Locations of confirmed impact craters in Africa, maximum ages:
Cenozoic
Mesozoic
Paleozoic
Precambrian

This list of impact structures in Africa includes all 20 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.

Unconfirmed impact structures[edit]

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.

Notes[edit]

1Mahas was anonymously added Jan 2015, but the coordinates do show a convincing impact-like structure.

It appears to me there is also an impact crater several miles in diameter, approximately 40-45 miles to the SE of Tete, Mozambique. But this only based from an aerial inspection from Google Earth and not from any ground inspection or geological verification.
