One of the important issues in the country’s industrial sector is the reduction of risks from potential earthquakes. This issue is particularly significant in the field of dam construction, as even a minor incident caused by an earthquake can lead to irreparable damages. Changes in regional stress balance can result in induced earthquakes. This study aims to identify the seismicity of the area by examining aftershocks and microseisms, identifying seismic faults within the region of the Roudbar-Lorestan Dam, and analyzing the impact of the dam during wet and dry seasons on seismicity. This information is intended to be useful for advancing future goals and constructing important structures. Recording and analyzing microseisms and examining the relationship between seismicity and existing faults in seismic areas are of high importance. A local seismic network is necessary for conducting such studies. Furthermore, selecting the best model for reading the phases of S and P waves using artificial intelligence, as well as conducting surface and depth location of earthquakes and assessing the potential relationship between the dam and seismicity in the area, are among the functions of this research. The results of the analysis of local earthquakes recorded in the vicinity of the Roudbar-Lorestan Dam and power plant over a one-year period in 2017 provide valuable information regarding the confirmation of seismic activity of regional faults and their geometry. The findings of this study identify the main young fault of the Zagros (MRF) as a major pathway in the convergence of the Arabian and Eurasian plates in the region. Results from statistical studies and examination of seismic parameters indicate that an increase in weight load due to rising water levels in the reservoir could either stabilize or activate the terminal section of this fault.
