Exploring the relationship between risk perception and public disaster mitigation behavior in geological hazard emergency management: a research study in Wenchuan county

Abstract

Modern disaster emergency management emphasizes the collaborative participation of multiple parties. Exploring the relationship between risk perception and mitigation behaviors of the public is essential to develop the effectiveness of public disaster reduction and improve the performance of emergency management. Based on risk perception theory, a research framework on the relationship between risk perception and mitigation behaviors was constructed by selecting two phases of emergency management: pre-disaster preparation and mid-disaster emergency response. The results showed that self-efficacy positively influenced the pre-disaster mitigation behaviors and emergency evacuation behavior. Perceived severity only positively influenced the emergency evacuation behavior in mid-disaster. Additionally, pre-disaster evacuation drills positively influenced the emergency evacuation behavior and the behavior of asking for help from government departments in mid-disaster. The results indicate that pre-disaster mitigation behaviors can have a significant impact on mid-disaster behaviors only if pre-disaster mitigation behaviors provide clear guidance for the emergency phase of the disaster. Therefore, pre-disaster mitigation activities should be carried out strategically with the aim of improving the public’s emergency self-help capabilities in disasters, which provides theoretical and practical guidance for improving the effectiveness of public disaster mitigation and improving the government’s disaster emergency management system.
