Second earthquake strikes Southern Africa hours after first
It’s common to experience a second tremor after an earthquake, but it’s very uncommon for the second tremor to be larger than the first one.
The US Geological Society (USGS) reported the occurrence of a second earthquake yesterday (3 April) at about 6pm. The epicentre of the quake was 132km from Moijaba, Botswana.
The earthquake measured a magnitude of 6,5 on the Righter Scale and occurred 29km beneath the Earth’s surface.

It is common to experience tremors after an earthquake. These are called aftershock tremors. However, it is uncommon for aftershocks to be larger than the first earthquake, USGS reports.
If the second tremor is larger than the first, the first tremor is called a foreshock.
It’s common for two earthquakes of more or less the same magnitude to occur in sequence.
While some residents of Krugersdorp were still baffled by the first tremor, others have already started telling stories about the second earthquake.
