Abstract

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.
