The epicenter of the historic quake on Tuesday afternoon was located just west of the city of Natal in western South Africa, and the epicenter is located at a fault zone of about 50 kilometers (30 miles) long and 35 kilometers (22 miles) wide.
The magnitude of the quake was 7.1.
The quake, which struck at 2:47 p.m.
PT (0:47 a.m., Eastern Standard Time), was the largest recorded in South Africa in more than a century, with damage estimated at more than $6 billion.
The epicentre of the 7.2-magnitude quake was at the eastern end of the Natal Plateau, which is home to some of the world’s most populated cities and is thought to be a keystone in the continent’s crust.
According to the U.N. Office for Disaster Risk Reduction (UNODR), the epicentres of a number of earthquakes in the region over the past two decades are likely to have been related to geological faults.
But there is no specific information available about where the epicents originated or how large they were.
The 7.3-mag magnitude quake that struck in the town of Mbarbo, about 60 kilometers (37 miles) west of Ntibiso, on Tuesday morning was also recorded in the area.
A small earthquake at around 1:45 p.c. on Thursday caused widespread damage in the province of South Africa’s Eastern Cape province.
It was not immediately clear what triggered the damage in that case.
South Africa is on edge because of the ongoing civil unrest that has gripped the country.
The unrest, sparked by the death of a police officer, has sparked a massive national response that has so far left more than 3,000 people dead.
In neighboring Zimbabwe, which was hit by a 3.6-mig earthquake in 2009, more than 400 people were killed in the quake and many more injured.
The country is now on edge after a series of deadly explosions in recent weeks, with at least two more explosions in the capital, Harare, on Wednesday night.
