“…Byerly's review of the travel-time studies (refraction studies) shows that the velocities ascribed to the intermediate layer and the thicknesses given for the intermediate layer vary very widely. The structure inferred for the Eastern Transvaal is in fairly good agreement with that determined by Reich, Schulze & Fortsch (1948) and RothC, Peterschmitt & Stahl(1948) in studies based on the Haslach explosions in the Black Forest region. Work done since 1956 tends to support the view that there is an intermediate layer.…”

Observations of the travel times of waves from Witwatersrand earth tremors along a route in the Eastern Transvaal are reported in this paper. It is considered that the most satisfactory interpretation is that the crust is two-layered. The velocities in the granitic layer are 6.0 and 3-6 km/s for P and S waves respectively. In the intermediate layer the P velocity lies between 6.7 and 7 -2 km/s, and the S velocity between 3.95 and 4-15 km/s. The Pn velocity was found to be 7-96 km/s and the crustal thickness 36.6 km.It was found that Pn arrivals at stations close to sea level were early with respect to the travel-time found for the plateau at a height of about I 750 m.
