Engineers usually require probabilistic expressions of seismic hazard, which require extensive knowledge of earthquake phenomena from geoscientists. The physical causes of the remarkably large degree of predictable variability in earthquake ground motions are explored, and their representation in design ground motions in the spectral and time domains is described. Progress in the understanding and quantification of seismic hazards for application in engineering practice is documented in case histories which date back to early applications of modern theoretical seismology and plate tectonic theory.
