In order to mitigate the damage caused by serious disasters, it is necessary to improve the disaster prevention literacy of residents. In this study, a disaster risk communication method consisting of risk mapping and timeline development was developed to support residents' proactive disaster prevention activities by accumulating disaster information in a spatio-temporal manner. The risk map provided an understanding of the spatial distribution of disaster risks, and the timeline triggered a chain of self-help and mutual-help actions.
