Seismic mitigation measures are becoming increasingly important in order to support the sustainable development of cities around the world. Disaster Risk Reduction is a consolidated field of study and an integral part of civil protection and construction practices. The definition of strategies aiming at reducing the risk requires two fundamental steps: the first consists of the evaluation of the impact in the current state while for the second, the impact is estimated having adopted appropriate mitigation strategies. The comparison between the losses (of buildings, human lives, and economic) calculated in the two steps defines the effectiveness of the mitigation measures considered. The impact is defined through the consideration of three factors: hazard, vulnerability, and exposure. The hazard is the probability that a fixed event occurs in a fixed period of time; the vulnerability is the probability that an element at risk reach a fixed level of damage; the exposure represents the vulnerability distribution on the invested area. Vulnerability and exposure are strictly connected: with respect to the buildings, the vulnerability depends on their typological and structural characteristics, so the exposure represents the distribution on the investigated area of these building’s features. This paper presents a procedure to define the exposure of the current state of an investigated area through the buildup of a structured database to facilitate the knowledge of the area. The database is populated using the ISTOS survey form, developed and customized by the ISTOS research center on the basis of previous works of the PLINIVS study center. Aim of the build-up of the database is the knowledge on the vulnerability distribution on the territory at the current state to have a start point for considerations on mitigation assumptions.

European cultural heritage (CH) is at risk, threatened by environmental processes strengthened by climate change and anthropogenic pressure. In particular, the slow (landslides, subsidence) and seismic (earthquakes) movements of the soil have a strong impact on the structural stability of our cultural heritage (CH). The actions to be carried out to protect and safeguard CH are in continuous development and this is where the STABLE (STructural stABiLity risk assEssment) project fits. STABLE concerns the design and development of a thematic platform, which combines structural stability models, simulation and damage assessment tools, advanced remote sensing, in situ monitoring technologies, geotechnical and cadastral data sets with the WebGIS application for mapping and long-term monitoring of the CH. The thematic platform, which is the final objective of the project, will therefore support the authorities responsible for the conservation of cultural heritage in the design and implementation of policies for monitoring, preserving and safeguarding our heritage. This will allow effective monitoring and management of CH to prevent or at least reduce the possible irreparable damages. STABLE will coordinate existing skills and research in a synergistic plan of collaborations and staff exchanges to offer a complete transfer of knowledge and training to researchers in the specific area under study. The development of the platform will be the strategy that scientists will have to follow to share and improve CH safeguard methods. It will serve professionals to apply the most advanced technologies in their fields.
