The Riskcoast project will be introduced and the first results presented. Over those landslides a damage mapping has been generated based on field surveys, and then analysed together with the spatial gradient of displacement derived by the InSAR results. Then, after a classification of the detected areas, a more detailed analysis has been done over some selected costal landslides. Starting from those results a rapid and semi-automatic extraction of the most significant active displacement areas (ADA) has been performed.
The velocity map including the estimation of the displacement time series have been produced over the whole area by processing 139 radar images of the Sentinel-1 (A and B). The presented work is as an example of multi scale (medium to large) application of InSAR for geohazard applications. Riskcoast has been funded by the Interreg Sudoe Programme through the European Regional Development Fund (ERDF). In this work, we present the first results developed in the framework of the project Riskcoast (SOE3/P4/E0868) over an area of around 4 km 2 in AndalucĂa (Spain), including the city and the coast of Granada. Many European and national projects have been financed in order to investigate and improve the processing performances and broaden the operational use and application of the results. Moreover, since 2014, the free and constant availability of Sentinel-1 data has been helping the tendency of using more and more this technique in the institutional risk management activities. Its application ranges from regional/national scale to a very detailed scale, up to a single building analysis. The InSAR technique has been proved to be a powerful tool in order to detect, monitoring and analyse movements related to geological phenomena.
