Abstract

During 8 or 9 February 2000, after several days and nights of continuous rains, two rockslides occurred in the hills east of Mokolodi village, south-east Botswana. It is estimated that a minimum of 1000 tonnes of water-saturated rockmaterial was displaced through two parallel channels in direction 340� NNW over a distance of maximum 500 metres. Two ridges of colluvium border the scoured out bedrock, the width of the channels in the lower parts of the slope being up to 15 metres. The displaced rock material consists of rocks of the Kanye Volcanic Formation. Since this phenomenon may recur, it seems unwise to use this area for future building sites.
