Within the 2019–2021 research agreement between the Civil Protection Department (DPC) and the Network of University Laboratories for Earthquake Engineering (ReLUIS), the work package WP4 “Seismic Risk Maps—MARS” is specifically devoted to update the 2018 release of the Italian National Seismic Risk Assessment. To this end, the previously considered models of hazard, exposure and vulnerability will be critically reviewed and updated by taking advantage also from the results deriving from other WPs of the DPC-ReLUIS research project. In the present paper some of the most relevant aspects that are being introduced in the development of the new Italian risk maps have been described and shortly analysed. First, a significant upgrade of the vulnerability model implemented in the new version of the platform used for risk calculation (IRMA) is proposed, where reference to the six EMS-98 classes is made also considering regional vulnerability features. Further, empirical data from observed real damage are integrated with results from numerical simulations (mechanical approach), in particular for reinforced concrete buildings. Finally, some special construction types such as schools, churches and bridges are included in order to provide a more comprehensive view of the national risk.

根据民防部（DPC）与大学地震工程实验室网络（ReLUIS）之间的2019-2021年研究协议，工作包WP4“地震风险图-MARS”专门用于更新2018年版的意大利语国家地震风险评估。为此，还将充分利用DPC-ReLUIS研究项目其他WP的结果，对以前考虑的危害，暴露和脆弱性模型进行严格审查和更新。在本文中，已经描述并简短地分析了在开发新的意大利风险地图时引入的一些最相关的方面。首先，建议对用于风险计算（IRMA）平台的新版本中实现的漏洞模型进行重大升级，在提及六个EMS-98类时，还考虑了区域漏洞特征。此外，观察到的实际破坏的经验数据与数值模拟（机械方法）的结果相结合，特别是对于钢筋混凝土建筑。最后，还包括一些特殊的建筑类型，例如学校，教堂和桥梁，以便更全面地了解国家风险。
