چکیده

Generally, one of the most problematic tunnel drilled, are water transfer tunnels. These tunnels in terms of risk such as a particularly important constructs is considered and Calculation of strength parapmeters on seismic movements of earth must be done carefully and based on designed criteria. Due to the high sensitivity of the transfer of water in underground, study of engineering geology, seismicity tunnel, tunnel safety and stability control is critical and essential. In this study, try to study of seismotectonic and seismicity of Golab 2 water transfer tunnel located at Koron plain in Isfahan province. The aim of this study was to identify the faults, structural trends and estimation of seismicity parameter using Gothenburg - Richter primary method for 150 Km area of around the tunnel entrance by moment magnitude (Mw).
