The country's National Geology and Mining Service lists 90 active volcanoes. [2] The volcanoes of the Andes originate from the subduction of the Nazca Plate under the South American Plate, while the volcanoes of Chile's Pacific islands formed from magma coming from three distinct hotspots, Easter, Juan Fernández and San Felix hotspots. The ...
Image of the rhyolitic lava dome of Chaitén Volcano during its 2008–2010 eruption.. Chaitén is a volcanic caldera 3 kilometres (2 mi) in diameter, 17 kilometres (11 mi) west of the elongated ice-capped Michinmahuida volcano and 10 kilometres (6 mi) northeast of the town of Chaitén, near the Gulf of Corcovado in southern Chile.
Copahue (Spanish pronunciation:) 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.

The last explosive eruption of the volcano, based on historical records, occurred in 1877. This detailed astronaut photograph of Llullaillaco illustrates an interesting volcanic feature known as a coulée (image top right). Coulées are formed from highly viscous, thick lavas that flow onto a steep surface.
The eruption began in a sub-plinian style creating a column of volcanic gas, pyroclasts and ash about 8 km in height. The erupting N135° trending fissure had two craters of major activity emplaced at each end; the Gris Crater and El Azufral Crater. Volcanic vents of Cordón Caulle that were not in eruption produced visible steam emissions.
Monte Burney is on the northwest Muñoz Gomera Peninsula. [4] This area lies in the Patagonian region of Chile, [1] which is known for its spectacular fjords. [4] The volcano lies in the commune of Natales [2] 200 kilometres (120 mi) northwest of Punta Arenas, [1] and approximately 100 kilometres (62 mi) southwest of Puerto Natales. [5]
The volcano lies in the Putre municipality, [10] Arica y Parinacota Region. [a] It is located south of Lake Chungará [10] and 4 km (2.5 mi) west of Cerro Capurata. [12]The latter is part of the Nevados de Quimsachata volcano chain which includes Umurata, Acotango and Capurata; [13] sometimes Guallatiri is considered to be part of the Nevados de Quimsachata.
