Attenuation relations of peak ground acceleration and velocity are examined based on records from the 1985 Chile (M 7. 8) and the 1983 Nihonkai-chubu (M 7. 7) earthquakes for the purpose of predicting intensities of strong-motion during large earthquakes in subduction zone. The relations obtained from the Chilean records show that the effects of site geology and source directivity are significant. The relations from the Chilean records are consistent with the Japanese records when the effects of site amplification on the Japanese records are removed. The comparison of the relations with those of previous studies shows that the attenuation relations derived from U. S. data are different from those for these two earthquakes.
