SMA 1 Waveform Analysis

Since the Sand Point station was at an SH node, the vertical and horizontal components were combined to obtain the incident SV pulse shape by using the free surface transformation

usv(t) = $\displaystyle {\frac{{\cos 2j}}{{2 \cos j}}}$ux(t) + sin juz(t) (1)
Here j is the angle of incidence of the S save, and ux(t) is the horizontal component (positive downward), shown in Figure 2. Fig. 2
