Abstract


The serious concern in identifying vulnerable zones is consideration of either one of the aspects, human lives or infrastructure but both should be taken inn account for predicting accurate vulnerable zones. This research has considered the both type of control event parameters to detect the different landslide probe vulnerable zones in Balakot, Pakistan where on 8 October 2005, a terrible earthquake induced various landslides which not only killed human being but also ruined entire city. This research is Geographical Information systems (GIS) based, applied, qualitative using Heuristics approach and quantitative using weight of comparison matrix method to justify the enveloped criteria and its weight with standard results. The different techniques of (GIS) e.g. sub-setting the data, vectorizing the grid data into vector data, classification, and map calculation have been utilized. The conclusion of this reasecrh was detection of different levels of vulnerable zones into five classes such as very high, high, moderate,  low  and no vulnerability zones. It is assure that this type of detected different vulnerable areas can be useful for the decision makers to redevelop the region in future so that human live and socoio-ecoomic infrastructure may be saved for future.
