Abstract
The Landslide happens in mountainous regions due to the catastrophe of slope through
intensive rain and seismicity. The Himalayas is one of the susceptible parts of the world
in the perspective of slope catastrophe hazard; i.e., Mass Movement, especially Neelum
valley is considerable destruction of community infrastructure, highway, and critically
disturbed the tourism segment. Landslide is a common and recurrent phenomenon in the
northern mountainous terrain of Pakistan such as District Neelum. After the 2005 Kash-
mir earthquake, the importance of landslide investigation is increasing. The purpose of
this research is to establish a brief landslide inventory and to determine the relationship
of landslides with causative factors by spatial distribution analysis. With the aid of Google
Earth imageries and feld visits, a total of 618 landslides were identifed in the study area of
3621 km. These landslide localities compared with causative factors. Finally, distribution
maps are generated and analyse their feature class through Digital Elevation Model and
ArcGIS. Landslide intensity is calculated in terms of landslide concentration. Landslide
concentration (LC) is signifcantly found very high in slope gradient less than 30 (1.21) and
the frst 100 m zone around the road network (15.06). A bit higher landslide frequency is
noted in east orienting slopes. In the frst 100 m, zone road network and drainage networks
are 83.49% and 62.78% of the total landslide occurs having LC value 4.6, respectively. The
analysis shows that the steep slopes, an area closer to the road network, drainage network,
barren lands, and Quaternary alluvium of loose material are more susceptible to landslides.
In addition, a landslide classifcation map is also prepared on the basis of feld observation
that shows that debris slides are more dominating.
