As flood advances greater, inhabitants have a tendency to perceive a lot of information signaling imminent danger, such as changes of circumferential situation, disaster information, evacuation order and so on. In this study, we take notice of this process, and grasp the effect of information signaling imminent danger on determination process of inhabitants' consciousness and behavior for flood disaster, using the data from a questionnaire survey instancing the case of residents of Koriyama in flood by Typhoon 6 in July 2002. In this examination, we explain the effect and significance of the preliminary information for evacuation behavior and the improvement of inhabitants' perception of inundation potential through the disaster education such as a publication of flood hazard map.
