Geodetic data can detect and estimate deformation signals rates due to natural anthropogenic phenomena. In the present study, we focus on northeastern Italy, an area characterized by ~1.5–3 mm/yr of convergence collision Adria-Eurasia plates active subsidence along coasts. To define trends tectonic signals, use a Multi-Temporal InSAR (MT-InSAR) approach called Stanford Method for Persistent Scatterers (StaMPS), which is based detection coherent temporally stable pixels in stack single-master...
Sinkholes linked to cover evaporite karst in urban environments still represent a challenge terms of their clear identification and mapping considering the rehash man-made structures. In present research, we have proposed tested methodology identify subsiding features through an integrated non-invasive multi-scale approach combining seismic reflection, PS-InSAR (PSI), leveling full 3D Ground Penetrating Radar (GPR), thus overpassing limits each method. The analysis was conducted small...
Ground displacement measurements are fundamental for investigating the surface effects of numerous natural and anthropogenic processes acting within same region. Spatial geodesy measures ground due to sum multi-scale processes, i.e. that occur at different spatial temporal scales. The joint action these phenomena can generate deformations characterized by constant trends or transients over time even cyclical variations seasonal signals in series, with an annual multi-annual period....
<p>Geodetic data provide useful information on surface deformation over long period of time. Applying time series methods to geodetic data, several phenomena were studied. In particular, the potentials exploited detect and measure slow tectonic signals such as interseismic strain accumulation. During period, when faults are locked, an accumulation can occur in response active stresses. Considering that energy be released through earthquakes, estimation long-term rate reveals...
