With the launch of Sentinel-1, advanced interferometric measurements will become more applicable then ever. The foreseen
standard Wide Area Product (WAP), with its higher spatial and temporal resolution than comparable SAR missions,
will provide the basement for the use of new wide scale and multitemporal analysis. By now the use of SAR interferometry
methods with respect to risk assessment are mainly conducted for active tectonic zones, plate boundaries, volcanoes as
well as urban areas, where local surface movement rates exceed the expected error and enough pixels per area contain a
relatively stable phase. This study, in contrast, aims to focus on infrastructural sites that are located outside cities and are
therefore surrounded by rural landscapes. The stumbling bock was given by the communication letter by the European
Commission with regard to the stress tests of nuclear power plants in Europe in 2012. It is mentioned that continuously
re-evaluated risk and safety assessments are necessary to guarantee highest possible security to the European citizens and
environment. This is also true for other infrastructural sites, that are prone to diverse geophysical hazards. In combination
with GPS and broadband seismology, multitemporal Differential Interferometric SAR approaches demonstrated great
potential in contributing valuable information to surface movement phenomenas. At this stage of the project, first results
of the Stamps-MTI approach (combined PSInSAR and SBAS) will be presented for the industrial area around Priolo Gargallo
in South East Sicily by using ENVISAT ASAR IM mode data from 2003-2010. This area is located between the
Malta Escarpment fault system and the Hyblean plateau and is prone to earthquake and tsunami risk. It features a high
density of oil refineries that are directly located at the coast. The general potential of these techniques with respect to the
SENTINEL-1 mission will be shown for this area and a road-map for further improvements is given in order to overcome
limitations that refer to the influence of the atmosphere, orbit or DEM errors. Further steps will also include validation and
tectonic modeling for risk assessment.
