The shallow rotational debris slide occurred due to weathered SFM is unstable along the extensive slope cut. Also, pore pressure of SFM increasing during rainy season, which reduces the shear strength of SFM and the material slided.

1. Removal of slided debris material 2. Repairing of damaged concrete retaining wall with sufficient weep holes.3. Natural drainage has to be diverted with culvert
1. Slope forming material is comprised of weathered intercalation of grey shale, shale and siltstone of Disang Group. This makes the SFM unstable along extensive slope cut during rainfall 3. The affected slope is dissected by drainage, which increases po
