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.
Can a tsunami hit Africa?
The 2004 Indian Ocean earthquake sent a tsunami surging outward from Sumatra, devastating coastlines across Southeast Asia but doing much less damage by the time it reached Africa. Many scientists have since considered the tsunami risk in parts of East Africa to be relatively low.
Is a tsunami possible in Cape Town?
We do not have major fault lines. 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.”

Is Cape Town prone to earthquakes?
Earthquakes are a particularly rare event in Cape Town, but they are not unheard of. That’s because the Mother City rests upon ‘The Milnerton Faultline’. It runs from offshore along the West Coast right past Koeberg, through Milnerton, and into the Cape Flats.
