Abstract Deep-seated gravitational slope deformations (DsGSDs) are very slow instabilities that can have a long-term impact on anthropic structures and infrastructures. The characterization of their state activity is, therefore, essential to evaluate it. By employing Differential Interferometry Synthetic Aperture Radar (DInSAR) techniques, dedicated procedure, explore the behavior define 279 Ds...

Knowledge of the subsurface properties driving subsidence is of key importance in conducting geophysical surveys such as self-potential, magneto telluric, and reflection seismic, as this can help defining the areas with downward water flow, collapsed features at depth, or overburden affected regions. However, accurate and affordable subsurface information is difficult to obtain with currently a...

We present here a methodology that allows the combination of GPS and Differential InSAR data for the calculation of continuous three-dimensional (3D) high-resolution velocity maps with corresponding errors. It is based on analytic minimization of the Gibbs energy function, which is possible in the case when neighborhood pixels of the velocity maps are considered independent. By joining scalar D...

This paper deals with the problem of temporal decorrelation in the application of Differential SAR Interferometry (DInSAR) to surface deformation monitoring. Special attention has been paid to the impact of reflectivity changes on the so-called Permanent Scatterers (PS). Semi-PS (SPS) and Temporary PS (TPS) are first defined and possible solutions to their detection are then proposed. The impac...

The permanent scatterers (PS) technique is a multi-interferogram algorithm for DInSAR analyses developed in the late nineties to overcome the difficulties related to the conventional approach, namely, phase decorrelation and atmospheric effects. The successful application of this technology to many geophysical studies is now pushing toward further improvements and optimizations. A possible stra...

Operational monitoring of slope instabilities by SAR Interferometry poses a number of challenges due to the limited spatial extent of the landslide areas and rainy conditions usually associated with mass movement events. In this work we present the results of the application of both conventional DInSAR techniques, and a point-by-point, multitemporal study of the long-term stability of selected ...
