pattern of seismicity around zagros main recent fault

The main zagros recent fault (mrf) is the post pliocene surface expression of the arabia - central iran suture in west and northwest iran (braud, j. and ricou, l.-e., 1972). the fault is constituted by several strike-slip segments with left-hand stepping arrangement and transtensional to transpressional mechanisms in with respect to their strike (tchalenko & braud, 1974). earthquakes with strike-slip, normal and reverses mechanisms have occurred along the fault, while thereis no convincing seismotectonic explanation for the occurrence of these seismic events due to large uncertainties in their location.
