The project aimed to enhance the capabilities for identifying, monitoring, and mitigating landslide-related risks in Georgia through the advanced interpretation of InSAR data. The project was carried out by TRE ALTAMIRA in collaboration with IMAGEO and HydroDiagnostics on behalf of the National Environmental Agency of Georgia.
The analysis of satellite interferometric data enabled the identification of numerous point clusters highlighting ground displacement, signaling active slope instability. Through geomorphological interpretation, approximately 9,000 landslide polygons were identified and classified according to the possible sliding mechanisms.
The results were then compared with existing landslide inventories, confirming known phenomena and integrating them with new active areas. This contributed to updating the landslide event database and supporting the geological risk monitoring system at a national scale.
Based on the initial screening, 11 pilot cases involving high-risk active landslides were identified. These cases underwent in-depth analysis via LiDAR and photogrammetric surveys, geological and geotechnical investigations, geomorphological modeling and analysis.
Furthermore, for each pilot area, an Early Moniutoring System was designed to monitor surface and underground displacements, as well as piezometric levels. These ground-based monitoring systems have been operational since August 2025.
