Mechanical Interaction among Large Earthquakes in Eastern part of Iran

Human being has been faced with destructive phenomenon specially earthquake for a long time. Knowing about the time and area of major earthquake and aftershocks is so necessary to mitigate the damage of financial and life by warning the earthquake or aftershocks happen before it really happened. Maybe this day we can't predict the earthquake exactly but the study about the information of previous earthquakes can identify the potential land that have Earthquake Bloodbath and with this knowing in building construction we can mitigate the damage due to the earthquake.     The tendency of rocks to fail in a brittle manner is thought to be a function of both shear and confining stresses, commonly formulated as the Coulomb failure criterion. Here we explore how changes in Coulomb conditions associated with one or more earthquakes may trigger subsequent events.      Study of Stress changes in earth's crust is useful for the predicting earthquakes. Analysis of Coulomb stress changes has been used in many seismic areas. These researches showed that the area and the speed of next earthquake will affect by the static stress changes which are the result of historical earthquake in this area.
