The shallow rotational debris slide occurred due to over saturation of SFM during intense rainfall

1. Removal of slided debris 2. Construction of lined hill side road drainage.
Overburden got saturated during intense rainfall which increased the pore water pressure, reduced the shear strength, cohesion and internal friction angle of the slope forming material.
