Abstract

The Western Cape is an area of low to<br>intermediate levels of anomalous seismicity, and as<br>a result defined as a relatively low risk seismic<br>hazard area. This assumption has traditionally been<br>based on relatively few macroseismic observations,<br>and the apparent lack of geological evidence<br>supporting neotectonic ground rupture. In this<br>paper we show that geological methods of seismic<br>hazard assessment are unsatisfactory for defining<br>risk assessment in intraplate anorogenic zones, and<br>report on preliminary findings from an ongoing<br>microseismic investigation into the South Western Cape.
