Comparison between synthetic waveforms from the quasi-Cartesian (red) and the Cartesian (green) FDTDs at all stations in the target area shown in the left panel of Fig. 8. Upper, middle, and lower panels show the waveforms in the radial, transverse, and vertical components, respectively. These waveforms are set along to the epicentral distances. The amplitude of each trace has been multiplied by the epicentral distance. Each trace has been bandpass-filtered in the period range 10–20 s
