In many cases, evacuations during floods are triggered by direct calls by neighbors, while there are also increasing numbers of cases in which daily communication and information transmission during disasters are conducted via message apps within neighborhood associations and communities. In this study, we hypothesize that the presentation of evacuation-induced conversation screens among residents on a messaging application when flooding danger is imminent contributes to the increase individual willingness to evacuate, compared to the presentation of evacuation instructions on a normal screen. Visual analogue scale, which can measure subjective evaluation as continuous variables with interval scale, was used to evaluate the willingness to evacuate. The evacuation instructions were presented as the control group, and other four types of screens, including the neighbors’ conversations and image information, were used as the treatment groups.
