Abstract
In order to understand the historical evolution of the Chizu-Ichinose community disaster risk mitigation conflict, The dispute is modeled as a static structure for each of two phases, one from 1985 to 2002, and the other from 2002 to date (2005). The GMCR model (Graph Model for Conflict Resolution) is used to systematically describe the process of changes in the structure of this conflict. Then we focus on the structural change, which is interpreted to have occurred instantaneously between the end of the first phase and the beginning of the second phase. This structural change is qualitatively interpreted as the outcome of the intervening social shocks identified as a natural disaster impact, which may have been compounded by some political shift in the local government. This combined approach is found to be a useful methodology to systematically describe the combined process of both static and dynamic structure of the real conflict focused in this paper.
