How did Puyehue Cordon Caulle erupt?
1960 Eruption An eruption began at Puyehue-Cordón Caulle Volcano on 24th May 1960. The eruption was probably precipitated by the great earthquake in chile (magnitude 9.5) which occurred on 22nd May 1960. The eruption consisted of an explosive subplinian phase and the formation of a mushroom-like column 8 km high.
What caused the Puyehue volcano to erupt in 2011?
Eruption. On 4 June 2011, an explosion from Cordón Caulle produced a set of plumes, including an ash plume described as 5 km wide and with its top at ~12 km altitude. Portions of the plume bifurcated; at ~5 km altitude a part of the plume drifted S, and at ~10 km altitude parts drifted W and E.
Is Puyehue Cordon Caulle active?
The Puyehue-Cordón Caulle Volcanic Complex is a chain of formations that includes the Puyehue volcano, the Cordillera Nevada caldera, and the Cordón Caulle rift zone. The complex is active, with the last eruption occurring as recently as 1990 and the last major eruption in 1960, both in the Cordón Caulle rift zone.
How many times has Puyehue Cordón Caulle erupted?
Puyehue-Cordón Caulle volcano eruptions: 2011 (4 June)- 2012, 1960, 1934, 1929, 1921-22, 1905(?), 1893(?)
Which type of volcanoes is the most explosive?
Because they form in a system of underground conduits, stratovolcanoes may blow out the sides of the cone as well as the summit crater. Stratovolcanoes are considered the most violent.
Is the Puyehue volcano now dormant or extinct?
Cordón Caulle is a volcanic fissure and has erupted many times in recorded history, most recently in 1960, following the 1960 Valdivia earthquake days earlier, whereas the Puyehue stratocone has remained dormant.

What caused the Puyehue-Cordón Caulle volcano to erupt?
Background: Puyehue-Cordón Caulle Volcano started erupting on 24 May 1960. It is possible, that the eruption was triggered by the great earthquake in Chile (magnitude 9.5; the largest measured earthquake in history) on 22 May 1960. The eruption started with a powerful explosive (subplinian) phase, which formed an ash column 8 km high.
What happened in the Puyehue volcano in Chile?
The 2011–2012 Puyehue-Cordón Caulle eruption ( [puˈʝewe]) 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.
How big was the eruption of Caulle volcano?
Cordón Caulle had a sub-plinian eruption, with a 6.2 kilometres (4 mi) high plume, periodic explosions and seismicity. Ended in February 1922.
Where are the Puyehue and Cordón Caulle?
Like most stratovolcanoes in the Southern Volcanic Zone of the Andean Volcanic Belt, Puyehue and Cordón Caulle are along the intersection of a traverse fracture with the larger north–south Liquiñe-Ofqui Fault.
