The debris slide, has initiated by slope excavation.  Seepage of water along the SFM, increase pore water pressure and reduced the shear strength of the slope forming material during heavy rainfall.

1. Removal of failed debris material on the drainage and road side. 2.  Trimming of crown scar.
Increase of pore water pressure in the  overburden soil during rainfall reduced the shear strength and resulted to slope failure.
