Abstract

Existence of seismic activity history and high rate of tectonic activity in the region, which indicates that the study area is releasing energy in the pre-seismic stage and as a result in some points of stress accumulation, which will lead to high seismic potential in the future. For this purpose, the active faults of the study area have been drawn and the scatter map of the relative tectonic activity level has been evaluated with instrumental seismic data. Finally, the maximum seismic acceleration of the area has been calculated and the area lines have been obtained by PCA method. After examining the area lines, it was found that lines L1, L2, L3, L4, L5 do not have a counterpart in the aerial magnetic map and therefore are a surface fault. L6 has good compatibility with F-9 magnetic line and surface lines L2, L3, L4, L5 do not have any compatibility with any of the faults exposed in the geological map and magnetic line and their faulting needs to be investigated. It has a desert.
