Fractal analysis of features and geological structures are used for Tectonic activityof an area. Computing the fractal dimensions from fracture density changes in the north of Lali in NE Khuzestan indicateS increasing in fractures fractal dimension from south to north. In southest, surveyed portion fractal dimension is about 1.398 and in the northest surveyed portion increases to 1.617. Stream fractal dimension increases from north to south. In northern fractal dimension of the studied section is about 1.805 and in southern section it increases to 1.862. Earthquake epicenters fractal dimension is increasing from east to west importantly. Adapting the fracture density fractal dimension and earthquakes epicenters is increasing from southeast to northeast. Streams density is decreasing from southern to northeast in this area. Affecting the agent of existing thrusts  that caused to increasing the high, fracture density and earthquake in area.
