In this study, the existing research on corruption in the field of disaster management discusses the effects of increased risk from disasters on corruption and the effects of corruption on disasters from a one-way perspective, respectively. It also starts from the awareness of the lack of discussion on disaster vulnerability in the impact of corruption on disasters. Based on the necessity of this study, the cyclical relationship between them was empirically analyzed by verifying the mediating effect of corruption on the effect of increased risk from disasters on disaster vulnerability. To this end, the risks of natural disasters classified into earthquake, flood, tsunami, typhoon, and drought for 164 countries out of 195 countries in the world, and the risks from conflict and violence, were composed of human disasters, By measuring the degree of corruption, the relationship between variables was verified using multiple regression analysis to verify the mediating effect. As a result of the analysis, the increase in risk due to the occurrence of a disaster had a significant effect on weakening the vulnerability to disaster, and it was confirmed that the occurrence of a disaster was a factor inducing corruption. Therefore, when considering the cyclical relationship between risk from disasters, disaster vulnerability, and corruption, this study suggests that a one-way perspective on the relationship between disasters, corruption, and disaster vulnerability can mutually influence from a cyclical perspective. It emphasizes the need for an anti-corruption strategy that can secure accountability and transparency at the domestic as well as international level to reduce corruption in the field of disaster management.
