“…For instance, successful terrain deformation estimates have demonstrated the usefulness of this technique for a wide range of applications related to tectonic (Vilardo et al, 2010;Funning et al, 2007;Lanari et al, 2007;Bürgmann et al, 2006;Musson et al, 2004) and volcanic activity (Hooper et al, 2004(Hooper et al, , 2007, landslides (Bovenga et al, 2012;Bovenga et al, 2006;Hilley et al, 2004;Colesanti et al, 2003), land subsidence caused by groundwater pumping (Heleno et al, 2011;Bell et al, 2008;Stramondo et al, 2007;Tomás et al, 2005) and mining (Jung et al, 2007;Colesanti et al, 2005), or urban planning (Cigna et al, 2012;Crosetto et al, 2008;Vallone et al, 2008).…”
