Tectonic Settings

As you can see from the figure below, Cape Town lies very close to the Milnerton Fault line. This Fault line has caused serious earthquakes before (explained in seismic history) and also has the potential to cause intense earthquakes in the future.

Cape Town lies fairly central in the African plate and so, doesn’t experience much tectonic activity. As you can see in the plate tectonic map below, the African plate is moving away from the Antartic plate in an oceanic divergent plate boundary.
