     the se of zagros belt is dominated by the left-lateral strike-slip faults. the ne-trending gachin fault zone is one of the main transverse faults that cross cut the major structures of bandar abbas zone and continued to the persian gulf, in which deformations of the fault are overprinted on the major structures. the qeshm fault trace shows a left-lateral bending because of the reactivation of gachin fault zone. based on the field, remote sensing and sismotectonics studies, the gachin fault zone is the main cause of the recent deformations on the quaternary sediments in the qeshm island and the surrounding areas. the activities of gachin fault zone are continuing to present time. migration of the earthquakes to the sw shows that this fault is the main cause of 2005/11/27 and 2014/5/27 earthquakes in the area the northeast ward movement of the arabian plate towards central iran is in favour for the reactivation of gachin fault zone. therefore, it is proposed that such convergence can account for the reactivation of similar fault zones in the zagros fold-thrust belt.
