“…This technique has been mostly applied for monitoring tectonic motions (Kimura and Yamaguchi, 2000;Bürgmann et al, 2006;Delouis et al, 2002;Johanson and Bürgmann, 2005;Wright et al, 2004;Bürgmann et al, 2002). It has also been used successfully for surface effects of subsidence induced by natural causes or man made activities (Poland et al, 2006;Amelung et al, 1999;Tomas et al, 2005;Dixon et al, 2006;Fernandez et al, 2009). However, InSAR technique, for deformation monitoring, depends a lot on local conditions such as topography, vegetation, atmosphere as well as resolution of data.…”
