Abstract :
Kerman Province is one of the seismic regions of Iran, which has many faults with different trends. Therefore, addressing the issue of tectonic and seismicity in this province can be useful in various fields such as crisis management. In this research, we used topographic maps, geological maps, aerial photos, satellite imagery and seismic catalogs of the Institute of Geophysics of the University of Tehran. In this way, the active tectonics of Kerman province in the Lut and Jazmurian basins and their relations with the seismicity of this province were examined. From geomorphic indicators such as longitudinal river gradient (SL), drainage asymmetry index (AF), topographic symmetry factor (T) and index and basin shape ratio (BS) has been used to determine the tectonic condition of the basins. Although, using the Relative Ratio Index tectonic activity (lat) in the tectonic of each basin was determined that both basins are active, but their tectonic activity is not the same. Shahdad basin has high to moderate activity and Jazmurian basin has a low activity. Also, in order to investigation of active tectonic of the province, geomorphic quantitative indicators were also used.
