Fractal geometry quantitatively analyzes
the irregular distribution of geological features,
highlighting the dynamic aspects of tectonics, seismic
heterogeneity, and geological maturity. This study
analyzed the active fault data along the Kuhbanan fault
zone in southeastern Iran by applying the boxcounting method and observing the changes in
Coulomb stress and tried to find the potential
triggering parts. The entire region was divided into 16
subzones with the box-counting method, and then the
fractal dimension (D) in each zone was calculated. The
analysis of the fractal dimension for active faults and
earthquake epicenters along with the seismicity
parameter (b) and their ratio in the Kuhbanan region
indicates an imbalance between seismic fractals and
faults. This finding suggests that the area may have the
potential for future earthquakes or hidden faults. In
conjunction with b-value and changes in Coulomb
stress change, D-value analysis reveals intense tectonic
activity and stress accumulation, particularly within
the Ravar, Zarand, and Kianshahr sections. It may be
considered a potential location for future earthquakes.
The changes in Coulomb stress resulting from the 2005
Dahuieh earthquake have also placed this region
within the stress accumulation zone, potentially
triggering the mentioned areas. This integrative
approach, backed by historical earthquake data,
highlights the impact of fault geometry and stress
dynamics, offering an enhanced framework for
earthquake forecasting and seismic risk mitigation
applicable to other tectonically active areas within the
Iranian plateau.
