Earthquakes in Kariba are normally associated with variations in water levels in Lake Kariba since its impoundment in the early 1960s.
Quakes of Magnitude 2.5 or less are normally not felt but occur about 900 000 times in a year but can be recorded by a seismograph while those ranging between 2,5 and 5,4 can be felt and cause minor damage.
However, those of magnitude 7.0 to 7.9 are classified at major earthquakes, causing serious damage to infrastructure, and occur about 20 times in a year.
Great earthquakes, occur once every five to 10 years and have a magnitude of 8.0 or greater, causing destruction of entire communities.
