Residents of certain parts of Johannesburg including the East Rand woke up to a seismic event of the earth trembling under their feet this Sunday, August 28.

According to Gauteng Weather Services, a 3.1 magnitude tremor was recorded between Brakpan and Springs just before 01:00.

This is in addition to a similar event that was reported to have occurred only more than a week ago, yet to be confirmed by the Council of Geoscience.

According to experts at Volcanic Discovery, some underfoot rumbling was detected in Johannesburg last night, however, the magnitude of the seismic activity does not warrant an earthquake as many would like to believe.

“We are receiving reports of ground-shaking, possibly caused by seismic activity in or near Johannesburg, Gauteng, on August 16, 2022, at approximately 21:29 GMT [23:29 SAST].  The location, magnitude and time mentioned are indicative, based on our best-fit seismic model,” said Volcanic Discovery.

Johannesburg is no stranger to the occasional tremor. As recently as July 17, 2022, a 3.8 on the Richter Scale was recorded in the metropolitan area – which fell just short of the 4.0 threshold needed to declare an actual earthquake.
