The response of lifelines against earthquakes and seismic hazard effects on them are studied in this paper. As lifelines pass through wide areas, it may be affected by many seismic hazards. These hazards are such as ground rupture, fault movement, landslides and large deformation due to liquefaction. Based on the experiences from past earthquakes, damages to the lifelines with attention to damaged parts are classified and illustrated. This classification is based on the damages of body, joints, facilities and serviceability. Since the buried lifelines are filled with some materials with almost same unit weight of soil, their seismic response characteristics are different from buildings or buried foundations. Surrounding soil affects its seismic behavior. These effective factors are ground characteristic, earthquake characteristic and structure condition.
