Strong Motion Attenuation Relations: A Ten‐Year Perspective

Research on strong ground‐motion characteristics conducted in the United States within the last 10 years (1974‐1984) forms the basis for a detailed discussion of important factors to be considered when selecting or developing strong‐motion attenuation relations for use in earthquake engineering and seismic hazard studies. While emphasis is placed on the empirical prediction of ground‐motion amplitudes, a brief discussion of procedures is presented that can be used when insufficient strong‐motion data are available to perform an adequate statistical analysis. The discussion is followed by a tabulated summary of selected strong‐motion attenuation relations proposed and developed in the last 10 years (1974‐1984) to acquaint the reader with the types of relationships currently available.
