The second part of a seismic risk assessment study for the Iranian city of Isfahan is presented, focusing on the description of the hazard, the risk analysis, and the discussion of the results. This study utilizes the building exposure model, the fragility and the vulnerability curves illustrated in the companion paper. The earthquake occurrence source model adopted is based on the EMME14 hazard study. The site effects accounting for the soil nonlinear behavior are modeled by means of a Vs₃₀ map derived from the topographical slope. The validity of this map is tested based on the local surface geology and geotechnical reports. The probabilistic seismic hazard maps for different return periods that account for site effects are generated and compared with the design spectra mandated by the Iranian national seismic design code. In addition, direct seismic monetary and human losses are estimated for two earthquake scenarios and also for 100- and 475-year return periods. We show loss maps and loss curves, offering insights on the most vulnerable building classes and the spatial distribution of the estimated losses. The results provide a basis for pre- and post-disaster emergency planning, for global and local urban planning, as well as for conceiving adequate risk mitigation strategies including devising fair earthquake insurance policies. This study may also serve as a blueprint for carrying out similar work in other urban areas of the Middle East.

介绍了针对伊朗伊斯法罕市的地震风险评估研究的第二部分，重点是对灾害的描述，风险分析以及对结果的讨论。这项研究利用了建筑物暴露模型，脆弱性和脆弱性曲线，如随附文件所示。所采用的地震发生源模型基于EMME14危害研究。利用Vs ₃₀对解释土壤非线性行为的场地效应进行建模从地形坡度得出的地图。该地图的有效性根据当地地表地质和岩土工程报告进行了测试。生成了考虑场地影响的不同返回期的概率地震灾害图，并将其与伊朗国家地震设计规范规定的设计频谱进行了比较。此外，针对两种地震情景以及100年和475年的回归期，估计了直接的地震金钱和人员损失。我们显示了损耗图和损耗曲线，提供了有关最脆弱建筑类别和估算损耗的空间分布的见解。结果为灾前和灾后应急计划，全球和地方城市规划，以及构想适当的风险缓解策略（包括制定公平的地震保险政策）奠定了基础。
