The shallow rotational debris slide occurred due to extensive slope cut. The weak shale and siltstone material unstable along the slope.

1. Removal of slided material. 2. Construction of retaining wall with sufficient weepholes. 3. Stabilize the slope by benching 4. Maintenance of hillside drainage.
Slope failure occurred on cut slope due to oversaturation of thick slope forming material predominantly composed of highly weathered shale and carbonaceous shale.
