First, we conduct amultiple-time-window kinematic waveform inversion using strong-motion waveforms,which indicates that a large-slip area located at a depth of 25–30 km in the up-dipdirection from the hypocenter was caused by a rupture propagating upward 6–12 safter its initiation. Moreover, the high-seismicity area of aftershocks did notoverlap with the large-slip area. Subsequently, using the obtained source model anda three-dimensional velocity structure model, we conduct a forward long-period(< 0.5 Hz) ground-motion simulation. The simulation was able to reproduce theoverall ground-motion characteristics in the sedimentary layers of the IshikariLowland.
