The Yelmo debris slide has occurred along the Hunli-Anini road section, due to oversaturation of slope forming material due to rainfall causing local hydrostatic pressure and loss of cohesion on the affected slope.

1. Removal of rock boulders and slided material at critical angle from slope of the slide. 2. Plantation of bamboo, vetiver on slope surface to prevent erosion. 3. Provision for hill side drainage.
1. Unconsolidated SFM comprising of rock fragment of parent rock mixed with soil. 2. Rill erosion on slope surface. 3. Oversaturation of SFM due to rainfall creating a local hydrostatic pressure and loss of cohesion on the affected slope.
