<p>Tabriz veniar dam by reservoir volume about 360 milion cubic meters and 50 meter height of river bedis of gravel dam by clay nucleus.this dam is along with north Tabriz fault of active one by historical background of earthquake. Therefore, it requires studying possibility of inductive earthquake occurring on this dam.we have considered noram tensions،،and cross one ، ،in limit of 40-45 kilometer from dam by considering reservoir loads in the center of earthquake for1&times;1 network kilometer and on north fault of tabriz in order to study potential of inductive earthquake on veniar Tabriz dam. in this study,we have used of 19 december 2007 earthquake affairs in which shows stumbling direction in right direction and is concordant with north Tabriz fault. We have used of speedometer apparatus in order to determine earthquake affairs andrecognizing fault face and analyzed result by mathematic models. According to the amount of analysis, we concluded increasing earthquake deep decreases reservoir effects. The most effect of reservoir is on 1-4 kilometers deep and also the amount of fault satability S_r(t) is less than zero on north Tabriz fault in which indicated the influence of veniar dam reservoir on Tabriz fault that push forward earthquake.</p>
