GIS-based Analysis of Relative Tectonic Activity in Southeast of Iran with a focus on Taftan volcano

Taftan volcano has been located in southeastern of Iran and zone of Nehbandan-Khash (Iran Eastern Mountains). It seems that both the young volcano and active tectonic have played an important role in morphometry in this area. Geomorphic indices have been used to study tectonics in this area. These Indices include Drainage Basin Asymmetry (AF), Transverse Topography Symmetry (7), Mountain Front Sinuosity (Smf), River Slope Length (SL), Floor Width to Valley Height (VF), Hypsometric Integral (Hi), and Drainage Basin Shape (BS). These Indices have been used to evaluate Relative Active Tectonic (IAT) of basins and sub-basins of the area. Recently, it is found that Neo Tectonic has played an important role in geomorphic evolution. On the basis of this model, three tectonic zones are recognizable in that area: (Zone with High Relative Tectonic) that found in sub-basins of 4-B and 9-C. (Zone with moderate Relative Tectonic) that found in the wide-area (northeast) including Dargiyaban and Sadabad Faults. (Zone with Low Relative Tectonic) that only found in sub-basins 5-C and 8.
