Analisi del sisma del 6 Aprile 2009 in Abruzzo con tecniche di Interferometria SAR differenziale

Synthetic Aperture Radar (SAR) sensors can provide useful support to the analysis and managing of the natural risks. In particular, SAR Interferometry (InSAR), thanks to its large-scale view area coverage of the deformation field, provides useful measurements for damage assessment of seismic events and fault modelling. The present study is aimed to the application of InSAR techniques for obtaining the co-seismic deformation pattern and inferring the fault model parameters for the Mw=6.3 earthquake which struck the Abruzzo region in Italy on April 6th, 2009. In particular, we used SAR data acquired in C band (wavelength of 5.6 cm) by the European Space Agency (ESA) ENVISAT satellite, and X band (wavelength of 3.1 cm) by the German Space Agency (DLR) TerraSAR-X as well as by the Italian Space Agency (ASI) constellation COSMO-SkyMed. Through the SPINUA processing chain, the co-seismic differential interferograms were generated which record the deformation induced by the seismic event. In the present work we present a comparative analysis of interferometric fringe patterns obtained with different values of wavelength, spatial resolution as well as incident angles.
