associated either to the bent termination of some known faults like Manjil in the region or to the active structures with the same orientation especially those located north of Rudbar. Distribution of the focal depths indicates that in the west the seismicity is vertical and probably related to the Kabateh rupture. In the central parts, the dip of seismicity progressively changes from 45° to vertical. Reverse faulting is associated with the Eastern part of the Manjil fault, dipping northward. The calculated focal mechanisms confirms the partitioning of oblique convergence of the Central Iran toward South Caspian basin accommodates by reverse faulting on the Manjil fault and strike-slip faulting on the Zard-Goli fault.
