Risk is materialising more and more following more complex and interconnected pathways due to different reasons: Climate Change, increased population density, increased social interconnection and fragility. In that way, fatalities and economic losses due to natural disasters have increased during the last years, not only due to the former reasons but also to the consequent concatenation of possible series of cascade events. As a specific situation of exposed elements, Cultural Heritage (CH) represents the identity of a given territory in a specific time. Natural Hazards and geomorphological process played a fundamental role for their build and conservation. In order to understand safety, stability and conservation conditions, one of the main pillars is provided by the monitoring, analysis, assessment and management. The assessment and mitigation of the impact of natural hazards and their connectivity is a very important scope of analysis. It is necessary to develop new studies to quantify the risks and the relationship between different hazards affecting a given area in order to understand their connections and to provide a better evaluation of the susceptibility and the vulnerability. Understanding risk in a holistic sense and with the help of new technologies is becoming a global priority in order to increase social resilience. The most advanced hazard and risk assessment model, low impact monitoring techniques and the sustainable mitigation measures, should be adopted to define the present conservation condition and the future dynamics affecting exposed elements in general and the CH in detail. In particular, the aim of this session is to discuss novel studies and new approaches in hazard characterisation and risk assessment that make use of Earth Observation data of different nature applied to the monitoring of all exposed elements with a specific focus on Cultural Heritage. The intention is to consider a number of questions and challenges in hazard and multi-hazard risk assessment and mitigation always with the assistance of satellite data; how satellite data can improve the modelling of extreme events and the contribution to hazard studies? in the integration of different hazards and risks into common frameworks; how can different risks be compared and connected between them thanks to the use of EO data? in the development of tools and platforms for assessment and validation of hazard models. Novel case studies which address single or multi-hazards and risk assessment and management assisted by the use of Earth Observation data, especially in the field of CH protection, are of interest, with special focus on the use of multiple sensors and new acquisition modes and data.
