Abstract: Recently, the theory of fractal sets and dimensional fractal measurements have been widely used to describe many tectonic processes. The aim of this study was to analyze the morphotectonic status of Damghan and Jazmourian playa as two Subsidance basins using the fractal dimension results of the fault and drainage, which indicates stagnation or tectonic activity. This study uses the box counting method, which is the most widely used analysis method in fractal dimension analysis. The data used in this study are the fault system of the studied basins on the scale of 1. 250000 maps of geology and for the model of drainage on the scale of 1. 250000 the Arc Hydro software. The results show that in the Jazmorian region, the southern part of the hole has the highest fractal dimension of the fault and the lowest fractal dimension of Drainage pattern, which indicates more tectonic activity in this area. after then western range and eastern range is located. Finally, the northern region of Jazmourian experiences more tectonic stillness than other parts, according to fractal data. In Damghan region, the western part with the highest fractal dimension of the fault (1.4034) and the lowest fractal dimension the Drainage pattern (1.3739) is the active tectonic zone. Then the eastern ranges then show the northern range of the tectonic activity basin, in which a large number of earthquakes confirm this, and finally the southern range experiences more tectonic stagnation than in other parts.
