Morphotectonic analysis with the help of geomorphic indices is considered as a tool for the identification of new and active structures affected by tectonic movements in special areas. For this purpose, indicators such as Mountain Front Sinuosity index (Smf), (Vf), (Af), (S), (Sl), (T), form factor basin, basin shape, slenderness ratio and stretch ratio index of basin (Bs) associated with alluvial fans, including fan of bending β, fanning coefficient and longitudinal profile were calculated. The tools in this study include: the topographic maps, field geology invesigations, satellite imagery, digital elevation model (DEM), IRS satellite images of the region, GIS and Global mapper softwares. The results of the analysis of topographic data, evidences from field observations and data obtained from geomorphic indicators, all suggested that the area is active from neotectonics viewpoint. Based on the classification of LAT, the study area is classified in class 1, which indicates intense tectonic activity. Based on the results, the northern part of the Dorud fault is more active than the southern section in terms of neotectonic movements.
