Seismic hazard assessment-faulting in the Kerman-Rafsanjan region (southeast of Iran)

The morphotectonic features and seismic assurances are some indicators for the study region as a neotectonic place. In this study, faults have been classified based on the seismic and tectonic evidences in which the role of each fault system and their importance in the seismic assessment that have been revealed. The analysis of morphotectonic in this region indicate the progressive deformation along the right lateral strike-slip zones with N-S striking and the pressure-shearing zones with NW-SE one. The Neotectonic and Morphotectonic studies reveal so active faults which there are no report about their activities. These seismic active faults have cut the Quaternary sediments and also cause some earthquakes. According to the fracture intensity map, the most fracturing (6.5-7) are observed in the south parts of Kuhbanan fault and its segments, the north Gowk segment, the south part of Nayband fault, and along the Jorjafk and Bardsir faults. These fracturing intensity are related to pressure-shear fault zones in this region where occurred many small to large earthquakes.
