A huge underwater 'avalanche' off the coast of West Africa kept moving for two days, scientists reveal. The colossal event happened underwater in Congo Canyon, a deep submarine canyon leading away from the mouth of the Congo River, on Africa's west coast. The avalanche broke two seabed telecommunication cables that underpin data traffic to West Africa, causing the internet to slow from Nigeria to South Africa. A turbidity current is a rapid, downhill flow of water caused by increased density due to high amounts of sediment. Congo Canyon is a submarine canyon found at the end of the Congo River in Africa.
