Why do rocks falls occur along the roadside on Chapman's Peak?

Rock falls along Chapman's Peak are primarily caused by weathering processes, such as freeze-thaw cycles and heavy rainfall, that weaken the rock face over time. Additionally, human activities like road construction and landscaping can disturb the natural stability of the slopes, leading to increased risk of rock falls. The steep topography of the area also contributes to the susceptibility of rock falls along the roadside.
