DIG (Disaster Imagination Game) is known as one of the risk communication methods in Japan. The participants who live in the same area surround a map of the area and discuss the disaster information such as the evacuation routes and the dangers that may lie around. They try to find not only the hazards but also the useful information like the location of the shelter. The detected information is illustrated in the map with pens and seals to visualize the risk and help. Thus the information in the area is shared with the participants. In this study, the new developments are proposed in which the serial video captured by MMS (Mobile Mapping System) is used as well as the map. The combination of the map and the serial video helps to detect the hazards. Moreover, the hazards detected in the workshop are illustrated not only on the map but also in the serial video. The effectiveness of the proposed system is discussed through the application to the practice of DIG.
