summit elevation 3774 m
Stratovolcano
Lanin is a large historically inactive stratovolcano located approximately 45 km southeast of Villarrica volcano, Chile.
Rock samples from the volcano consist of basalt and andesite. Most activity at Lanin volcano has come from central vent eruptions.
The most recent eruption 2200 years ago produced small lava dome at
the summit, and a blocky lava flow to the north.
