چکیده

We investigate the possibility to apply differential SAR interferometry (DIFSAR) techniques to analyse long term phenomena occurring in volcanic areas. The considered test site is represented by the Etna volcano area located in southern Italy; presented DIFSAR experiments show the existence of a long term deformation effect that can be interpreted as an actively growing anticline, beneath the urban area of Catania, related to the distal motion of Mount Etna’s decollement.

ERS-ENVISAT InSAR deformation time-series: a powerful tool to investigate long term surface deformation of large areas

Satellite time series have already provided key measurements to retrieve information on the dynamic nature of Earth surface processes. We exploit in this work the availability of the large archives of spaceborne Synthetic Aperture Radar (SAR) data acquired by the ERS-1/2 and ENVISAT sensors of the European Space Agency (ESA) during the 1992-2009 time period, in order to investigate long term su...

Inversion of SAR data in active volcanic areas by optimization techniques

The inversion problem concerns the identification of parameters of a volcanic source causing observable changes in ground deformation data recorded in volcanic areas. In particular, this paper deals with the inversion of ground deformation measured by using SAR (Synthetic Aperture Radar) interferometry and an inversion approach formulated in terms of an optimization problem is proposed. Based o...
