Are earthquakes common in South Africa?
The Council for Geoscience in South Africa records minor earthquakes, also referred to as tremors, on a daily basis. But rapid urbanisation, an increasing number of seismometers and the popularity of social media may explain why earthquakes appear to occur more frequently.
What caused the earthquake in South Africa?
It caused widespread damage in the towns of Ceres, Tulbagh and Wolseley and led to 12 deaths. The earthquake was a result of strike-slip faulting along a NW-SE trending near vertical fault plane, as shown by the focal mechanism and the distribution of aftershocks.

Can Cape Town have a tsunami?
Specifically, southern Africa is on a very stable fault line. This means our risk for earthquakes and tsunamis is very low. “While there is always some seismic risk, we don’t believe there is a real threat for a mega earthquake of 7 or more on the Richter scale.”
Which country has the most earthquakes in Africa?
Large earthquakes are relatively rare in Africa. Only four earthquakes with M>7 have been recorded since 1900, the largest being a M7. 3 event in Tanzania in 1910. African countries exposed to the highest risk are Morocco and Algeria, and countries that straddle the East African Rift.
Why are there no earthquakes in South Africa?
On a global scale, South Africa is considered a stable region, because it is located away from boundaries between tectonic plates. Therefore its activity rate is lower than in seismically active regions like California or Japan.
