ries. It should be noted that the data tables of spectral ratio generally refer to horizontal spectra only. It was found that the spectral ratios for vertical motions in the data sets were essentially the same as those of the corresponding horizontal ratios. In Table 1, the spectral ratios for the gross bin averages for EUS Rock sites are listed for spectral ratios of 2% to 10% damping. Similarly, Tables 2 through 4 provide the spectral ratios for the gross bin averages for the CEUS-Soil, WUS-Rock, and WUS-Soil categories, of 2% to 10% damping. REFERENCES 1.
