| description | Bazman volcano, in the South East of Iran, northwest of the city of Iranshahr and is located in the north of the city Bazman. The aim of this study was active tectonic basinemanating from the Bazman volcano (with a focus over the city Bazman) and its environment as well as the level of tectonic activity in the region is the relative. In this regard has been paid to the study of morphometric indices The morphometric indices which include over Drainage Basin Asymmetry (Af), Sinuosity Front Mountain (Smf), Longitudinal slope gradient of River (SL), Floor width to valley Height (Vf), Hypsometric Integral (Hi), Mean axial tilt channel (MASC), the shape of the basin (Bs) for the study of tectonic activity in the area has been used. These indicators have been studied to evaluate the relative tectonic activity (IAT) of the basins and sub-basins of the region. The results of geomorphic analyzes are expressed as a relative index of tectonic activities (IAT). This index shows the tectonic activities of a region in four categories of low, medium, high and very high activity. on the Base of studies, the classification of tectonic activity is as follows: Area with very high relative tectonic activity in the northwestern and northeastern parts of the study area, These basins are located in the north-northeastern and eastern parts of the region, which is mainly affected by lithology (especially around the volcano), the young vertical movement of faults and active tectonic structures in these basins. The zone with moderate relative tectonic activity is located in the middle and southern parts of the region and the zone with low relative tectonic activity is located in the basins of the central, western and southwestern parts of this zone. The results of the analysis of indicators indicate tectonic activity in the area of Bazman volcano and its surroundings. Due to the located of Bazman city and population centers in the vicinity of the volcano, especially its southeastern part, the possibility of geological hazards in the future is inevitable. |
