Fundamental study on development of practical tsunami evacuation simulation system for voluntary disaster preventing organizations

Abstract

Huge marine earthquakes, like the Nankai earthquake which is predicted to occur within the next 50 years near Shikoku island, cause tsunami. Though emergency evacuation drills are very important to find the problems of actual evacuation and make people aware of a sense of crisis, it is difficult to perform such drills with all inhabitants present. In this study, we developed a practical tsunami evacuation simulation system for voluntary disaster preventing organizations as an alternative tool of such drills. In this system, a multi-agent simulation model in which walking ability of each inhabitant can be considered is represented by Petri net. We applied the system to evacuation simulations for Tsunomine area in Anan City which is one of the highest risk tsunami area and found that this system was practical for voluntary disaster preventing organizations.
