Geological Hazards

AON Benfield did a study in 2010 to assess the risk of future earthquakes in Cape Town. They used data from historical earthquakes around the area between 1620 and 2006 and calculated the average return periods for magnitudes between 3.0 and 6.87, the results of which are shown in Figure 1. The figure below shows that (for example) an earthquake with a magnitude of 6.0 and larger would be expected to occur every 300 years. The predicted upper limit earthquake for the Cape Town area is 6.87.

  1. Good day

    I visited a client today to check and clear geopathic stress from her house. I picked up a tectonic disturbance that happened 7 Months 1 week and 4 days ago (today is the 3rd of August 2020). Reading at 2.2 magnitude.

    Can anyone verify a disturbance around the Melkbosstrand, Western Cape area around that time?
