SAR interferometry has been applied to the Algarve region of southern Portugal which is an area characterised by a significant regional tectonic activity, evidenced by neotectonic deformation and seismicity. This technique proved to be a useful tool in active tectonic investigation for this region, since it has allowed the detection of active movements mainly coincident with active faults and/or with areas of seimicity concentration. Field studies should be oriented to the locations where interferometric anomalies have been detected.
