Abstract

Fractal dimension of seismic process in wedge-shaped Shear zone of Dehshir fault was calculated by square method which its result was 1. 0003 that is twice the area‘ s (0. 522). It means that the amount is less than the Fractal dimension of the Fault zone network (1. 65). In the 20th century, energy release in the northern part of wedge-shaped Shear zone of Dehshir fault has been along Aghda-Rhmat Abad and Taft fault. Although the hidden activities of thrusts in the southern part can be proved by geological investigations, the appearance of Ernan and Dheshir faults indicates that the energy in the southern part has been used through non-creep strain. Fractal dimension is reduced from the northern parts towards the central and southern part of the shear zone that shows increase in spatial faulted in brittle crust of the above-mentioned zone. It means that most of the energy is spent in deforming and breaking of the Earth's crust in that area. Generally, instability is reduced in apical region of the wedge-shaped shear zone towards the middle and end of it. Quaternary energy in this area has been spent in the growth and displacement of the previous fractures and any new growth has not been made, that is, forces in the area has not changed during successive years and energy release along the faults and previous fractures has been in a steady trend.
