In the 1995 Kobe Earthquake disaster, the water supply networks in the Kobe area experienced severe damage. And, in the disaster emergency response and restoration process of these lifeline facilities, it has been reported that damage to water supply networks have interrelationships effect to the damage in different type of lifelines, such as sewerage, roads, railroads, telephones, communication systems, electric power and gas. Even now, about 30 years after the 1995 Kobe Earthquake disaster, it is easy to imagine that similar phenomenon will occur in case of a large earthquake disaster. The Lifeline Network Kansai (LiNK), which consists of lifeline related organizations and researchers in the Kansai region, examined the past damage and the current installed countermeasures, and the possible interrelationship effect of various types of lifeline networks.
