We propose empirical envelope models of long period strong motion in a period range of 1 to 10 sec using many JMA 87 type records. We make models for five regions in Japan as a function of epicentral distance and site coefficients which represent site effects due to scattered waves or surface waves. Since the envelope is modeled by average and standard deviation of group delay time in narrow frequency bands, dispersion characteristics of surface waves can be simulated. We show the validity of our models by simulating records of the 1983 Nihonkai-chubu earthquake.
