The recent disaster events in South Korea, such as Busan and Gokseong, generated large damage despite disaster warning. This study aimed to determine the configuration factors of disaster warning which influence disaster prevention behavior. Eight factors were empirically derived as core components of disaster warning, such as professionalism, consistency, timeliness, usefulness, accuracy, accessibility, continuity and diversity.
The statistical model was developed for controllability as the dependent variable and risk perception as a mediating parameter, using the survey data from 331 respondents who received a warning message within the past year. The findings are as follows: First, consistency, accessibility and continuity were found as a statistically significant factor influencing controllability. Second, professionalism and accuracy influenced only on risk perception but not on controllability. Third, timeliness, usefulness and diversity failed to affect controllability or risk perception. Fourth, it is found that both risk perception and controllability influenced disaster prevention behavior. The findings of this study would contribute to effective design of disaster warning systems.
