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.
The eruption was fed by a 5.5 km (3 mi) long and north west-west (N135°) trending fissure along which 21 individual vents have been found. These vents produced an output of about 0.25 km 3 DRE both in form of lava flows and tephra. The eruption began in a sub-plinian style creating a column of volcanic gas, pyroclasts and ash about 8 km in ...
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 ...
The 2011–2012 Puyehue-Cordón Caulle eruption was a volcanic eruption that began in the Puyehue-Cordón Caulle volcanic complex in Chile on 4 June 2011. The eruption, which occurred from the Cordón Caulle fissure after 51 years of the volcano being inactive, is one of the largest volcanic eruptions of the 21st century thus far. [ 2 ]
The Apacheta-Aguilucho volcanic complex lies in northern Chile, close to the border with Bolivia. [3] The city of Calama lies 105 kilometres (65 mi) [4]-120 kilometres (75 mi) southwest of Apacheta-Aguilucho and El Tatio is about 60 kilometres (37 mi) south-southwest, but with the exception of geothermal power [2] and mining-associated infrastructure the area is remote and uninhabited.

Volcán Putana, sometimes referred to as Jorqencal or Machuca, is a stratovolcano located In the Central Volcanic Zone (CVZ) of the Andes on the border between Bolivia and Chile and close to the Sairecabur volcanic complex. Its summit is 5,884 metres (19,304 ft) above sea level and contains a summit crater with two smaller craters nested within it.
The eruption poured over 17 million tons of the gas into the atmosphere and led to a global temperature decrease of around 0.5 degrees Celsius (0.9 degrees Fahrenheit) that lasted about a year ...
The South Volcanic Zone is the most volcanically active region in Chile, and produces around one eruption per year. Its largest historical eruption was at Quizapu Crater, located 15 kilometres (9 mi) to 20 kilometres (12 mi) from the north side of Cerro Azul's summit, [5] and its most active volcanoes are Llaima and Villarrica.
