Faults and seismicity in the Bakharden-Quchan zone

The Bakharden-Quchan Faulted Zone is located in central part of trusted folding belts of Kopeh Dagh in NE-Iran with an array of active right lateral-strike slip faults by trending NW-SE. the most seismic activities have distributed around and along major fault systems of this zone. Because of neotectonic activities and ends bending of these faults in the Bakharden-Quchan Zone and mechanism changing faults to reverse accompanying with trusting vector have increased stress, shortening, seismicity and high density of earthquakes in their ends. This zone has constantly put unter affection neotectonic stresses convergence of Arabia-Eurasia plates since last phase of Alpine orogeny. In this paper by using of Zmap software and Box counting method were used to compute surface fractal dimension of faults distribution that is shown geometric disorder pattern of earthquakes and forming two cells with high fractal dimension along the Bakharden-Quchan Faulted Zone.
