ABSTRACT
Interferometric synthetic aperture radar (InSAR) is an efžcient technique to precisely measure deformation over large areas at high spatial resolution (Amelung et al. 1999; Crosetto et al. 2002; Fruneau and Sarti 2000; Strozzi et al. 2001; Tesauro et al. 2000). Highly correlated radar images are integrated together in order to generate interferograms containing precise deformation measurements. The InSAR technique is able to map the extent and pattern of the ground surface deformation. Moreover, time series analysis of a signižcant number of interferograms can be used in order to study the temporal evolution of the detected phenomena. InSAR time series analysis has been widely used to study the short-term as well as the long-term
