Emergency services department did not report any casualties nor injuries but said that the disaster management teams would remain on standby. Johannesburg emergency services spokeswoman Xolile Khumalo warned residents to "be on alert in case after tremors occur, (as) these tend to be more dangerous than the initial earthquake".

The epicentre of the "relatively long tremor" was at Boksburg, small a town located about 20 kilometres east of Johannesburg, the authorities said. In August 2014, a 5.3 magnitude earthquake hit a gold mining town near Johannesburg.
