The affected slope is composed of weak overburden material mostly weathered and fragmented rock overlain by thick sandy insitu soil. During rainfall, water infiltration raised the temporary water level and reduced the shearing strength of the overburden

Past landslides had damaged large cultivated lands (valley portion) that exist just below the road bench.
Nkio–Prasadimdik slide No.4
Nkio–Prasadimdik road section.
1. Construction of strong reinforced retaining wall/gabion wall at the toe of the slide founded on firm substratum.
2. Lined hillside draiNGe should be maintained.

1. Weak slope forming material comprising highly weathered sandstone and insitu soil.
2. Anthropogenic activities: toe cutting of slope. 
3. Development of local hydrostatic pressure and reduction of strength on oversaturation of weak overburden material
