... 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...

... surface rupture, with at least 2 m of vertical geomorphic offset, has been recorded along the Kango Fault over a lateral distance of at least 84 km, from near the town of De Rust, east of Oudtshoorn, towards the western end of the Baviaanskloof in the Eastern Cape. Although the Kango Fault scarp...

... 5e sea-level high stand, see Roberts and Berger, 1997 ). Extent of neotectonic fault reactivation: Post-Pliocene, possibly Quaternary, surface faulting occurred on the Namibian coastal plain ( White et al., 2009 ), and in the Baviaanskloof mountain range along the South Coast of the South...

... as inferred faults, are here re-interpreted as zones of closely spaced jointing (shatter zones), that show little to no recognisable displacement. The 40 km long, northwest-southeast trending Cape St. Francis fault occurring offshore within 17.5 km of Thyspunt does not continue onshore within the study area...

... of historic and small-scale current seismic activity along several faults in the region, including the Kango-Baviaanskloof-Coega and Kouge-Gamtoos fault sections, and possibly the Zuurberg fault to the north ( Goedhart et al., 2011 ). A recent GPS station set up east-southeast of Willowmore (on the Willowmore...

... are thinly-bedded and predominantly arenaceous, whereas those of the upper Witteberg Group show variation in bed thickness, lithological composition and proportion of arenaceous to argillaceous material. East-southeast striking thrust faults are commonly developed throughout the study area, and have...

...R.E. Diamond; C. Harris Abstract The Table Mountain Group is a folded, faulted, quartzite-dominated sedimentary sequence, metamorphosed to lower greenschist facies, that forms steep mountains dominating the topography of the Western Cape and causing orographic rainfall in an otherwise semi-arid...

..., particularly seismogenic faults, for the Thyspunt PSHA. Given the evidence for reactivation of a portion of the Kango Fault during the Quaternary ( Goedhart and Booth 2009 ), other faults within the Ceres, Kango, Baviaanskloof, Coega (CKBC) fault system and related Kouga fault zone that lie at closer...

The seismically active Ceres-Kango-Baviaanskloof-Coega fault system is the most extensive on-land normal fault feature ( Figure 1b ), and is currently the subject of a study on Neotectonic activity and determination...

These exceptionally long, subparallel fault arrays exploit pre-existing weaknesses in the Cape Fold Belt (Fouché et al., 1993; Paton, 2006). Abbreviations: E = Enon; B = Bredasdorp; G = George; K = Kirkwood; M = Mossel Bay; O...

... the practicality of logging smaller cliffs. Inland exposure is minimal and where material is exposed, thick lichen growth and heavy weathering prevent determination of the large-scale, 3D architecture of sandstone bodies. Joints and faults in the Port Stephens area are common, the latter offset strata by 10 m...

... ). Within the study area, the Table Mountain Group bedrock comprises five sedimentary formations: the Peninsula, Cedarberg, Goudini, Skurweberg and Baviaanskloof Formations ( Figure 1 and Table 1 ). Inadequate exposure prevented differentiation of the predominantly argillaceous Bokkeveld Group ( Figure 1...
