Abstract

An earthquake of September 24, 2013 with a magnitude of 7.7Mw destroyed extensive region of Awaran district located in province Baluchistan in southern Pakistan, the earthquake was nearly 10km deep below the surface of earth. This convulsion brought a havoc in the inaccessible and remote regions and victimized nearly 810 families. This tremor destroyed the non-engineered human structure within 100 km of the earthquake which caused tremendous loss of human lives. In this paper Digital elevation model (DEM) was utilized to study active deformation and mapped the isobase, relative relief, drainag density incision and vertical dissections which indicates that Awaran Fault sinisterly active in NNE-SSW direction and the deformations were highlighted. The high value of drainage density was observed on northern east and in the central region of southern west region of Awaran district. The drainage density is elevated by accelerated erosion in surrounding region. DEM and remote sensing tools proved efficient to study the region efficiently.
