Osorno Volcano is a 2,652-metre (8,701 ft) tall conical stratovolcano lying between Osorno Province and Llanquihue Province, in Los Lagos Region of Chile. It stands on the southeastern shore of Llanquihue Lake, and also towers over Todos los Santos Lake. Osorno is known worldwide[ citation needed ] as a symbol of the local landscape, and is noted for its similar appearance to Mount Fuji.

Contents

Osorno is one of the most active volcanoes of the southern Chilean Andes, with 11 historical eruptions recorded between 1575 and 1869. The basalt and andesite lava flows generated during these eruptions reached both Llanquihue and Todos los Santos Lakes. The upper slopes of the volcano are almost entirely covered in glaciers despite its very modest altitude and latitude, sustained by the substantial snowfall in the very moist maritime climate of the region. This mountain also produces pyroclastic flow, since it is a composite volcano.

Osorno sits on top of a 250,000-year-old eroded stratovolcano, La Picada, with a 6-km-wide caldera. [2]

Marmolejo mountain

Volcán Marmolejo is a 6,108 m (20,039 ft) high Pleistocene stratovolcano in the Andes on the border between Argentina and Chile. It is located 9 km (6 mi) NNE of the active San José volcano, and is the southernmost 6,000 m (19,685 ft)-plus peak in the world.

Copahue stratovolcano nestled on the border between Argentina and Chile

Copahue is a stratovolcano in the Andes on the border of Bío Bío Region, Chile and Neuquén Province, Argentina. There are nine volcanic craters along a 2 km (1.2 mi) line, the easternmost of which is historically the most active, and contains a 300 m (1000 ft) wide crater lake with a pH ranging between 0.18 and 0.30. Eruptions from this crater lake have ejected pyroclastic rocks and chilled liquid sulfur fragments. Although the lake emptied during the 2000 eruption, it later returned to its previous levels. Copahue means "sulphur waters" in Mapuche.

Reventador mountain

Reventador is an active stratovolcano which lies in the eastern Andes of Ecuador. It lies in a remote area of the national park of the same name, which is Spanish for "exploder". Since 1541 it has erupted over 25 times, although its isolated location means that many of its eruptions have gone unreported. Its most recent eruption began in 2008 and is ongoing as of July 4, 2017. The largest historical eruption occurred in 2002. During that eruption the plume from the volcano reached a height of 17 km and pyroclastic flows went up to 7 km from the cone.

Todos los Santos Lake lake in Los Lagos, Chile

Lake Todos los Santos is a lake located in the Los Lagos Region of southern Chile, 96 km northeast of the regional capital Puerto Montt and 76 km east of Puerto Varas, within the boundaries of the Vicente Pérez Rosales National Park. It has a surface area of 178.5 km² and a maximum depth of 337 m. The Lake's National Park status has ensured protection to its environment. The catchment is largely covered with old-growth Valdivian temperate rain forests. The present form of the lake is the result of glacial and volcanic processes.

Puntiagudo-Cordón Cenizos

Puntiagudo-Cordón Cenizos is a snow-capped volcanic chain located in the Andes, in Los Lagos Region of Chile, near Volcán Osorno. It lies between Rupanco Lake and Todos los Santos Lake. "Volcán Puntiagudo" is a stratovolcano with a prominent 2,493 m high sharp-pointed summit that results from glacial dissection and gets its name from this feature. According to locals, the Puntiagudo volcano lost some of its sharp point in the earthquake of 1960. So the volcano was more pointed than it is today. Puntiagudo is also given the name Cerro Cenizas.

Mocho-Choshuenco

Mocho-Choshuenco is a glacier covered compound stratovolcano in the Andes of Los Ríos Region, Chile. It is made of the twin volcanoes Choshuenco in the northwest and the Mocho in the southeast.
