Moho Depth And Crüst-Mantle Velocity Contrast Determinations For South Africa From Teleseismic P-Wave Spectral Ratios

Teleseismic events, recorded on long period or broadband seismometers at three component stations, m y be used to model crustal and upper mantle ]layering beneath the stations. The<br>method used in this study is referred to as the spectral ratio or crustal transfer ratio technique (Phinney, 1964), this involves the analysis of the ratios of the Fourier spectra of the vertical and radial components of the P-wave.
