A magnitude 6.5 earthquake struck nearly 250km north-north-west of the Botswana capital Gaborone overnight, at depth of 12km, the United States Geological Survey said.
Tremors were also felt in neighbouring South Africa.
“We certainly felt it here in central Gaborone,” Jeff Ramsay, Botswana’s chief government spokesman, said.
“I’m not aware of damage yet, it is too early to say. The buildings here in the enclave certainly were trembling.
“I’m not sure where the epicentre was yet and that could be critical. I wouldn’t be surprised if some place there was some type of damage.”
The USGS revised the depth of the quake from 35km. Reuters
