Although gravity acting on an over-steepened slope is the primary reason for a landslide, there are other contributing factors. The term landslide includes a wide range of ground movement, such as rock falls, deep failure of slopes, and shallow debris flows. . . OF SAFETY. Determining slope stability in .
