Describe mass movements and identify areas in South Africa prone to them, including contributing factors.

Mass movements, also known as landslides or slope failures, are the downslope movement of rock, debris, or earth under the influence of gravity. They can be triggered by factors like heavy rainfall, earthquakes, volcanic eruptions, and human activities such as deforestation or construction.

In South Africa, areas prone to mass movements often include:

• Mountainous and hilly regions: The Drakensberg Mountains, Cape Fold Belt (e.g., Western Cape), and parts of the Eastern Cape and KwaZulu-Natal are susceptible due to steep slopes and varying geological conditions.
• Areas with specific geology: Regions with unstable soil types, weathered rock, or fault lines are more vulnerable.
• Informal settlements: These are often built on unstable slopes or floodplains, increasing the risk of mass movements impacting human settlements, especially during heavy rainfall events. Examples include informal settlements around major cities like Cape Town, Durban, and Johannesburg.
