m / 1,719 ft
Southern Chile and Argentina, South America, -44.3°S / -72.53°W
Current status: dormant (1 out of 5)
Typical eruption style: strombolian, effusive
Puyuhuapi volcano eruptions: unknown, within the past 10,000 years
Puyuhuapi volcano is a chain of basaltic cinder cones in southern Chile, at the head of Puyuhuapi fjord. The cones were formed on 2 NE-SW trending eruptive fissures.

Background:

The larger group consists of 4 cones on the western side of Puyuhuapi fjord and fed lava flows that traveled SE to the sea. The second fissure formed another chain of 4 smaller cones between the head of the fjord and Lake Risopatrón to the north.
The two fractures are related to the regional Liquiñe-Ofqui fault zone. The Puyuhuapi cinder cones are extremely well preserved, suggesting a very young age.
