Johannesburg – An earth tremor of 2.2 on the Richter scale occurred early on Wednesday morning on Johannesburg’s East Rand, the Council for Geoscience (CGS) said.

“We were alerted to it this [Wednesday] morning. It was in the Boksburg area at about 05:00,” said lead competency manager Michelle Grobbelaar.

“It was about a magnitude of 2.2. It’s very surprising that people felt it. It appears it [the tremor] was quite shallow.”
