What caused the Puyehue volcano to erupt in 2011?

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 did Puyehue Cordon Caulle form?

Cordón Caulle evolved during this time from being a shield volcano to a graben with fissure vents. This was accompanied by emission of ignimbrites and dacitic lava flows. Puyehue was characterized by eruption of basaltic andesites to dacites until its activity turned bimodal at around 34,000 years ago.

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.

When did Puyehue Cordon Caulle last erupt?

2012Puyehue-Cordón Caulle / Last eruption

What happens if you jump in lava?

The extreme heat would probably burn your lungs and cause your organs to fail. “The water in the body would probably boil to steam, all while the lava is melting the body from the outside in,” Damby says. (No worries, though, the volcanic gases would probably knock you unconscious.)

What are the 3 main volcanoes?

What are the three main volcanoes? There are three main types of volcano – composite or strato, shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows.

Where is Puyehue Cordon Caulle located?

central Chile
Puyehue-Cordón Caulle Volcano is located in central Chile. The group consists of Puyehue volcano and Cordón Caulle fissure complex. Puyehue volcano contains a 2.4 km wide summit caldera and lava flows and domes on the eastern flank. Historical eruptions have occurred at Cordón Caulle rift zone.
