"A low-grade tremor was registered on the Richter Scale and measured 3.4. The tremor ran 6km deep along the Cango faultline. The Cango Caves have been temporarily closed to assess but no damage has been reported so far anywhere," said Chantel Edwards-Klose, acting chief of media liaison.
"This is an isolated event and the Council of Geoscience (National Science Council of South Africa) is in contact with Eden Disaster Management."
According to reports from residents and comments on social media, tremors were felt in the Bergsig and Genevafontein area, Dormehlsdrift and as far as Wilderness and Langvlei Dunes.
"Earth shaking and furniture rattling in Langvlei Dune. Many residents have reported this," says Jane MacKenzie-Hoskyn in an e-mail.
Sarie Katzke from Wilderness writes on Facebook that her sliding doors "also danced merrily".
