A doublet earthquakes event including two main shocks with a magnitude larger than Mw 6.0 occurred on 1 July, 2022 in the Zagros fold-and-thrust belt, southeast Iran. The coseismic InSAR deformation field shows that this event caused significant surface uplift due to fault-related folding in the seismic zone. The estimated preferred faulting model suggests that a higher dip angle fault (maximum slip of ~1.1 m), and an overlying gentle dipping fault (maximum slip of ~1.2 m) within the Bandar-e-Lengeh Anticline, are responsible for the first and second main shocks, respectively. The calculated Coulomb failure stress change suggests that the first main shock has a significantly positive triggering effect in the second main shock. The coseismic deformation due to this doublet earthquakes is equal to the accumulated interseismic deformation for the past ~104 years. Finally, the salt diapir activity may affect the generation of the earthquake in the seismic zone.
