本文提出了一种量化挪威各城市对自然灾害的社会脆弱性的方法。 In the analysis, a large number of variables that each measures a facet of a municipality's susceptibility to a potential hazard are used. Using factor analysis, the information in the variables is reduced to a smaller number of factors and socioeconomic and built environment vulnerability scores for each Norwegian municipality are calculated.社会经济脆弱性指数和建筑环境指数的得分针对每个城市进行了绘制。结果显示，存在明显的区域差异：社会经济脆弱性较高的城市集中在挪威北半部和东南部部分地区。最不受影响的地区是挪威西南部。人口稠密地区的建筑环境脆弱性最高。通过指出脆弱性较高的城市，本文提出的方法是识别在应对大规模事件时可能面临重大挑战的地区的有用工具。例如，研究结果可用于规划针对极端天气事件的缓解措施，由于气候变化，未来这些事件可能会更加频繁和严重。
The article presents a method for quantifying social vulnerability to natural hazards in Norwegian municipalities. In the analysis, a large number of variables that each measures a facet of a municipality's susceptibility to a potential hazard are used. Using factor analysis, the information in the variables is reduced to a smaller number of factors and socioeconomic and built environment vulnerability scores for each Norwegian municipality are calculated. The resulting scores in the Socioeconomic Vulnerability Index and Built Environment Index are mapped for each municipality. The results show that there are pronounced regional differences: municipalities with high socioeconomic vulnerability cluster in the northern half of Norway and parts of the south-east. The least vulnerable region is south-western Norway. Built environment vulnerability is highest in densely populated areas. By indicating municipalities with a high level of vulnerability, the method presented in this article is a useful tool in identifying regions which are likely to face significant challenges in coping with a large-scale event. The results can be used in, for example, planning mitigation efforts against extreme weather events, which are likely to be more frequent and severe in the future due to climate change.
