Kariba earthquakes
As Lake Kariba filled, the region began to shake, with a swarm of earthquakes peaking in 1963; Tonga tradition says it is Nyami Nyami trying to reach his wife.

The account
The reservoir was one of the largest in the world and the tremors became a classic case in the study of earthquakes set off by dams.
The sceptical view
Geologists explain the shocks as reservoir-induced seismicity caused by the weight of the water and pressure in the rock.
