The U.S. Geological Survey, which records earthquakes around the world, recorded a 5.0 magnitude earthquake at 2:38 a.m. local time.

It said the epicenter was 6 kilometers (3.7 miles) from Alberton, a town on the southeastern outskirts of Johannesburg..

There were no immediate reports of casualties or any significant damage. An earthquake of that strength is classified as minor but would be clearly felt and might cause small damage to buildings.

Residents who lives close to the epicenter said the shaking felt like being on a moving train and lasted for about a minute.

Many people in Gauteng province, which includes Johannesburg, said on social media they awoke to find the walls of their homes shaking. Local media published videos showing the moment the quake struck.
