# FLATSIM: The ForM@Ter LArge-Scale Multi-Temporal Sentinel-1 InterferoMetry Service
## 5 Results and Products Qualification  
### First Processed Areas  
In May 2020, a first call for proposals was open to the French scientific community to identify priority regions for FLATSIM processing. Figure 11 presents all the regions of interest retained for this first call. Nine projects were selected covering different scientific interests. An InSAR expert from the FLATSIM project was attributed to each project. The role of this expert is to interact beforehand with the user to define the key processing parameters. At the end of the processing, the expert helps the user to assess the quality of the generated products. 1. The _Ozark aquifer_ project covers a region located in North America. It focuses on the study of the deformations associated with the Ozark aquifer (south of the Mississippi basin), subject to strong variations in groundwater level, and in neighboring regions where significant seismicity is observed, with a strong seasonal component (New Madrid), or related to wastewater injections (Oklahoma). The objective is to better understand the geodetic signature of the hydrological cycle;
2. The _Central Andes, Peru-Chile_ project aims at (1) better understanding the seismic cycle of the Andean subduction zone in Peru and Chile and of the crustal faults in the Andes, (2) monitoring the dynamics of the large active volcanoes in the region (and to detect possible precursors to eruptions), and (3) at studying the seismic, climatic, and anthropogenic forcing on the dynamics of landslides in the Andes;
3. The _Balkan region_ is one of the most seismically active zones in Europe, with intense industrial and demographic development. The purpose of the project is to better quantify the deformations of tectonic origin in this region (kinematics and localization of active faults, study of earthquakes). It also aims at quantifying the deformations of anthropogenic or climatic origin (linked to the exploitation of natural ressources or to variations in sea level);
4. _Turkey_: The objective of this project is to characterize the seismic and aseismic behavior of the North Anatolian and East Anatolian faults, in order to better assess their seismic hazard and understand the physical processes governing the dynamics of a fault. It also includes the monitoring of deformations in the grabens of western Turkey, which are major geological structures with high seismic potential;
5. The _Afar_ project aims at characterizing the spatial and temporal distribution of the deformation in the region of the Afar depression. The purpose is to better understand the large-scale tectonics (localization of divergent borders, kinematics of the triple point), but also the dynamics of volcanic, seismic, and aseismic events, and the mechanics of active faults. The issue of landslides hazard will also be addressed;
6. _Okwango delta_: This project aims at better understanding the deformations of tectonic origin in the area of the Okwango Delta (associated with the functioning of the Okwango rift and the East African rift), or of hydrological origin (linked in particular to the flood cycle), and the possible interactions between tectonics and hydrology in this region;
* The _Tarin_ project focuses on the analysis of tectonic deformations along the Western Kunlun Range, on the northwestern edge of the Tibetan Plateau. This region is marked by the interaction between large strike-slip and thrust faults, with in particular the existence of one of the largest thrust sheet in the world, whose interseismic loading and capability to produce \"mega-earthquakes\" will be investigated;
* _Eastern border of the Tibetan plateau:_ The objective of the project is to quantify and model the current deformations on the eastern edge of the Tibetan plateau. It focuses on deformations of tectonic origin, at the scale of active faults, as well as at the continental scale, to address issues of the seismic cycle and uplift mechanisms of the Tibetan plateau.
