This is a slope cut induced natural failure. Slope cutting for road construction resulted in removal of toe support. Further saturation of weathered overburden after rainfall caused loss of cohesion and friction and ultimately resulted in failure of slop

Hanging roots and fallen trees have been observed over the crown and failed material respectively. Debris contains considerable amount of boulders also.

Removal of loose material and failed uprooted trees from the slope.
Dressing of crown.
Re-profiling of slope with creation of intermediate bench.
Complete cleaning and lining of hill side drain.
Construction of suitably designed protection wall with weep
Increase in pore pressure and reduction in strength and friction of highly weathered basalt due to saturation of mass by rainfall resulted in downhill movement of material. Dislodging of basaltic boulders has also taken place.
