Abstract This research implements a visualization and analysis system for historical disaster records. This system consists of a storage system and a presentation system for saving and visualizing the disaster information, respectively. In an evaluation experiment, we assessed the operability, readability, necessity, functionality, effectiveness, and applicability of the visualization and analysis system in accessing and visualizing disaster records. The system was evaluated by 18 local government staff. The evaluation was rated highly in many items, but several functionalities, such as “strengthen system cooperation with external applications”, “enhance the stored disaster information”, “enhance the visualization information”, and “cooperate with a map of social media information”, will be introduced and/or extended in future work. Keywords Disaster information · Visualization · Disaster response · Social media
1 Introduction In recent years, information sharing through social media has attracted attention in the disaster management arena, as information can be gathered and disseminated at the time of the disaster (The Fire and Disaster Management Agency 2012). At the time of the Great East Japan Earthquake, fewer restrictions were imposed on packet communications and Internet line communications than on speech lines. Because rescue cases triggered by social media information have also been reported, the national and local governments in Japan have recognized the importance of collecting and transmitting information through social media, and are promoting information dissemination through these media (Cabinet Secretariat 2011). Although the transmitted information contains much erroneous and hoax information, disaster countermeasures using big data on social media have become increasingly important in recent years. Local governments’

disaster response is divided into several stages. The Basic Plan for Emergency Preparedness, formulated by the government’s Central Disaster Management Council, has defined four broad classes of disaster response: “disaster prevention”, “emergency disaster control measures”, “disaster recovery”, and “disaster reconstruction”. These generic classes are reflected in the local disaster prevention plan formulated by local governments. In this research, these three disaster responses are termed the “disaster response phase”.
