An earthquake monitoring and early warning system for a large-scale city gas network has been developed in the Tokyo Metropolitan area. The monitoring system consists of 356 earthquake sensors. Once an earthquake occurs, values monitored by these sensors will be sent to the supply control center by radio. Then estimation of damage 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 will be conducted. The system will play an important role in mitigating gas-related secondary disasters due to earthquakes.
