  Kuhbanan fault system, as one of the intracontinental faults of central Iran, is recognized by considerable seismogenic activities and modern morphotectonics evidences with a strike-slip (reverse component) motion. According to the geometric and kinematics data, Kuhbanan fault has been divided into 5 segments (S26, S27, S28, S29, S30) in Bahabad region. Measured geomorphic indices of ratio of valley-floor width to valley height (Vf) and morphology of the valley (V) manifest the maximum denudation rate for the S28 segment. The mean calculated values of mountain-front sinuosity (Smf) and %facet parameters for different segments of the fault are 1.1 and 83.16, consequently. Regarding to these geomorphic indices, a denudation rate of about 2-4 mmyr-1 is suggested for this region. According to reconstruction of Kuhbanan fault since 360 ka, minimum horizontal cumulative displacement of 750 m and minimum slip rate of about 2-1.4±0.1 mmyr-1 is inferred from well preserved geomorphology in the northern segment of the fault. Applying this horizontal cumulative displacement causes reconstruction of geomorphic markers such as drainages and shuttered ridges. Manuscript profile

  The Ghezel Ozan River, the longest river system in the country, has responded to tectonic deformation thoroughly. In this paper the role of lineaments in making of active deformations via detection and characterization of geomorphic anomalies in the Ghezel Ozan River and correlation with magnetic lineaments is specified. In this study, the first fluvial anomalies have been identified on the satellite images and approved through DEM and field observations. Then these anomalies have been correlated with magnetic lineaments extracted from aeromagnetic maps and so the sub-surface active folds and faults have been recognized. Most ofthemagnetic lineaments in the Ghezel Ozan River basin have caused the geomorphic anomalies in the length of the river. The lineaments with trend of NW - SE have created various anomalies such as variations of channel pattern of the river, deflection of the river course and knick points in longitudinal profile of the river. The lineaments with trend of NE - SW have only straightened the course of the river. Manuscript profile

  There are some active and quaterner faults in Tabas region such as Kalmard, Tabas, Nayband,Cheshme Rostam, Zenoghan, Ghoorichay, Anarak-Takhtnader and Ghadir that play role in seismicityof the region. Seismotectonic properties and seismicity effect estimatation of any sources is necessaryfor resistation of the cities. For this reason, amplification of alluvial sediments that affects the factorsof strong ground motion such as acceleration, velocity and displacement, is important too. Earthquakezonation and risk analysis are important for Tabas city because of the city importance and existence ofmain industrial, economical centers and major ways in this city. Recorded earthquakes with Mb = 7.6represented that the region is tectonically active. Based on geophisic studies and active tectonicindexes and earthquake risk estimation of the region, possibility earthquake event with M=6, is 50%,for return period 75y. In the center of the city, maximum horizontal and vertical acceleration for returnperiod 475y resulted from the potential earthquake, are 0.4g and 0.2 g, respectively. Manuscript profile

  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. Manuscript profile

  The northwest zone of Saveh city is located in the Indes , Kooshk e Nosrat, Avaj and Ipak fault zones. Indes, Kooshk e Nosrat, Avaj and Ipak faults are considered as the major faults in central Iran, which are also active in the Quaternary and the their last movements are attributed to the present time, therefore, the estimation of morphometry in order to identify the effect of active tectonics on the tectonic evolution of drainage basins seems necessary. Therefore, in this study, six important morphotectonic indices were analyzed including longitudinal gradient of the river, asymmetry of drainage basin, hypsometric integral, Drainage basin shape, the ratio of the floor width to the valley height and mountain front. In order to model the formation of basins in the studied area, Arc Hydro software (Arc GIS add ins) has been used based on data derived from a digital elevation model. Then, 6 morphotectonic indices have been compiled and classified on each of the basins. Finally the Active Tectonic Index (IAT) has been calculated, according to which the study area has been classified into 4 categories including very high, high, intermediate and low tectonic activity. According to the IAT index, 5% of the study area shows very high tectonic activity, 25% of the studied area has high tectonic activity, 65% of it has the average tectonic activity and about 5% of the tectonic activity are low. In this study, the highest level of tectonic activity can be seen in the north-eastern part of the area. In most sectors, the level of activity is high and intermediate, which is related to the activity of Kooshk-e-Nosrat, Aipak and Avaj faults. Manuscript profile

  The geomorphic analysis of mountain fronts, anticlines and folded belts can provide valuable insights about the recorded tectonic history of any given region. Therefore, such studies at a regional scale have been frequently undertaken using morphotectonic analysis to delineate areas having higher tectonic activity. Keteh Pifak anticline is located in the northeast of Eyvan-e-Qarb township, north of Ilam province and is considered as a part of the Zagros simply folded belt. In this research, with the aim of evaluating the active neotectonic movements in the Keteh Pifak anticline, the six geomorphic indices such as: Ratio of Valley Floor Width to Valley Height (VF), Percentage Undissected Escarpments (EU), Percentage Dissected Mountain Fronts (FD), Fold Front Sinuosity (FFS), Fold Symmetry Index (FSI), Aspect Ratio (AR) and Relative Tectonic Activity Index (Iat) have been used. The morphometry of Keteh Pifak anticline were determined using topographic maps, satellite imageries and field works. Also, the structural, tectonically and lithologically data were obtained using geological map (5257 sheets No) with 1:100,000 scale. Results show that high values of FFS, EU, AR indices and low values of FD, VF, FSI indices indicate the young and asymmetry of this anticline, the continuation of neotectonic forces and low erosion in the anticline. Also, based on the Iat index, it was determined that this anticline at class 3 of activity. Field evidence in the study area such as narrow valleys (V-shaped), straight, steep and faulted escarpments, asymmetric fold show that this anticline is tectonically relative active.

  The study of active tectonic is significant due to assessment of the risk of earthquake in different areas, especially those where relatively high tectonic activity was observed in Holocene and Pleistocene. The objective of present study is to compare the tectonic activity levels in banks of Hable, Jajrood, and Haji Arab rivers through morphometric analyses. The ratios determined in the present study include the proportion of valley floor width to its height, mountain front-side sinuosity, and longitudinal slope of river, drainage basin asymmetry, and ratio of drainage basin shape, ratio of inverse topographic symmetry of the basin, ratio of drainage basin symmetry, and symmetry ratio of the basin all of which represent the tectonic activity of a region in four categories of low, medium, high and very high. For active tectonic estimation, topographic maps (1: 250,000 and 1: 50,000) along with geological maps (1: 20,000 and 1: 25,000) along with 10m DEM of the studied regions were used. For generation of basins on the studied region, ArcGIS Software was used to deal with a database of digital elevation model. Certain phenomena such as fault scarp, multi-generational alluvial fans, and linear valleys are among morphologic evidence that are abundantly found in basins with high and medium tectonic activity. The results suggest that among the examined basins, the Jajrood basin is more influenced by tectonic activities and this is due to the influence of Jajrood Fault on this basin Manuscript profile
