図1. 水平位置\((x,y)=(200,0)\)における\(x\)成分の変位波形。 実線はwaterPMLコマンドの結果であり、(0,0,-505)の位置にソースを置いたときの 地表下5 m(赤)、15 m(水色)、25 m(紫)、35 m(茶色)の計算結果を示す。 点線は波数積分法による地表での変位を示しており、 緑はソースを(0,0,-500)に置いた場合の結果、 青はソースを(0,0,-510)に置いた場合の結果である。 Fig. 1. Displacement waveforms (\(x\)-component) at a horizontal location \((x,y)=(200,0)\). Solid lines show the results from the waterPML command, where the source is located at (0,0,-505) and the station is located at 5 m (red), 15 m (light blue), 25 m (cyan), and 35 m (brown) below the ground surface. Dotted lines show the results from the discrete wavenumber method, where the station is located at the ground surface and the source is located at (0,0,-500) and (0,0,-510) in cases of the green and blue lines, respectively. |
