The topographic position of the landslide provinces, in which similar types of landslides are repeated periodically, are controlled by geology and geomorphological history of the area. Some landslide Provinces are situated along the axis of recent anticlinal movement or active faulting zone without geomorphological control. On the other cases, landslide provinces are distributed on sheared zones of basement complex. Causes of landslides of such types are mainiy steepness of valley walls, thick surficial materials on the estimated old river terrace, representing uprift ground movement of long time.
