The spatial variation of seismic ground motions denotes the differences in the seismic time histories at various locations on the ground surface. This book focuses on the spatial variability of the motions that is caused by the propagation of the waveforms from the earthquake source through the earth strata to the ground surface. In recent years, the modeling of the spatial variation of the seismic ground motions and its influence on the response of lifeline systems, such as pipelines, tunnels, bridges and dams, attracted significant interest, and, currently, design codes incorporate its effects in their provisions. The topic is being addressed by the engineering seismology community for the modeling of the spatial variability, the probabilistic engineering community for the simulation of spatially variable seismic time series and the in corporation of spatial variability in random vibration approaches, and the earthquake engineering community for examining its effects on lifeline systems and utilizing it in the design of the structures.
