Abstract
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.Keywords
