Abstract
In the Great East Japan Earthquake, according to the tsunami damage which far exceeds the assumption before an earthquake disaster, the government building which should be a base corresponding to a disaster flowed out, and it was late for restoration and revival of the area. As a result, residents emigrate to other areas and revival of the community has become a difficult situation. Based on these teachings, in order for an overall community to enable early restoration and revival at the worst situation, an organization, a community, and a governmental agency are required for improvement in disaster prevention power in advance supposing the worst situation that the area loses.
In this research, paying attention to a local community, improvement in the disaster prevention power of a local community is considered, and also the local continuation at the time of a large-scale wide area disaster is considered. Disaster prevention and disaster reduction power of a community are quantified using four indices, robustness, redundancy, resourcefulness, and rapidity, and it evaluates as community resilience. Resilience evaluation of the area which has used the index is performed. And the decision technique of the community continuous plan supposing the time of a large-scale wide area disaster is proposed.
