JOHANNESBURG (Reuters) – A 6.1 magnitude earthquake struck offshore from South Africa on Saturday, according to the U.S. Geological Survey (USGS).
Some residents of the southern city of Cape Town posted on Twitter that they had felt the tremor, which the USGS said occurred at around 1710 GMT, at a depth of 10 kilometres and far south of South Africa’s coast.
“Guys, we just felt a tremor in Cape Town. Our house shook, the ground shook and rumbled, there was a faint rumbling sound. It all lasted 5 seconds,” one resident wrote on Twitter.
There were no immediate reports of casualties or damage.
“The 6.2 magnitude event just basically happened a little earlier. Because it was so far away, over 1600 km south of South Africa along the African plate module, it was highly unlikely that we felt that event. We are attributing it to the smaller event that happening just North of Durbanville,” said Dr David Khoza, Executive manager of Applied Geosciences at the Council for Geosciences.
