Wazri landslide took place on 12 September, 2017 in Yamuna valley while another rock slide activity is reported to have started to the upslope of the Kunwari village on 10 March, 2018 in Pinder valley. The 106 houses and around 400 persons were affected in Kunwari landslide while around 250 meters road got blocked in Wazri landslide. Being tectonically active zones, these areas are controlled by structural elements like thrusts and faults. Seismicity creates disturbance in these tectonic features and eventually causes landslide within their vicinity. Additionally, slope aspect, slope angle, high relief, low cohesion and friction of slope materials and seepage are some considerable causative factors for the slope instability in the areas. Construction of houses beside drainage network, unplanned agricultural practices and excavation for road construction over steep slopes further enhanced the susceptibility of landslides. Because of the presence of thick debris materials and ground cracks on the slopes, these sites are still in danger. The purpose of this study was to highlights factors contributing to landslides and recommendations for ensuring safety of human being.
