Understanding how the movement of faults and deformation affects such as motion-induced surface stress and strain, which is very important in seismic regions. The best way to learn about the effects of fault movement is modeled. For example, the modeling of surface displacement or deformation and the amount of damage earthquake can be estimated by the model. Coulomb stress changes can be modeled or predicted earthquake aftershocks or future Earthquakes. we employ assumptions on the orientations, rupture lengths and average slip associated with each earthquake to calculate stress changes. Using this model, we displacement, stress and strain at any depth in the Earth's surface acquired. In this study the modeling of earthquakes Mw= 6.5, Mw=6.3 Ahar-Varzaghan. The earthquakes induced displacements, strains and stresses were calculated at the surface at an average depth and its aftershocks for 10-km Ahar and 4 km Varzaghan.
