Short summary

The study of active faults is relevant to estimate the seismic hazard of the surrounding area and relies on different methods. In the last decade interferometric synthetic aperture radar (InSAR) techniques have proved to be robust tools to investigate the surface deformation caused by earthquakes. We used the multi-temporal ALOS L-band InSAR data to produce interferograms spanning times before and after the 2009 earthquake (M_w = 6.0) in the Racha region (Georgia).
