Abstract
Italy is a country with high seismic hazard, however since the delay in the seismic classification of the national territory, most of the existing building heritage does not comply with the current technical standards for buildings. The seismic events that have hit different Italian regions in recent years have highlighted the complexity of the challenge for the public bodies both in the emergency management and post-event reconstruction and in the planning of effective risk prevention and mitigation measures to be implemented in ‘peacetime’. These difficulties concern, in particular, the capacity to properly manage the financial and technical resources available and to identify the intervention priorities throughout the entire emergency cycle. For correct management, the priority is to quantify and localize, through simulations, the quantification of probable damages and to evaluate in terms of cost-benefits the possible alternative strategies for mitigation, also taking into account the potential, in terms of cost-effectiveness, of integrated measures for seismic and energy retrofitting. In this framework, the project CAESAR II (Complementary Analyses for Emergency planning based on Seismic Risks impact evaluations) has been developed as a Decision Support System for Public Authorities in charge of developing Disaster Risk Reduction plans, with the possibility of programming mid to long-term investments for public and private properties, as well as defining custom financial support mechanisms and tax incentives.
Highlights
CAESAR II is a decision support tool for local authorities, developed to improve the coordination capacity of the seismic emergency planning and management processes, as well as the allocation of resources intended for risk mitigation on buildings and infrastructures, with the use of cost-benefit and multi-criteria analysis tools
The main objective is that of governance that works in an organic way, systematizing all the actors involved, at all levels, in the implementation of public investment programs to act in a coordinated, more efficient, more effective way and to a better ability to carry out interventions aimed at achieving the expected results
The Italian municipalities with CAESAR II have a new tool at their disposal capable of enabling them to access the most sophisticated technologies to analyze the seismic risk within their territory, with a detail on a neighborhood scale
Summary
Risks impact evaluations) is a tool developed as a decision support system for public authorities involved in the development of seismic disaster risk reduction plans, with the possibility of planning medium and long-term investments, as well as defining customized financial support mechanisms and tax incentives. One of the newcomers is the IRMA (Italian Risk Maps) platform [20], developed by the Department of Italian Civil Protection (DPC) It integrates tools for calculating damage scenarios and risk maps for the Italian territory. The hazard for calculating risk maps is instead preloaded and is the hazard model developed by INGV (National Institute of Geophysics and Volcanology) and adopted at the national level In this framework, the CAESAR II project is born. It is a web-service procedure conceived as a decision support system for public authorities engaged in the development of disaster risk reduction plans It is a web-service tool producing scenario and seismic risk analyses in terms of economic, building and human life losses and evaluating their possible reduction through cost-benefit and multi-criteria analyses to support decisions. The CAESAR II model is illustrated e its application concerning the municipality of Cava de’ Tirreni is shown
