Ashland and G. N. McDonald Empirical correlation between earthquake ground motion amplification and the average shear wave velocity in the upper 30 meters below the ground surface (Vs30) provides the basis of the site classes in the International Building Code. This knowledge allows engineers to estimate site class effects. The report notes Vs30 for previously mapped engineering geologic units in the Salt Lake City metropolitan area. We
