Osorno Volcano, Chile

The symmetrical, glacier-clad Osorno stratovolcano forms a renowned landmark between Todos Los Santos and Llanguihue lakes.

It is seen here from the north, with Calbuco volcano visible at the extreme right.

The 2652-m-high Osorno is one of the most active volcanoes of the southern Chilean Andes.

Flank scoria cones and fissure vents, primarily on the west and SW sides, have produced lava flows that reached Lago Llanguihue.

Historical eruptions have originated from both summit and flank vents.

The symmetrical, glacier-clad Osorno volcano forms a renowned landmark that towers over Todos los Santos and Llanquihue lakes.

Osorno was constructed over a roughly 250,000-year-old eroded stratovolcano, La Picada, that has a mostly buried 6-km-wide caldera.

La Picada underlies Osorno on the NE and has postglacial maars and scoria cones.

The 2652-m-high dominantly basaltic to basaltic-andesite Osorno is one of the most active volcanoes of the southern Chilean Andes.

The conical volcano contains two small dacitic lava domes on the NW and SSE flanks.

Flank scoria cones and fissure vents, primarily on the west and SW sides, have produced lava flows that reached Lago Llanquihue.

Frequent explosive eruptions including pyroclastic flows and surges have occurred during the past 14,000 years.

Historical eruptions at Osorno have originated from both summit and flank vents and have produced basaltic and andesitic lava flows that have entered both Llanquihue and Todos los Santos lakes.
