On June 4, 2011, Puyehue-Cordon Caulle complex began its eruptive activity. This intense eruption lasted for several months and was characterized by both effusive and explosive activities. ENVISAT ASAR sensor imaged the eruption of the volcano, and the sin-eruptive surface deformation was estimated by using Differential SAR Interferometry (DinSAR). The present dataset is the result of such estimation, and reports the SAR Line of Sight (LoS) displacement, in metres, related to the first phase of the eruption. In particular, the ASAR images used for DinSAR processing are dated May 08, 2011 and June 07, 2011. The interferogram shows a large deflating area in the Cordon Caulle section of the volcanic complex that reaches a value of -90 cm. Moreover, few centimetres of deflation are also present in the west flank of Puyehue stratocone.
