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 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 ...
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 volcano usually generates strombolian eruptions with ejection of incandescent pyroclasts and lava flows. Rainfall plus melted snow and glacier ice can cause massive lahars (mud and debris flows), such as during the eruptions of 1964 and 1971. Villarrica is one of 9 volcanoes currently monitored by the Deep Earth Carbon Degassing Project.
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 ]
An 1874–76 eruption caused various lava flows, landslides, lahars, and the fall of volcanic ash. After this eruption the volcano became known as Llaima or Yaima. [6] Prior to that it had been known as Chañel a Mapuche word in reference to the pointy shape of its summit before the eruption. [6] The last major eruption occurred in 1994. [7] An ...
Mocho is an andesitic-dacitic volcano placed above the caldera. [2] Some parasitic craters and cinder cones are located on the southwest and northeast flanks of the stratovolcano. Mocho has its earliest certainly recorded eruption in 1759, older eruptions reported are uncertain due to the usage of different names and inexact maps.
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.
