and andesite lava flows generated during these eruptions reached both Lago Llanquihue and Lago Todos Los Santos. The upper slopes of the volcano are almost entirely covered in glaciers despite its very modest altitude and latitude, sustained by the substantial annual snowfall in the very moist maritime climate of the region. Osorno has also historically produced pyroclastic flow, since it is a composite volcano. The volcano has been noted for its similar appearance to Mount Fuji in Japan.
