In recent years the International Atomic Energy Agency (IAEA) has been closely following and supporting the use of physics-based rupture models for ground motion prediction (e.g. IAEA Safety Standards Series No. SSG–9 and Safety Report Series No. 85) as well as for fault displacement prediction (IAEA-TECDOC , in preparation), respectively for applications in Seismic Hazard Analysis (SHA) and Fault Displacement Hazard Analysis (FDHA) for nuclear installations. Further strengthening of this effort and dissemination in practices for SHA, FDHA and engineering issues have been done through different international working group activities, being the most outstanding two international workshops on Best Practices in Physics-based Fault Rupture Models for Seismic Hazard Assessment of Nuclear Installations (BestPSHANI) in 2015 and 2018. A PAGEOPH topical volume for the BestPSHANI 2015 was published in Dalguer et al. (Pure Appl Geophys 174:3325–3329, 2017). Now, in this PAGEOPH topical volume we collect several articles from the BestPSHANI 2018 workshop as well as several new contributions. The issue also covers further topics on the assessments of engineering issues that rely on ground motion estimates for the evaluation of structures oriented to full seismic risk analysis. A total of twenty-nine papers have been selected covering topics ranging from the seismological aspects of earthquake source studies, ground motion and fault displacement modeling to the engineering application of simulated ground motion for the analysis of soil structure interaction, structural response and fragility curve analysis for the quantification of seismic vulnerability of structures and their seismic performance. Collectively, the seismological papers discuss several current issues of source characterization and ground motion prediction for SHA, highlighting the usefulness of physics-based models for future applications in practice. The engineering papers describe methodologies to develop integral models from source-to-structures that consider the developments of synthetic seismograms as input for structural response and fragility curves estimation for seismic vulnerability assessment. Therefore, this issue contents advanced seismological and engineering resources that might be useful to scientists, engineers, students and practitioners involved in all aspects of SHA, FDHA and vulnerability analysis of engineering structures for seismic risk.

用于核装置地震危险评估的基于物理的故障破裂模型的最佳实践：全面地震风险分析的问题和挑战

近年来，国际原子能机构 (IAEA) 一直密切关注并支持使用基于物理的破裂模型进行地震动预测（例如 IAEA 安全标准系列第 SSG-9 号和安全报告系列第 85 号）至于断层位移预测（IAEA-TECDOC，准备中），分别用于核装置的地震危害分析（SHA）和断层位移危害分析（FDHA）。通过不同的国际工作组活动，进一步加强了这一努力并传播了 SHA、FDHA 和工程问题的实践，这是最杰出的两个关于基于物理的故障破裂模型核装置地震危害评估最佳实践的国际研讨会(BestPSHANI) 在 2015 和 2018 年。2015 年 BestPSHANI 的 PAGEOPH 专题卷发表于 Dalguer 等人。(Pure Appl Geophys 174:3325–3329, 2017)。现在，在本 PAGEOPH 主题卷中，我们收集了来自 BestPSHANI 2018 研讨会的多篇文章以及一些新的贡献。本期还涵盖了关于工程问题评估的更多主题，这些问题依赖于地震动估计来评估面向全面地震风险分析的结构。总共选择了 29 篇论文，涵盖的主题范围从地震源研究的地震学、地震动和断层位移建模到模拟地震动在土壤结构相互作用分析中的工程应用，用于量化结构的地震脆弱性及其抗震性能的结构响应和易损性曲线分析。总体而言，这些地震学论文讨论了 SHA 震源表征和地面运动预测的几个当前问题，强调了基于物理的模型在未来实践中的应用。工程论文描述了开发从震源到结构的整体模型的方法，这些模型将合成地震图的发展作为地震脆弱性评估的结构响应和脆性曲线估计的输入。因此，本期内容包含可能对参与 SHA 各个方面的科学家、工程师、学生和从业人员有用的高级地震学和工程资源，
