Earthquake and Tsunami Effects

To repair lifeline systems, especially transportation systems, immediately after the seismic disaster, is very important for the whole restoration process. This paper presents and evaluates the optimum restoration process for damaged transportation systems. The theoretical optimum restoration process is calculated by using the avarage running time of all cars in the transportation network. And the procedure is applyed to the real network system of Izu-peninsula, which was damaged by Izu-Ohshima-kinkai earthquake (1978). The relationship between the characteristics of the roads and the proposed optimum restoration process is also analyzed, using Hayashi's quantification scaling (type 2).
