Differential SAR interferometry for the study of slope instability at Maratea, Italy

In this paper we explore the use of differential synthetic aperture radar interferometry to improve our knowledge of the slope instability of a well investigated area (the Maratea Valley) affected by continuous slow movements. In particular, by using this technique we analyse the time evolution of terrain movements from 1997 to 2000, a time interval already explored using distancemeter (EDM) and GPS measurements. Results obtained by means of different techniques have been compared, and all the acquired data turn out to be consistent.
