This paper presents a methodology for estimating the number of damaged locations of lifeline systems based on seismic monitoring ground motions taking consideration of liquefaction phenomena. The liquefaction area and the number of damage to the lifeline facilities can be synthetically indicated by a personal computer program developed for this purpose. The method is based on the real time observed data of strong ground motions. Osaka Gas Company had been developing the real time damage simulation system by planning to set additional tele-meter seismographs when the Hanshin Great Earthquake occurred. Other lifelines such as electricity, telecommunication, water and sewage systems in quake-hit area had not such a real time damage simulation tool based on observed ground motions. On the other hand, these lifelines have their own damage detection system such as pressure, flow, relay signal, etc.
