Simulations of long-period ground motion in various models. Simulation results of (a) Event a and b Event b. Observed F-net vertical seismograms are represented by bold gray lines. The blue, red, and black lines are simulated vertical seismograms of the JIVSM, JIVSM without sediments, and F-net 1D model, respectively. The physical parameters of sedimentary layers of the JIVSM without sediments were replaced with those of the upper crust (see TableĀ 1). Locations of seismic sources and stations are illustrated in the upper left panel. Plotted focal mechanisms are the optimal solutions of events a and b
