What are the natural causes of landslides?

Landslides are generally triggered by a combination of various factors, including both natural and human-induced causes. When considering the natural causes of landslides, several processes can contribute to their occurrence. Geological factors like rock type, slope angle, and weathering play a significant role in determining the stability of slopes. Heavy rainfall, particularly during intense storms or prolonged periods, can saturate the soil, leading to increased pore water pressure and reduced friction between grains, ultimately triggering landslides. Earthquakes also have the potential to initiate landslides by shaking the ground, destabilizing slopes, and causing mass movements. Additionally, the natural erosion of rivers, glaciers, or coastal processes can undermine slopes, making them prone to sliding. These natural causes highlight the dynamic nature of landscapes and the underlying forces that contribute to landslide occurrences.
