Identification of active tectonic areas using fractal analysis (box counting) of earthquakes, lines and waterways of Alborz province

Fractal analysis of earthquakes, lineages and waterways are considered as one of the practical tools to evaluate tectonic activity. With the help of fractal analysis, structural maturity and tectonic dynamics can be evaluated. In this research, using fractal analysis and box counting method and fild studies, the measured fractal dimensions for the designed network of Alborz province were studied and compared. This network consists of 65 square meters with a side length of 12.5 km, for which the fractal dimensions of earthquakes, lines and waterways were calculated separately for all of them. The results of fractal analysis of lineages and network of waterways show high structural activity around Alamut, Mosha, north of Tehran and Taleghan faults located in the northern part and Ipak and Eshtehard faults in the southern part of the study area. In addition, due to the diversity of lithology in the study area, fractal analysis of earthquakes was performed and areas 54, 55, 45 and 46 have high tectonic activity, which these results only in the fractal analysis of earthquakes. Showed. In general, it seems that tectonic activity in Alborz province is strongly affected by the activities of major faults and, of course, the presence of sub-hidden faults (south of Alborz province) in the region, which was found in the analysis of fractal dimensions of earthquakes.
