... experienced the well-known 6.3 M Ceres-Tulbagh event of 29 September 1969 (currently South Africa's largest and most damaging earthquake). This latter strike-slip event occurred along the western end of the same Ceres-Kango-Baviaanskloof-Coega (CKBC) fault system, but was not accompanied by significant...

... to be partly controlled by the original depositional environment, namely, near-shore and beach environments. Strata in the study area display a range of fold styles, mostly showing northward vergence. Low angle thrust faults dip south and some thrusts dip north. In general, the orientation of fore-thrusts...
