Fueguino volcano

Fueguino (Volcán Cook) volcano is the southernmost active volcano of South America's Andes, located on Isla Cook. It is 400 km away from the nearest other active volcano, Monte Burney to the NW.
The volcano consists of lava domes and cinder cones. A strombolian eruption was observed in 1820.

Background:

Fueguino is a group of andesitic, columnar-jointed lava domes and pyroclastic cones reaching to 150 m height. The volcanoes are located on a broad peninsula forming the SE end of Isla Cook.
One of the cones, south of Bahía del Volcán, contains a 150-m-wide crater with a small lake. The lava domes and pyroclastic cones were possibly emplaced along N-S-trending faults. They are not eroded by glaciers as the basement granite rocks.
