Confirmed impact craters

This list of impact craters in Africa includes all confirmed impact craters as listed in the Earth Impact Database. These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface features.

Name Location Diameter (km) Age (years) Coordinates
Amguid Algeria 0.45 < 100,000
Aorounga Chad 12.6 < 345 million
Aouelloul Mauritania 0.39 3.0 ± 0.3 million
BP Structure Libya 2 < 120 million
Bosumtwi Ghana 10.5 1.07 million
Gweni-Fada Chad 14 < 345 million
Kalkkop South Africa 0.64 0.25 million
Kamil Egypt 0.045 < 2000
Kgagodi Botswana 3.5 < 180 million
Luizi DRC 17 < 575 million
Morokweng South Africa 70 145.0 ± 0.8 million
Oasis Libya 18 < 120 million
Ouarkziz Algeria 3.5 < 70 million
Roter Kamm Namibia 2.5 3.7 ± 0.3 million
Talemzane Algeria 1.75 < 3 million
Tenoumer Mauritania 1.9 21,400 ± 9,700
Tin Bider Algeria 6 < 70 million
Tswaing (was Pretoria Saltpan) South Africa 1.13 0.220 ± 0.052 million
Vredefort South Africa 300 2023 ± 4 million

Unconfirmed impact craters

The following craters are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed. However, entries on the unconfirmed list could still have an impact origin disproven.

Name Location Diameter Age Coordinates
Kebira Gilf Kebir region, Egypt 31 km 100 million
Temimichat [1][2] Mauritania 0.75 km unknown
Wembo-Nyama ring structure[3][4] DR Congo 36–46 km (est.) 60 million
