Topographic Effects on the Seismic Response of Trapezoidal Canyons Subjected to Obliquely Incident SV Waves

Figure 11

Effect of normalized canyon height on the Fourier amplitude spectrum of (a) horizontal and (b) vertical ground accelerations for configurations with and under vertically and obliquely incident SV waves. The white solid lines and dashed lines represent the locations of the crests and feet of the canyon model, respectively.
