    This project aims to better understand the seismic cycle of the Andean subduction zone in Peru and Chile and the crustal faults in the Andes, to follow the functioning of the large active volcanoes in the region (and to detect possible precursors to eruptions) , and to study the seismic, climatic and anthropogenic forcing on the dynamics of landslides in the Andes. Three types of products are made available for each orbit portion processed (see <a href="https://formater.pages.in2p3.fr/flatsim/" target="_blank"> detailed description </a> ) - "INTERFEROGRAM": this brings together the differential interferograms, wound and unwound, in radar or terrain geometry, filtered or not, at different resolutions, as well as the atmospheric correction maps used and spatial coherence for each interferogram. - "TIMESERIES": this includes maps of movement in time series and average speed, according to the satellite line of sight (LOS), and quality indices of time series processing. - "AUXILIARYDATA": this directory contains maps indicating the LOS vector, the DTM in radar geometry, at different resolutions, the radar-field geometry transcoding tables, and temporal coherence, as well as a set of figures and parameter files specific to the processing of the time series.
