Fractal analysis is one of the most appropriate methods for determining the quantitative level of tectonic activity, structural maturity and the degree of heterogeneity of seismicity. In this paper, the fractal dimension, obtained by the box-counting method as the most general approach for the calculation of active faults, streams and the epicentral earthquakes which occurred from 1900 to 2019. For this purpose, the whole area is divided into 16 zones by Log-Log graph and then the fractal dimension of each zone is calculated. Fractal dimension calculation of active faults, streams and earthquakes occurring in Khuzestan zone, indicates a decrease in tectonic activity from east to northeast towards the center and south.
