Puyehue-Cordón Caulle. #StratovolcanoSeria 2012 CE Country Volcanic Region Primary Volcano Type Last Known Eruption 40.59°S 72.117°W. 2236 m. 7334 ft nombre 357150 Explosive phases ended in April 2012 and the rhyolitic dome continued to flow ~1 year later The rift zone eruption that began at Puyehue-Cordón Caulle on 4 June 2011 (BGVN 37:03) persisted through early 2012 and declined toward the end of 2012. Relative quiescence was observed through October 2013, which is the end of this reporting period. The Observatorio Volcanológico de Los Andes del Sur-Servicio Nacional de Geología y Minería (OVDAS-SERNAGEOMIN) maintained Red Alert (the highest level in a four-color scale) from 4 June 2011 to #23MarchSeria 2012; declining activity led to a downgrade in the Alert Level on 23 March 2012 to Orange, and then again on 24 April to Yellow. The status remained at Yellow until #16AugustSeria 2012, when it decreased to Green. Green Alert was maintained through the end of this reporting period of October 2013. Early stages of the eruption captured by remote sensing. Based on polar-orbiting satellites, scientists at the Montreal Volcanic Ash Advisory Centre (VAAC) were able to detect the volcanic ash cloud as it circled the southern hemisphere. Using a combination of infrared channels, five satellites contributed to a mosaic of data showing the wide dispersion of volcanic ash over the period of 4-6 June 2011 (figure 8). A mosaic created on 14 June 2011 captured the 4 June 2011 ash as it approached the Chilean coast while, at the same time, a new ash eruption was occurring at Puyehue-Cordón Caulle #CordonCaulleVolcanoSeria #CordonCaulleVolcanoEruptionSeria #ChileVolcanoesSeria #SouthAmericaVolcanoesEruptionSeria #SouthAmericaVolcanoesSeria #EruptionSeria #PuyehueCordonCaulleVolcanoSeria #VolcanoesSeria #04June2011seria #04JuneSeria #2011JuneSeria (Puyehue-Cordón Caulle)
