These difficulties concern in particular to the ability to adequately manage the financial and technical resources available and to identify the intervention priorities (structural and non-structural) throughout the entire emergency cycle. For a correct management, the priority is to quantify and localize, through simulations, the probable damages and to evaluate in terms of cost-benefits the possible alternative mitigation scenarios, technical emergency management and reconstruction actions (Baxter et al. , 2008; Zuccaro and De Gregorio, 2019). In this framework, the project CEASER II (ComplementaryAnalyses for Emergency planning based on Seismic Risks impact evaluations) has been developed with the aim to support the decision makers in the seismic emergency planning. CEASER II project is funded by Agency for the Territorial Cohesion, Managing Authority for the program Governance and Institutional Capacity 2014/2020, concerning the financing of interventions aimed at transferring, evolving and disseminating best practices through the PA 2020 Open Community. The core of the CAESAR II tool is represented by the production of on-demand ‘Seismic Impact scenarios’ (Fig. 1), according to the requests of the end-users in terms of hazard intensities (constituted by PGA furnished by INGV in function of return period) and relevant elements at risk to be considered in the area object of the simulation (Cacace et al. , 2018). The output of the model includes information on expected damage thresholds for buildings (fromD0-no damage to D5-total collapse) and population (deads, injured and homeless, Zuccaro and Cacace 2011). Impact scenarios can be customized based on the territorial detail requested (municipal scale or territorial grid up to 250x250m), data availability and specific needs (Perelli Fig. 1 - CAESAR II tool.
