The main goal of INDES-MUSA project is the establishment of integrated tools and models for large-scale multi-risk assessment in urbanized environments prone to ground subsidence and seismic motion by means of innovative, multi-sensor and cost effective monitoring solutions. Risk and vulnerability of urban areas to the above natural hazards constitute aninherently spatial problem leading by definition to an emerging need for corresponding urban-scale and highly-accurate monitoring schemes that can be used by end-users and decision-making authorities for risk management, disaster preparedness, environmental resource management and future urban planning. The above concept becomes particularly valuable in the case of complex urban landscapes containing different typologies of residential structures, critical facilities and civil infrastructures. In this context, the INDES-MUSA project aims at providing readily available monitoring data in the form of spatial distribution models related to ground subsidence and seismic motion through a web GIS service applied in properly selected urban sites in Greece and China, meeting mutual scientific and practical needs of both countries for multi-risk mitigation strategies. For this reason, particular regions were selected in Greece and China, respectively, presenting great scientific and monitoring interest that is directly related to the objectives of the project referring to soil subsidence and seismic motion effects. The Greek area under investigationis specified in the broader region of Kalochori located close to Thessaloniki in North Greece. Referring to geological aspects, the Kalochori region constitutes a tectonic graben covered by Quaternary and Neogene deposits of great thickness, consisting mainly of marine and lacustrine sediments.
