National scale surface displacements mapped via the P-SBAS DInSAR processing of sentinel-1 data

The large and continuous availability of Sentinel-1 satellite data is a key factor for developing operational monitoring services at both local and global scale. In this work we present a national scale DInSAR analysis of the Italian territory. To this aim we exploit the Parallel Small BAseline Subset (P-SBAS) approach that allows us to generate large spatial scale deformation maps and corresponding displacement time series in an efficient, automatic and systematic way. Achieved results demonstrate the high capability of Sentinel-1 and DInSAR technique to become effective tools for monitoring the ground displacements at wide spatial scale, with important implications in risk management and mitigation.
