Monitoring the Rate of Vertical Changes of the Ground Surface Using Radar Interferometry Technique and C-Band Time Series; Study Area: Western Part of Horst Shotori (East of Tabas)

This study examines the evidence and effects of young tectonic activities based on the calculation of vertical changes in folds and thrusts in the western part of the Horst Shotori. Quantitative analyses of vertical changes in the western part of the Shotori and the study of factors affecting the extent of these changes have been the objectives  of this study. In order to quantitatively analysis the vertical changes caused by young folds, thrust faults and non-tectonic phenomena in the region, Sentinel 1 radar images were used by radar interferometry method in LiCBAS software. Based on the interpretation of the data, the rate of vertical changes in the Fahlonj anticline is about 7.1 mm and the Sardar anticline is about 1.28 mm, which show the most and the least vertical changes, respectively. In general, vertical changes in the western part of the Horst Shotori, from north to south (northern end of Nayband fault) increase significantly.The high rate and range of changes in the western part of the Camel Plateau, especially in folds and young thrust faults, due to the low rate of inter-seismic deformation and the absence of high-magnitude earthquakes in the time period of the interpretation of the images used in this study, is an important non-tectonic reason. The absence of high magnitude earthquakes in the interpretation period of the images used in this study has an important non-tectonic reason. In the region, a very influential factor in the formation of such changes is the occurrence of severe seasonal floods and the deposition of sediments carried by them in the region. However, the evidence of tectonic morphology observed in the region underscores the current activity of faults, uplift, and the growth of the region's young folds. Evidence such as: Meanderi rivers, Beheaded and Deflected Streams, narrow and deep valleys, alluvial fans rising above the Neogene folds, strata of young alluvial sediments above the limbs of young anticlines in the region, the current activity of faults, uplift and growth of young anticlines.
