The rock slide has occurred in steep hill slope, in highly weathered and jointed chlorite schist and quartzite due to percolation of rain water through weak planes causing weathering and loosing of joint planes resulting in failure of the rock mass.

No element at risk as slided material is falling in river.
1. Highly jointed and weathered country rock. 2. Due to heavy rain the water percolation through weak planes causing weathering and loosing of joint planes. 3. Steep slope.
