We extract static displacement Dp and long-period (2-10 s) velocity pulse from strong motion records of crustal earthquakes in Japan and examine them by comparing with those of the 2016 Kumamoto earthquake and previous prediction equations. The period of long-period pulse of four earthquakes with Mw6.6-Mw7.0 is about 3 s, which is consistent to one of previous equations. Prediction of Dp is improved by substituting the relation between seismic moment and rupture area derived in this study using fault models from geodetic data into the equation by Kamai et al. (2014).
