The Antillanca group of stratovolcanoes is located 100 km NE of Puerto Montt in central Chile, at the eastern shore of Rupanco Lake. The cluster consists of scoria cones, maars and small stratovolcanoes and covers an area of 380 sq km.
The most prominent volcanic edifice is the Casablanca stratovolcano which erupted about 2910 and 2260 years ago.
Older stratovolcanoes of the Antillanca group include Sarnoso volcano on the SW side and Fiuchá volcano on the NW side.
Geothermal areas are found in various spots on the NW side of the group.
