In this paper, an evaluation of the variation of earthquake ground motions with a focus on site amplification factors based on spectral analysis is presented. By using strong motion record obtained at six sites in Japan, probability distributions of site amplification factors were shown. The relations between standard deviations of site amplification factors and distances between the sites were studied. The variations of representative values of earthquake ground motions based on the variations of site amplification factors were discussed by using probabilistic seismic hazard analysis with focus on Fourier amplitude and group delay time. The distributions of peak ground accelerations and peak ground velocities were shown. It is suggested that design earthquake ground motions considering the average site amplification factors may lead the engineering design on the dangerous side.

A statistically based microzonation tool for delineating zones within a region most susceptible to strong spectral amplification of earthquake accelerations in the 2 to 4 Hertz range is introduced using detailed Modified Mercalli Intensity (MMI) surveys and surface geology. A rationale for the research method is discussed using four arguments: the Fourier spectral analysis of earthquake ground motions and the spectral response method; an empirical versus a theoretical justification, low cost, and a consideration for previous research into the topic specific to the area of the case study chosen.
