Abstract

The frequency-dependent duration of strong earthquake ground motion, based on the mean-square integrals of motion, has been correlated with the reported Modified Mercalli Intensity at the recording site. Simple relations have been presented which describe the overall trends of computed durations for different levels of Modified Mercalli Intensity and for three classes of site geology.
