Shifting winds moved the plume in different directions, sometimes over the Pacific and sometimes over South America, where ash … Puyehue is a stratocone volcano (i.e. At 18.45 UTC on June 4 th, 2011, an explosive eruption (VEI ≤ 5) of rhyolitic magma 1,2,3 began at Puyehue-Cordón Caulle volcanic complex (PCCVC), southern Chile and close to the frontier with Argentina. It forms part of the Puyehue-Cordón Caulle Volcanic Complex, along with the Cordón Caulle volcanic fissure and Cordillera Nevada caldera.
A new eruption started on 4 June 2011. The 2011 eruption in the Puyehue-Cordón Caulle volcanic complex deposited up to 50 cm of tephra in a plume that intersected the crest of the Andes along Route 215, offering an excellent opportunity to study disturbance effects on native forests along a gradient of tephra depth.
Puyehue-Cordón Caulle's eruption seen in a long-exposure photo taken during 4-6 June 2011. Above the glowing, molten material there grew a substantial, rapidly rising ash plume. 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. Puyehue-Cordón Caulle's eruption seen in a long-exposure photo taken during 4-6 June 2011. The Puyehue Eruption, Chile, 2011. 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.
The eruption, which occurred from the Cordón Caulle fissure after 51 years of the volcano being inactive, was the largest volcanic eruption of the 21st century thus far. The eruption at Puyehue-Cordón Caulle began on June 4, 2011. NASA Earth Observatory image created by Jesse Allen and Robert Simmon, using EO-1 ALI data provided courtesy of the NASA EO-1 team. Flights in Australia have been disrupted for days as smoke continues to billow from the Chilean volcano chain Puyehue-Cordón Caulle 0:45 Published: 15 Jun 2011 Above the glowing, molten material there grew a substantial, rapidly rising ash plume. Much of the scene is lit by numerous bolts of lightning. The photo depicts molten material discharging over a wide area near the eruption column's base. Caption by Michon Scott and Robert Simmon. After a failed attempt in 1553, governor García Hurtado de Mendoza founded the city of Osorno in 1558, the only Spanish settlement in the zone, 80 kilometres (50 mi) west of Cordón Caulle.

A satellite image collected on March 7, 2012, (above, top) shows a relatively small and diffuse ash plume. 2011 eruption of Puyehue-Cordón Caulle. At 18.45 UTC on June 4 th, 2011, an explosive eruption (VEI ≤ 5) of rhyolitic magma 1,2,3 began at Puyehue-Cordón Caulle volcanic complex (PCCVC), southern Chile and close to the frontier with Argentina. This is explained by the geographical position of Cordón Caulle and the history of Spanish and Chilean settlement in southern Chile. Though less dramatic than the initial eruption in June, Chile’s Puyehue-Cordón Volcano Complex continued releasing ash and steam in early July 2011. This PCC eruption was the first within this dominantly dacitic to rhyolitic fissure zone since 1960 4,5,6,7 (Fig. blew toward the city of Bariloche, Argentina, where the local airport was closed.
