Rockfalls occur when a particle or rock fragment breaks off from the parent rock. The movements involved in rockfalls are falling, rolling and bouncing. The result of these movements are individual fragments that disintegrate on impact. Occasional major slopes collapses may take place.
Causes Of Rockfall:
- geological weakness
- weathering processes
- earthquakes
- severe storms
- heavy rainfall
The resultant slope form is mainly free face and rectilinear/ constant gradient slope. The surface from which rocks were detached forms the steep cliff while the rock debris accumulates at the base and forms the talus slope.
