Integrated monitoring solutions constitute a prerequisite towards risk mitigation and urban planning policies against soil subsidence and seismic motion, providing valuable knowledge and data for investigating the corresponding physical mechanisms.
The above concept lies between the main framework of actions of INDES-MUSA project aiming at the deployment of an innovative multi-sensor system for monitoring in a complementary manner ground deformation and seismic motion in subsidence-prone urban areas.
The integrated nature of the proposed monitoring scheme will be provided by a combination of Airborne Lidar missions, mobile GNSS stations, a tide gauge and water level sensors for ground subsidence measurements complemented by permanent accelerographic and GNSS stations for monitoring seismic motion. The above multi-sensor scheme will be deployed as an innovative pilot study, based on available means, in properly selected urban sites in Greece and China. The Greek site under investigation is located in the region of Kalochori close to Thessaloniki in North Greece, presenting great scientific and monitoring interest related to the examined natural hazards, thereby in agreement with the general objectives of the proposed project. Besides monitoring and data processing, soil subsidence and seismic motion will be investigated by means of pertinent methods of analysis that will be developed and adapted in an urban-scale sense aiming at a better understanding of the investigated hazard sources as affected by the urban environment. Both recorded data and analysis predictions will be integrated, combined and implemented towards the development of a research tool that will be made readily-available and accessible to the scientific community and local/national decision-making authorities during the project through a properly designed Web platform. The project is expected to have a direct benefit to the participating enterprises and research teams based on a profitable technical know-how or/and scientific personnel exchange between the two countries.
