A magnitude 4 earthquake struck South Africa's economic capital of Johannesburg on Monday morning, the Council for Geoscience said. The earthquake occurred before 10:00 a.m. local time, with a preliminary analysis detecting the center of the shock near the University of Johannesburg, said the Council for Geoscience. "We have not received any report of damage or injuries related to the tremor one hour following the earthquake," the city's Emergency Management Services (EMS) said. Many residents felt slight vibrations as the tremor occurred in Johannesburg. "Yes, I can feel it, but (it was) just a little bit," Vicky, a resident in Johannesburg, told Xinhua. Some people felt a strong move of the ground, and some people did not even notice it happened. The tweeters of the City of Johannesburg and Weather SA both confirmed the earthquake. The first recorded damage-causing earthquake in South Africa took place in the small town of Koffiefontein in the central province of the Free State on February 20, 1912, measuring magnitude 6.2 on the Richter scale.
