The Hanshin-Awaji Earthquake of January 17, 1995: Performance of Lifelines
MetadataShow full item record
This report describes the damage to lifelines caused by the 1995 Hanshin-Awaji (Kobe) earthquake in Japan. It begins with a summary of the earthquake's seismological characteristics which is followed by separate chapters that focus on the performance of lifelines in the affected region. In order of presentation, individual chapters discuss the damage to: 1) electric power networks; 2) gas delivery systems; 3) hospitals (considered as a system composed of building/architectural components, as well as communication and support systems); 4) telecommunication systems; 5) transportation systems; and 6) water supply systems and wastewater systems. The transportation section includes three subsections: airport facilities, highways and bridges, and underground rapid transit systems. For each lifeline, an overview of the system is given, indicating the owner/operator, the location and extent of the service area, the number of households and industrial/commercial customers served. In addition to descriptions of the individual system, design criteria for the physical components of the individual systems are provided, including a comparison of the differences between the US and Japanese systems. The performance of each lifeline system is discussed with reference to seismic damage, emergency response, service interruption and restoration. (Adapted from authors' abstract).
