Grounddeformations are the result of a variety of natural and human-induced causes and triggers. These phenomena arefrequent and widespread in Europe, causing extensive economic damage to private properties and public assetsand their social impact is relevant. In Europe, the large number of areas affected by ground deformations, thefrequency and extent of the triggering events, the extent of the impact and the magnitude of the damage, makeit mandatory a multiscale, systemic approach. Further, the complexity and extent of the problem is such that itcannot be tackled (and solved) at an individual, site-specific scale, or using a single technique or methodology.The problem can be approached only through the integration of data and information taken at different scales, andwith the collaborative efforts of multiple expertise. With this respect, the several satellite sensors now available,including about forty passive – optical – sensors and nine active – synthetic aperture radar (SAR) – sensors,provide valuable technological alternatives to traditional methods and tools to detect, map, monitor and forecastground deformations over large areas and with the required accuracy. The temporal continuity and the geometriccompatibility among time series of ERS-1, ERS-2 and ENVISAT data represents an unprecedented opportunityto generate very long time series of ground deformations. This provides exclusive information for an improvedunderstanding of the long term behavior of slow and very-slow ground deformation phenomena.In this context, DORIS intends to exploit the extensive catalogues of multiple C-band SAR sensors to provide, viaa joint analysis, additional information on ground displacements through the generation of very long deformationtime series, spanning an almost 20 year time interval by properly combining ERS-1, ERS-2 and ENVISAT data.In this work we present the preliminary results relevant to selected European areas (Umbria (Central Italy),Nebrodi (Sicily, Southern Italy), Zermatt (Switzerland), Silesian Coal basin (Poland), Mallorca (Spain) andBudapest basin (Hungary)) affected by ground deformation, highlighting as such EO data and technologies cansignificantly improve the ability of European Civil Defence authorities to assess and manage the risk induced bynatural and man-made hazards.
