The Scopello area, which is located along the north-western Tyrrhenian coastal sector of theSicilian chain (Italy), is widely affected by Deep-seated Gravitational Slope Deformation(DGSD) phenomena, which are mainly the result of a geomorphologic setting marked by theoutcropping of an overthrust plan, limiting a brittle fractured carbonate slab, laid onto a ductilemarly-clayey substratum. Due to the very advanced stage of the deformation phenomena, acoupled morphodynamic style has established between shallow landslides and DGSDphenomena, affecting the exhumed ductile substratum and the overlaying rigid dismantledslab, respectively. A GPS network was realized for monitoring the Scopello landslide,consisting of 27 vertexes, which were directly cemented either onto rock or debris blocks orconcrete structures rooted on the marly–clayey substratum. The geometry of the network andthe geodetic technique adopted for the GPS signal acquisition allow the survey for a subcentimetricprecision in the positioning of the vertexes. On February 2005 earth-flows andblock/slab-slides movements affected the head sector of the landslide area. The displacementsfield, which was derived by comparing the results of a pre- (2004) and a post-event (2005)GPS surveys, is here analyzed and discussed. On the basis of the observed displacement, theconnection between surficial and deeper ground deformations is confirmed.
