The study analyzes the use of InSAR technology and validated data for risk management and natural disaster impact assessment, focusing on the subsidence in Bucharest, associated with underground works and activities, and earthquakes. The TerraSAR-X and TanDEM-X satellites provide crucial information for rapid mapping, spatial analysis, and thematic mapping, supporting effective responses to earthquakes, floods, and other hazards. The analysis identifies ground changes based on radar data using techniques such as Persistent Scatterers (PS) and Small Baseline Subset (SBAS). The study integrates decision analysis into the ILWIS software, using the multi-criteria method (SMCE) to assess vulnerabilities along the M5 Metro Line. The methodology involves structuring problems, evaluating alternatives, and prioritizing solutions, demonstrating the applicability of innovative tools in reducing urban risks. The results highlight the importance of advanced technologies in risk prevention and management, providing recommendations for reducing the impact of subsidence and improving urban planning. There is a clear need for integrated, rapid, and accurate approaches to respond to the more frequent and complex challenges in contemporary society based on validated data and modern technologies.
