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.
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 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.
For the second time in just over a week, Calbuco volcano in Los Lagos, Chile, is erupting. Until last week, the volcano had been dormant for more than forty years. The last eruption, on April 22 ...
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 eruption is the second-largest historic volcanic eruption in Chile, only behind the 1932 Quizapu eruption. [25] With a volcanic explosivity index of 5, [160] it is one of the largest volcanic eruptions of the 20th century. [21] It formed a 12-kilometre-high (7.5 mi) eruption column and pyroclastic flows within the caldera. [161]

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 ]
