The debris slide occurred along HMH road due to the slope disturbance. Prolonged infiltration of water    increases the pore water pressure and reduced the shear strength of the slope forming material during heavy rainfall.

1.Plantation of deep-rooted species of grass such as vetiver grass to strengthen slope. 2. Construction of reinforced retaining wall with sufficient weep holes at the toe can help strengthened the slope by sustaining the weight of the slope mass.
Extensive slope cut for road construction without proper remadial measures and the prolonged percolation of water along the weak planes resulted the planar failure of rock, .
