Rustenburg - Structural engineers were inspecting the Rustenburg municipal office building following an earthquake on Tuesday, the municipality said.

“The eight-storey building vibrated during the earthquake. The building was evacuated for safety reasons,” said spokesman Thapelo Matebesi.

He said acting municipal manager Marks Rapoo's advice was not to let workers back into the Missionary Mpheni building until it was assessed by engineers.

“The engineers will submit their report to the municipal manager today. Employees will come to work on Wednesday morning and only allowed in once is safe to do so.”

The Council for Geoscience said the earthquake that struck various parts of the country was recorded at a magnitude of 5.5 on the Richter scale.
