Definition A landslide is a geological phenomenon which includes a wide range of ground movement,such as rock falls,deep failure of slopes and shallow debris flows,which can occur in offshore,coastal and onshore environments. Landslides are known also as landslips,slumps or slope failure

Definition the force of gravity pre-conditional factors build up specific sub- surface conditions that make the area/slope prone to failure, whereas the actual landslide often requires a trigger before being released

the influencing factors slope angle, climate, weathering, water content, vegetation, overloading, geology and slope stability

The movement of landslide The movement of landslide material can vary from abrupt collapses to slow gradual slides and at rates which range from almost undetectable to extremely rapid. Sudden and rapid events----->the most dangerous Extremely slow landslides might move only millimetres or centimetres a year and can be active over many years.---->not a threat to people but to property
