Longsoran atau A mass wasting 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.Mass-Wasting is defined as the down slope movement of rock and regolith near the Earth's surface mainly due to the force of gravity. Mass wasting can occur at rates of only a few inches per year and cause little damage and no loss of life, or it can occur at over 100 miles per hour and result in great loss of life and property damage
