Johannesburg - An earth tremor measuring four on the Richter scale was recorded in Johannesburg on Monday, the Council for Geoscience said.
Manager of the seismology unit Michelle Grobbelaar described the tremor as "quite a big guy".
The preliminary analysis indicated the epicentre was near the University of Johannesburg just before 10:00.
'Strong'
Tshepo Motlhale, divisional chief for disaster risk management, said the tremor didn't last for more than six seconds.
"We have not received any reports of damage or injury and are consulting with other regions in Johannesburg," he told News24.
Motlhale said he experienced the "strong" tremor while he was in his office.
One Twitter user said: "There was a tremor in JHB about 20mins ago. Building shook for about a minute. I'm still shaking".
Another tweeted: "Oh, so the tremor thing happened all over Joburg? Lol I thought it was just because of the construction in our office park".
Quakes, or tremors, are the result of a stress build-up in the earth's crust. When the stress becomes too great, it is released in the form of a quake, usually on a geological fault line.
Grobbelaar said previously that after an earthquake, it was a rule of thumb that another tremor of similar magnitude could often be expected in the same region, but seismologists could not predict when this would happen.
