No injuries after Gauteng quake
Johannesburg - No injuries were reported when an earthquake hit Johannesburg in the early hours of Friday morning, paramedics said.
Johannesburg emergency services spokesperson Nana Radebe said they were not called out to help anyone and there were no reports of injuries.
ER24 spokesperson Werner Vermaak said they were on stand-by after the quake struck, but they were also not called out.
The US Geological Survey said on its website that a 4.6 magnitude earthquake occurred 12 kilometres west of Orange Farm, a township south of Johannesburg.
The Council for Geoscience later said the quake was 3.8 magnitude, and not 4.6 as estimated by the US Geological Survey.
"It's the same event. The USGS measurement is done by a machine, and the stations they use are not in as close proximity to the quake as ours, and that's why it's different," council seismology unit manager Michelle Grobbelaar said.
The quake, which happened around 01:00, is the second in South Africa in less than three weeks.
On 5 August, a 31-year-old man was killed in a mining village near Orkney, North West, when the 5.5 magnitude earthquake struck in the region.
At least 34 miners were injured by the earthquake, and more than 600 houses were damaged.
More tremors expected
After the first earthquake, the Council for Geoscience in South Africa said more tremors were expected to hit the country.
Manager of the council's seismology unit Michelle Grobbelaar said more tremors and aftershocks were expected in the coming days.
"More tremors are expected. We can expect one of the same magnitude in future, we just don't know when. We cannot predict."
