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 ...
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 ...
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 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 volcano is ranked 22 on Chile's national volcano hazard scale. [2] The towns closest to the volcano are Cerro Los Castillos, La Balsa, La Orilla, Las Camelias and Rincón Valdés; [20] renewed eruptions could result in debris flows, eruption columns, lava flows and pyroclastic flows on the volcano and surrounding valleys.

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 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]
