Relationship between citizens' risk perceptions formed by disaster information and migration decision-making: Evidence from Japan

Abstract

This study approached the problem of how disaster-related information from various media leads to citizens recognizing risk, and how this affects migration decision-making. A web questionnaire was administered in seven areas that are at risk of being affected by the Nankai megathrust earthquake. The results revealed that those who considered changing their lives in response to this risk are as follows: Young people living on the Pacific coast of Shikoku Island, low-income earners, people who have had extensive experience of earthquake damage, and people who assume that earthquakes are high risk and cause a large amount of damage.
