Abstract

Purpose This paper aims to develop a multi-hazard risk assessment method based on probability theory and a set of economic, social and environmental indicators, which considers the increase in hazards when they occur concurrently or consecutively. Design/methodology/approach Disaster risk assessment generally considers the impact and vulnerability of a single hazard to the affected location/object without considering the combination of multiple hazards occurring concurrently or consecutively. However, disasters are often closely related, occurring in combination or at the same time. Probability theory was used to assess multi-hazard, and a matrix method was used to assess the interaction of hazard vulnerabilities. Findings The results of the case study for the Mid-Central Coastal Region show that the proportions of districts at a very high class of multi-hazard, multi-vulnerabilities and multi-hazard risk are 81%, 89% and 82%, respectively. Multi-hazard risk level tends to decrease from North to South and from East to West. A total of 100% of coastal districts are at high to very high multi-hazard risk classes. The research results could assist in the development of disaster risk reduction programs towards sustainable development and support the management to reduce risks caused by multi-hazard. Originality/value The multi-risk assessment method developed in this study is based on published literature, allowing to compare quantitatively multiple risk caused by multi-hazard occurring concurrently or consecutively, in which, a relative increase in hazard and vulnerability is considered. The method includes the assessment of three components of disaster risk including multi-hazard, exposure and multi-vulnerability. Probability and Copula theories were used to assess multi-hazard, and a matrix method was used to assess the interaction intensity of multi-vulnerabilities in the system.

越南中部沿海地区台风、台风降雨和台风后降雨的多灾害风险评估
目的本文旨在开发一种基于概率论和一组经济、社会和环境指标的多灾害风险评估方法,该方法考虑了灾害同时或连续发生时的增加。设计/方法/方法灾害风险评估通常考虑单个危险对受影响地点/物体的影响和脆弱性,而不考虑同时或连续发生的多个危险的组合。然而,灾害往往是密切相关的,同时或同时发生。概率论用于评估多个危险,矩阵法用于评估危险脆弱性的相互作用。调查结果中中部沿海地区的案例研究结果显示,多灾害、多脆弱性和多灾害风险等级极高的地区比例分别为81%、89%和82%。从北到南、从东到西,多灾害风险等级呈下降趋势。共有100%的沿海地区处于高至极高的多灾害风险等级。研究结果有助于制定可持续发展的减少灾害风险计划,并支持管理层减少多灾害造成的风险。独创性/价值本研究开发的多风险评估方法基于已发表的文献,允许对同时或连续发生的多个危害造成的多个风险进行定量比较,其中考虑了危害和脆弱性的相对增加。该方法包括对灾害风险的三个组成部分进行评估,包括多灾害、暴露和多脆弱性。使用概率论和Copula理论评估多个危害,并使用矩阵方法评估系统中多个漏洞的相互作用强度。
