Monitoring deformations related to geological risks with InSaR data – the MOMPA project

Abstract

Abstract Co-financed by the Interreg V Program in Spain-France-Andorra (POCTEFA) the European project MOMPA (MOnitoring of ground Movements and Action Protocol) study the landslide hazard in the Eastern Pyrenees. It groups together scientific partners from CTTC (Telecommunications Centre of Catalonia), ICGC (Cartographical and Geological Institute of Catalunya) IEA (Andorran Research Institute), and Cerema (Centre for studies and expertise on risks, the environment, mobility, and development). This cross-border project provides the expertise of four partners, which are specialized in remote sensing and techniques of risk analysis and management. More specifically, the goal of this project is to improve risk management by evolving from a “reactive” approach to a “proactive” one that is rarely used today because of its financial cost. To identify movements, the technique of interferometric SAR (InSAR) based on satellite images is used. This technique is sensitive to very small ground deformations and allows early detection of movements.
