The 2005 Lake Tanganyika earthquake occurred at 14:19:56 local time on 5 December along the East African Rift. This event occurred on a normal fault and had a moment magnitude of 6.8. The fault break initiated at a depth of 22 kilometers (14 mi).

Early reports indicated that the heaviest damage was sustained by the eastern provinces of the Democratic Republic of the Congo (DRC), a region already ravaged by extensive war and extreme poverty. The area houses tens of thousands of refugees displaced by conflicts, such as the Second Congo War and the Burundian Civil War, that have plagued the African Great Lakes in the 1990s and 2000s.

Dozens of houses collapsed in the DRC city of Kalemie.[3] Michel Bonnardeaux, a UN spokesman, said that most of the casualties were caused by falling zinc or steel roofs. The cost to rebuild the whole damage was 1.5 million dollars.

Depending on several factors including soil types, prevalent construction techniques and the acceleration from the earthquake itself, earthquakes with magnitudes in the 6–7 range may or may not cause wide spread damage. In East Africa such seismic events can wreak havoc. The quake was centred roughly below Lake Tanganyika and – in addition to the DRC, where the most widespread damage has been reported – it was felt in Burundi, Tanzania, Rwanda, and as far away as the coastal city of Mombasa in Kenya.[4][5]

The tremor was felt in places as far as Luanda, Angola, where it was felt for around 20 seconds, enough to send people running in panic in search of a shelter. No damage was reported there.
