Cape Town - The Council for Geoscience (CGS) confirmed a light magnitude 3.49 earthquake occurred off the West Coast this week.
This, as the European-Mediterranean Seismological Centre (EMSC) also reported the quake about 76km West of Cape Town at a shallow depth of 10km.
CGS spokesperson, Mahlatse Mononela, confirmed the quake occurred on Wednesday at around 4.14pm.
“The preliminary results show that the earthquake registered a local magnitude of approximately 3.49, as recorded by the South African Seismograph Network (SANSN).
“The epicentre was located approximately 20km west of Dassen Island in the Atlantic Ocean,” Mononela.
The public has been encouraged to record their experience using the available online questionnaire, however, it was expected that the quake was not felt by many people.
