The debris triggered occurred along steep slope cut in weak slope forming material. During heavy rainfall the SFM gets oversaturated resulting in failure due to increase in pore water pressure.

1. Construction of hill side drainage for excess water discharge. 2. Scaling of the slope surface. 3. Removal of tilted and loose plants in the crown portion.
1. Steep slope cutting of the hillslope 2. Weak SFM comprising of soil intermixed with rock fragments of country rock 3. Increase of pore water pressure in the SFM resulted in reduced the shear strength and slope failure.
