The Sbas-dinsar Approach for the Spatial and Temporal Analysis of Sinkhole Phenomena
Sinkholes represent the main hazards in karst areas, and are related to presence of natural and anthropogenic cavities. In order to mitigate the risk related to sinkholes, identification of likely premonitory signs preceding the catastrophic phase of collapse may be extremely important. Remote sensing and surface monitoring can be used at this aim: multi-pass spaceborne Differential Synthetic A...
متن کاملSurface Deformation Monitoring in Permafrost Regions of Tibetan Plateau Based on Alos Palsar Data
The permafrost region of Qinghai-Tibet Plateau is widely distributed with the freeze/thaw processes that cause surface structural damage. The differential interferometry synthetic aperture radar (DInSAR) can detect large scale surface deformation with high precision, thus can be used to monitor the freeze/thaw processes of frozen soil area. In this paper, the surface deformation pattern of Qing...
متن کاملA Quantitative Assessment of DInSAR Measurements of Interseismic Deformation: The Southern San Andreas Fault Case Study
We investigate the capabilities and limitations of the Differential Interferometric Synthetic Aperture Radar (DInSAR) techniques, in particular of the Small BAseline Subset (SBAS) approach, to measure surface deformation in active seismogenetic areas. The DInSAR analysis of low-amplitude, long-wavelength deformation, such as that due to interseismic strain accumulation, is limited by intrinsic ...

13 This contribution illustrates the advantages of integrating conventional 14 geomorphological methods with InSAR, ground penetrating radar and trenching for 15 sinkhole mapping and characterization in a mantled evaporite karst area, where a 16 significant proportion of the karstic depressions have been obliterated by artificial fills. 17 The main practical aim of the investigation was to eluc...
متن کاملSurface deformation analysis of the Napoli bay (Italy) area: sixteen years of ERS and ENVISAT DInSAR observations
Differential Synthetic Aperture Radar Interferometry (DInSAR) is a microwave remote sensing technique that allows us to investigate surface deformation phenomena with a centimeter to millimeter accuracy with a large spatial coverage capability. Firstly applied to investigate single deformation events, the DInSAR algorithms have further been developed to analyze the temporal evolution of the det...
