This study aims to assess the seismic potential in eastern Iran using statistical analysis of seismic data, interpretation of geological structures, and examination of the dynamic behavior of active faults. Historical (1900-1964) and instrumental (1964-2024) seismic data were analyzed using Zmap and ArcGIS software after applying the necessary corrections. Key parameters, including the fractal dimension of fractures (D-value) and seismic moment rate, were calculated as primary indicators for determining the seismicity of the study area. Fractal analysis was conducted using the grid-based technique to evaluate the spatial distribution of earthquakes. Additionally, the seismic moment rate was calculated using the triangular subdivision method. The results of this study indicate that the faults in eastern Iran have lower b-value values, suggesting increased tectonic stresses and, consequently, a higher probability of larger earthquakes. These analyses provide a powerful tool for understanding earthquake distribution patterns and their relationship with active fault structures, contributing to seismic hazard assessment and disaster management. Moreover, a high seismic moment rate has been observed in areas with crustal stress accumulation, which can be utilized for earthquake hazard prediction and the design of earthquake-resistant structures.
