Puyehue Cordón Caulle Volcano Erupts, Chile Volcanic Eruption Cam Stream

A chain of volcanoes, Puyehue-Cordon-Caulle range has erupted in southern Chile, forcing the evacuation of thousands of residents. Large columns of smoke have been rising from the volcano, about 800km (500 miles) south of the capital Santiago.

This live video footage has been captured of the eruption:

Volcano Information:

Puyehue and Cordón Caulle are two coalesced volcanic vents that form a major mountain massif in Puyehue National Park in the Andes of Ranco Province, Chile. In volcanology this group is known as the Puyehue-Cordón Caulle Volcanic Complex (PCCVC). Four different volcanoes constitute the volcanic group or complex, the Cordillera Nevada caldera, the Pliocene Mencheca volcano, Cordón Caulle fissure vents and the Puyehue stratovolcano. As with most stratovolcanoes on the Southern Volcanic Zone of the Andes, Puyehue and Cordón Caulle are located along the intersection of a traverse fault with the larger north-south Liquiñe-Ofqui Fault. The volcanic complex has shaped the local landscape and produced a huge variety of volcanic landforms and products over the last 300,000 years. Cinder cones, lava domes, calderas and craters can be found in the area apart from the widest variety of volcanic rocks in all the Southern Volcanic Zone, for example both primitive basalts and rhyolites. Cordón Caulle is notable for having erupted following the 1960 Valdivia earthquake, the largest recorded earthquake in history. Apart from this, the Puyehue-Cordón Caulle area is one of the main sites of exploration for geothermal power in Chile. Geothermal activity is manifested on the surface of Puyehue and Cordón Caulle as several boiling springs, solfataras and fumaroles.

Recent activity at the volcano has resulted in alert level 4 (out of 4) being issued on June 3rd, 2011. A new eruption started as of June 3rd 16:30 EDT. As of 4 June, the ash cloud reached a height of 10,000 meters.
