Outline of Final Research Achievements

It is pointed out that those who have a high recognition of disaster risk does not always take precautionary actions against natural disasters. This is called disaster risk perception paradox. The existence of a risk perception paradox implies that it is not enough for promoting personal protective actions just to improve risk perception. We analyzed the precautionary evacuation behavior based on the protection motivation theory. Consequently, if coping appraisal is low, it is confirmed that there are instances where personal protective actions are spoiled even if thread appraisal is high. We also verified global and local characteristics of individual mitigation actions to obtain unified view of the resolution of risk perception paradox. Consequently, for the promotion of preparing an emergency bag, it concludes that it is commonly effective to improve a perception of the coping appraisal in response efficacy and cost rather than the threat appraisal about natural disaster.
