DEVELOPMENT OF CITY GAS NETWORK ALERT SYSTEM BASED ON MONITORED EARTHQUAKE GROUND MOTION

抄録（英）：
A seismic information gathering and network alert (SIGNAL) system for a large-scale city gas network has developed based on extensive earthquake monitoring and GIS. The monitoring system consists of 331 SI-sensors, 5 accelerometers and 20 liquefaction sensors. Once an earthquake occurs, monitored values by these sensors are sent to the network control certer by radio. The emergency operation system is activated as soon as these monitored values are received. Then damage estimation to customers' buildings and pipelines, estimation of the magnitude and hypocenter, evaluation of the response spectrum, and decision analysis whether to shut-off or maintain the supply based on the estimated results are conducted. SIGNAL has started operation recently. This paper introduces SIGNAL and case studies using it.
