4. Conclusions This paper describes the development of the PAPERS platform, providing a comprehensive framework for the exploration and analysis of earthquake scenarios in Italy. The platform combines building and infrastructure exposure models, and state-of-the-art fragility and consequence models for relevant components. It includes a catalogue of historical and hypothetical scenarios and a dedicated national site model. The platform supports both national-scale and building-by-building analyses, and allows users to visualise results interactively through maps, statistics, and charts. The incorporation of the OQ Calculators ensures consistent computation of ground motion fields, damage and losses across all assets, providing aggregated outputs by asset, building type, and region.
