Description

Ngozi is the second largest crater lake in Africa. It can be found near Tukuyu, a small town in the highland Rungwe District, Mbeya Region, of southern Tanzania in East Africa.

It is part of the Poroto Ridge and part of the caldera rim is the highest point of the Ridge and mostly composed from trachytic and phonolitic lavas.

The walls of the caldera are forested, with the exception of segments scoured by landslides and high cliffs that inhibit access to the water.

The caldera itself is not subjected to hydrothermal activity, but large subaqueous CO2 emissions and local legends of the killing power of the lake indicate a danger of limnic eruptions.

The lake floor according to echosounding is flat and has no terraces.
