Determinant Factors Affecting Residents' Behavioral Intention of Evacuation during Natural Irrigation Pond Disasters

—A case of Rokujoin-naka, Okayama prefecture—

Abstract

This study clarifies factors determining residents' evacuation intention during irrigation pond disasters. First, an evacuation intention model is constructed, following which a questionnaire investigation is conducted at Rokujoin-naka, Asakuchi city, Okayama prefecture, using the evacuation intention model. The multiple linear regression analysis reveals that the factors strongly influencing evacuation intention are a positive attitude when called to evacuate, the perception that people around oneself also need to evacuate in times of disaster, thinking that one's home will be damaged if the irrigation pond collapse and a positive attitude to evacuate. Therefore, to encourage residents' evacuation intention when the irrigation pond is in danger of collapsing, calling for evacuation, fostering people who urge resident to evacuate and making resident aware of the risks of the irrigation pond collapsing using hazard map, etc. are important.
