Summary:The usage of satellite borne SAR monitoring techniques has become wider spread in the last years due to the data becoming more accessible both for research purposes and commercial projects. The paper presents the correlation between the displacements velocity maps obtained from satellite monitoring and the in-situ measurements (inclinometric and piezometric monitoring). The research site has been chosen to be Galati city escarpment, due to the occurrence of several phenomena producing soil mass instability. The escarpment is mainly an artificial ground structure built about 50 years ago using infill with the purpose of extending and remodel this Danube escarpment, using unfit materials and steep slopes. Also, the existing urban networks are old and faulty, generating spills in the collapsible soils present in the area. These deformations are monitoring on a macro scale using the InSAR system and validated through local insitu monitoring. The research is part of a project financed by the Romanian Space Agency and bears the acronym ILUSTRO.
