The damage spreads society and economic function, possibly lead to enormous social loss. For mitigating such damage, it is necessary to understand the structure of interdependency, then planning suitable damage propagation prevention and restoration strategies. However, there has been insufficient research for interdependency among today's urban infrastructures. In this study, the effect of interdependency among critical infrastructures during earthquake disaster is analyzed qualitatively and quantitatively. First, interdependency among critical infrastructures such as electric power, waterworks, gas, transportation, telecommunication, finance, medical services, administrative services, etc. is investigated from past disasters, sorted out as matrices and analyzed by influence diagrams. Next, a propagation model is developed using interdependency structure matrices. Then, the influence of the interdependency is surveyed quantitatively through a case study of an anticipated earthquake disaster in the Tokyo metropolitan area. The results show that almost all the infrastructures are interdependent, and electric power, telecommunications, and highway systems have a greater influence on other infrastructures.
