Abstract: A review was made of commonly used correlations between earthquake intensity and peak ground motion. The most recently available basic data were reexamined for this purpose. While curves proposed by other researchers were found to provide the best mean values, the data have such a large spread that mean relationships have questionable value for seismic design. Instead of using mean relationships, it is proposed to enter plots of basic data at levels that are consistent with safety requirements of a project and to generate appropriate parameters for velocity, acceleration, and displacement. In addition, a useful differentiation of acceleration data was found by separating the near field from the far field.
