South Africa is not a particularly earthquake-prone country – compared to the likes of China, Iran or Japan – but it does have the unique distinction in that the majority of its seismic activity is caused by deep level mining.
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.
Why are earthquakes rare in South Africa?
Seismic activity in South Africa
What we do know is that large seismic events – or earthquakes – are rare in South Africa. This is because the country is positioned on the interior of a tectonic plate, a relatively rigid area that’s more stable compared with other plate boundaries.
Are there fault lines in South Africa?
We do not have major fault lines. Specifically, Southern Africa is on a very stable faultline. This means our risk for earthquakes and tsunamis are very low. While there is always some seismic risk, we don’t believe there is a real threat for a mega earthquake of seven or more on the Richter scale in the Western Cape.
When last did South Africa have a earthquake?

Is South Africa prone to natural disasters?
Natural disasters in South Africa happen almost every year, and the common ones are earthquakes, floods, and drought. The government should, therefore, implement measures to help citizens survive such disasters since most of them occur without warning.
What is the impact of earthquakes on South Africa?
The effects produced by earthquakes including ground shaking, landslides and rockfalls cause damage to property and loss of life. On a global scale, South Africa is considered a stable region, because it is located away from boundaries between tectonic plates.
Has there ever been a tsunami in South Africa?
In South Africa, there is a significant lack of recorded information on tsunamis that have affected the country and, currently, only five events have been identified as tsunamis (Table 1). The most recent event, attributed to the 2004 mega-transoceanic tsunami, affected parts of the eastern coast of Africa.

The fault runs in a south-easterly direction from about eight kilometres offshore of the Koeberg Nuclear Power station , beneath the Milnerton area and across the Cape Flats and forms the centre of the earthquake belt in Cape Town.
