The slope is predominantly composed of loose unconsolidated parent rock mass intermixed with in-situ soil. Moreover, the drainages on the slope tend to incise the slope material and cause further erosion during heavy rainfall

i.Removal of slide materials and precariously hanging trees from the affected slope. ii. Removal of slide materials to avoid blockage of weep holes.
i.Slope forming material is composed of loose unconsolidated parent rock mass intermixed with soil. ii.Saturation of overburden and increase in pore pressure and loss of cohesion during rainfall.
