Seismicity of Rafsanjan-Zarand Region

Bafq-Baghin fault system has formed by 8 fault segments. On this fault system has not recorded any historical seismic data. Instrumentally earthquakes are located in low depth and their magnitude is small to medium. Morphometric parameters and the presence of fault scarp along the fault segments indicate their activeness. Recent earthquake epicenters of the region (2005-2009) have northeast-southwest trend are located at the intersection of southeast of the Bafq-Baghin fault system. Field investigations and satellite images of region show that the concentration trend of recent earthquake epicenters is located on the cross fault trend that introduced as Rafsanjan-Zarand fault. This fault is one of the X faults in the region that has formed by movement of shear zone.
