GFZ German research centre for geo sciences


Omaruru Geophysical Experiment - 1999

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. The seismic measurements will be accompanied by high-resolution magneto-telluric measurements. The resulting detailed velocity/conductivity-depth cross sections will allow the detailed localization of the fault zone and the detailed structure of the surrounding upper crust down to a depth of 10-15 km.
