Analysis of the evolution of ground movements in a low densely urban area by means of DInSAR technique

This paper presents an application example of the use of the Differential Interferometry Synthetic Aperture Radar technique (DInSAR) for monitoring ground movements in a geologically complex area around the village of Súria (Ebro Basin, Catalonia, NE Spain), associated to underground mining activities and to the presence of a salt dome. The analysis has been mostly performed in a rural environment affected by ground movements with different patterns, magnitudes and causes. A total of fifty SAR images recorded between 1995 and 2007 were processed to generate the interferograms. In order to study the non-linear trends or changes of the ground surface behavior, the DInSAR technique was applied in two sets of images.
