Three tremors were recorded in Johannesburg on Wednesday night and Thursday morning.
The preliminary data, collected by the SA National Seismograph Network, showed that three tremors were recorded in the space of nine hours.
The first tremor was recorded at 21:24 on Wednesday night in Doornkop. It recorded a magnitude of 3.2.
The Council for Geoscience confirmed the first and largest earthquake, saying the magnitude was around 3.0.
Its spokesperson, Mahlatse Mononela, said a seismic event of this magnitude was generally not anticipated to result in major structural damage.
According to the council's website, a second tremor was recorded 13 minutes later, in Randfontein, measuring a magnitude of 2.7.
Just before 06:00 on Thursday morning, a third tremor was recorded - in Meadowlands. It measured 2.2.
Mononela said eight aftershocks were recorded, but the main one measured 2.3.
The rest had a magnitude of between 0.2 and 0.8.
A spokesperson for Emergency Services, Robert Mulaudzi, confirmed that Wednesday night's first tremor was reportedly felt in most parts of the city.
He said no incidents were reported to the Emergency Call Centre.
