BeschreibungThe volcano lies at the eastern end of a transverse to the Andean chain NW-SE-trending group of volcanoes starting at Villarrica volcano in the NW.
The symmetrical cone of the 3737-m-high Lanín edifice rises 2500 m above its base. Shoulder areas on the upper flanks suggest that the cone has grown over a now buried caldera.
The volcano was formed in 4 eruptive stages dating back at least 200,000 years. The last 2 stages occurred in the past 10,000 years and the volcano has only dormant at present.
There are uncertain reports of activity after an earthquake in 1906, but these reports are likely to be false. A less than 10,000 years old tuff ring (Volcán Arenal) is located below the SW flank of Lanín in Argentina. A younger lava flow from Lanín extends south into Lago Paimún in Argentina.
