It is a major debris slide triggered due to oversaturation of thick (4 m) overburden soil due to rainwater and flowing stream, resulting in increase of pore water pressure and shear strength and slope failure along steep slope cut.

1. Trimming of slope on either flank of the slide. 2. Removal of material and rock fragments occurring at critical angle. 3. Proper diversion of flowing water from the crown portion. 4. Provision for hill side road drainage.
1. Thick overburden material (4 m) comprising of soil admixed with rock fragments of country rock. 2. Extensive dissection of slope forming material by flowing stream and rainfall. 3. Steep slope cut for road construction.
