Factors Affecting Behaviors that Precede Evacuation at the Onset of a Heavy Rainstorm in Japan

Abstract

There exist certain behaviors that people tend to do in disaster situations before evacuation. Such behaviors include warning confirmation behavior (for example, seeking information) and family-oriented behavior (for example, contacting one’s family). Identifying factors that affect these behaviors is of particular importance in building a better understanding of why people often fail to respond quickly to evacuation orders. For this purpose, the present study employed some of the established factors affecting evacuation behavior as predictor variables along with the timing of an evacuation order. A total of 518 participants took part in a 12-item online questionnaire survey that contained a hypothetical disaster scenario. The results of ordinal logistic regression analyses revealed that only risk area residence and disaster preparedness were associated with warning confirmation behavior, while gender, age, disaster preparedness, and risk perception had some associations with family-oriented behavior. Also, the participants were not more likely to engage in these behaviors in the morning and the afternoon than the evening in the hypothetical scenario. These findings imply the possibility that people engage in warning confirmation behavior and family-oriented behavior before evacuation regardless of individual characteristics and the circumstances surrounding them.
