Landscapes in tectonically active Hindu Kush(NW Pakistan and NE Afghanistan) result from a complex integration of the effects of vertical and horizontal crustal block motions as well as erosion and deposition processes.Active tectonics in this region have greatly influenced the drainage system and geomorphic expressions.The study area is a junction of three important mountain ranges (Hindu Kush-Karakorum-Himalayas) and is thus an ideal natural laboratory to investigate the relative tectonic activity resulting from the India-Eurasia collision.We evaluate active tectonics using DEM derived drainage network and geomorphic indices hypsometric integral(HI),stream-length gradient (SL).fractal dimension(FD).basin asymmetry factor(AF).basin shape index(B_s),valley floor width to valley height ratio(Vf) and mountain front sinuosity(S_(mf)). The results obtained from these indices were combined to yield an index of relative active tectonics (IRAT) using CIS.The average of the seven measured geomorphic indices was used to evaluate the distribution of relative tectonic activity in the study area.We defined four classes to define the degree of relative tectonic activity:class 1 very high(1.0≤IRAT 1.3);class 2-high(1.3≥IRAT<1.3):class 3—moderate(1.5≥IRAT<1.8);and class 4—low(l.8≥1RAT).In view of the results.we conclude that this combinetl approach allows the identification of the highly deformed areas related to active tectonics.Landsat imagery and held observations also evidence the presence of active tectonics based on the dellected streams,deformed landforms.active mountain fronts and triangular facets.The indicative values of IRAT are consistent with the areas of known relative uplift rates,landforms and geology.
