Italian Risk MAps (IRMA) is an innovative IT platform developed by European centre for training and research in earthquake engineering (Eucentre) with funds of the Italian Civil Protection Department, and addressed to the scientific community. IRMA allows data sharing, methods and models aimed to evaluate the seismic risk of Italian residential buildings, in order to comply with the requirements of the “Sendai Framework for Disaster Risk Reduction 2015–2030” (Sendai Framework). IRMA uses OpenQuake, a calculation engine developed as part of the Global Earthquake Model, to evaluate earthquake loss estimation. The user can create and upload different exposure/vulnerability databases as well as different sets of fragility curves on the platform. The hazard used in the platform is the MPS04 hazard model, developed by National Institute of Geophysics and Volcanology that is actually the reference hazard map for the Italian code regulation. IRMA is extremely flexible: by combining the different exposure databases with all the possible sets of fragility curves, the user can produce maps of conditional damage (i.e. the return period is selected) or unconditional damage (i.e. an observation time window is selected). Damage scenarios can also be performed by using shakemaps of seismic events as input. The shakemaps, preloaded in the platform, are those referred to the recent seismic events in Italy. The article describes the context in which IRMA was developed, its features and architecture. IRMA was used in 2018 by DPC to produce the National Risk Assessment, in agreement with EU decision 1313/2013.

意大利风险地图（IRMA）是创新的IT平台，由欧洲地震中心培训中心（Eucentre）开发，并得到了意大利民防局的资助，并面向科学界。IRMA允许旨在评估意大利住宅建筑物地震风险的数据共享，方法和模型，以符合“ 2015-2030年仙台减少灾害风险框架”（仙台框架）的要求。IRMA使用OpenQuake（一种作为全球地震模型的一部分开发的计算引擎）来评估地震损失估算。用户可以在平台上创建和上传不同的暴露/漏洞数据库以及不同的易碎性曲线集。平台中使用的危害是MPS04危害模型，由国家地球物理与火山研究所开发，实际上是意大利法规的参考危害图。IRMA非常灵活：通过将不同的暴露数据库与所有可能的易碎性曲线集组合在一起，用户可以生成有条件损害（即选择返回期）或无条件损害（即选择观察时间窗口）的地图。还可以通过使用地震事件的振动图作为输入来执行破坏方案。预加载在平台中的震动图是指意大利最近发生的地震事件的震动图。本文介绍了IRMA的开发环境，功能和体系结构。根据欧盟第1313/2013号决定，DPC在2018年使用IRMA进行了国家风险评估。
