Evaluation and Analysis of Neutactonic Activities and Fault Seismic Power (Case Study: Nir Watershed Basin)

Tectonic geomorphology studies levy -based landfalls and interaction between tectonics and geomorphic processes. Neutactonic studies the shapes on the ground caused by earthquake mechanisms. In order to investigate active neotectonic, neutactonic indicators of the catchment and seismic power are used. In this study, neutactonic activities of the Nir Watershed Basin have been analyzed using geomorphic indicators. Initially, using the GIS10.3 software and the Archydro plugin were extracted under the study of the study area. To accurately calculate any 26 subsidiaries, 1: 25000 topographic maps, 1: 100000 geological maps, 12 meters high height model. Finally, for each of the indicators, the basin zoning map was prepared in five categories. Finally, given the calculated values of each of the indices, the active relative landfill index was extracted for the basin. Due to the index of the relatively active landing index of the study area, it was divided into five high, high, medium, low and very low neutactonic. Based on the results, the highest technical activity is related to subsurfaces 9, 11, 17, 18, 22. Based on the evaluation of seismic power, this concluded that the farmer's relationship with the zareh of 5.98 Richter, Norouzi and Ashjaei with a value of 6.5 and Norouzi was 2.63. The results of this study show that moderate neottonic activity in most of the subsidiaries shows that fault activity is not intensified in these areas and therefore do not pose many risks in residential areas. Will be risky if activated.
