Abstract
The earthquake triggered enormous landslides on 8th October 2005 in the various areas of Pakistan
especially in Balakot Region. This research paper fulfilled the urge to develop alternative landslide
planning based on the consideration of landslide preventing measures using GIS (Geographical Informaton
Systems) techniques. This specific type of land use planning differs from traditional type of land use
planning due to consideration of the probable hazard of landslide disaster by applying zonation methodology
for finding the appropriate suitable areas for various development purposes. The various parameters e.g.
elevation, slope angle, forest/ vegetations, faults, landslide zones, and rainfall were utilized as GIS data
themes in the vector format. The different GIS techniques were used: (i) Clipping the data layers; (ii)
Spatial analysis by converting the vector layers into raster format; (iii) Classification of data themes into
certain classes; (iv) Overlaying the data themes and (v) Map calculation techniques through GIS standard
software. This applied research has found that various different regions such as high suitable, moderate
suitable, low suitable and unsuitable may be considered as preventive measures from the probable hazard
of the landslide disaster in future for rehabilitation and redevelopment purpose which can save human
lives, residential and commercial infrastructure in future. It is believed that the various predicted regions
for preventing landslide hazards can be very beneficial to the decision makers for the redevelopment of
the region in future.
