The project aims to investigate details of the crustal structure crossing the Waterberg fault zone south of the Erongo Mountains in central Namibia. The special aim of our project is a combined near-incidence and wide-angle seismic reflection survey using 35 mobile six-component stations of GFZ Potsdam, each supplied with 6 vertical GEOPHONEs (180 seismic channels) along two 18 km long lines across the Waterberg fault zone. Conventional CDP style seismic processing will be extended by P- and S-wave tomography of the shallow subsurface.
