How these factors interrelate is important in understanding what causes landslides along with an understanding of the impact humans have on these factors by altering natural processes.Typically, a number of elements will contribute to a landslide, but often there is one which triggers the movement of material.
In general, the factors which influence whether a landslide will occur typically include slope angle, climate, weathering, water content, vegetation, geology, slope stability and the amount of loading on the slope (overloading).
They can also vary in their extent, with some occurring very locally and impacting a very small area or hill slope while others affect much larger regional areas.
The distance travelled by landslide material can also differ significantly with slides travelling from a few centimetres to many kilometres depending on the volume of material, water content and gradient of the slope.
