Samira Naqi

Landslides, mass movements of rock, debris or earth down slopes are worldwide phenomena which cause significant damage and an estimated 5000 fatalities each year. They are caused by the interplay of various natural and anthropogenic factors and may occur under diverse geo environmental conditions. Goal of this research is to gain a deeper insight into the causes and precursors of landslides, which will facilitate more accurate identification of landslide prone locations and, enable early detection of landslide events. As catastrophic events, landslides can cause human injury, loss of life and economic devastation, and destroy construction works and cultural and natural heritage. A number of landslide occurred in Rawalakot-Arja valley. These landslides were complex and very sever and caused number of damages to house, land use and peoples of the area. There were number of slides reported each year in the Rawalakot-Arja valley but among them some important slides are discussing in this paper. Geologically it is composed of Siwalik formation. In this valley the six main slides have been selected for study. These are Mujahidabad Slide, Mudflow at Sanadi, Khadd Bazar Landslide, Bosa Gala Landslide, Narh-Gran Landslide and Sokkini-na-par Landslide.
