Global Volcanism Program | Image GVP-11382

Lanín volcano rises to the south above a grove of distinctive Araucaria trees near the Chile/Argentina border.  The beautifully symmetrical, 3737-m-high Lanín towers 2500 m above its base.  The prominent shoulder area on the upper western (right horizon) and northern flanks hint at a buried caldera.  The volcano was formed by dominantly effusive basaltic-to-trachydacitic eruptions at the eastern end of a NW-SE-trending volcanic group beginning with Villarrica on the west that is transverse to the Andean chain.
