AbstractIn this study we applied the advanced Multidimensional Small Baseline Subset (MSBAS) InSAR technique to measure ground deformation with high temporal and spatial resolution, and with high precision. We used 2003-2010 ENVISAT and 2008-2013 RADARSAT-2 satellite radar images and produced time series of vertical and horizontal (east-west) components of deformation. Ground deformation results cover the entire Naples Bay area, in particular Campi Flegrei and nearby Vesuvius volcano. Starting from June 2010 we observed moderate uplift at the Campi Flegrei caldera. The rate of uplift substantially increased in 2011 and further accelerated in 2012-2013. Between 2010 and 2013 the maximum cumulative uplift reached about 13 cm and the horizontal motion reached about 7 cm. At Mt Vesuvius we observed long term subsidence with a nearly constant rate and well-defined seasonal oscillations.
Summary(Plain Language Summary, not published)
Ground deformation (e.g. subsidence, uplift) produced by natural (earthquakes, volcanic eruptions) and anthropogenic (bridge and building collapses) disasters is one of the largest sources of casualties and damage to infrastructure around the world. The most cost-efficient tool for monitoring natural and anthropogenic hazards over large regions is space-borne Synthetic Aperture Radar (SAR) and Canada operates the most advanced SAR satellite in the world - RADARSAT-2. To further improve processing methodologies that are used for monitoring ground deformation here we investigated land uplift in Naples region of Italy that currently is undergoing active ground deformation due to volcanic inflation. The space-based technique successfully identified seismic-related uplift and subsidence in the study region, along with related seasonal variability.
