having been reported as recently as 1992, 1995 and 2000. A deformation analysis using the
Differential Synthetic Aperture Radar technique (DInSAR) was performed on Copahue–
Caviahue Volcanic Complex (CCVC) from Envisat radar images between 2002 and 2007. A
deformation rate of approximately 2cm/yr was calculated, located mostly on the north-
eastern flank of Copahue volcano, and assumed to be constant during the period of the …
