Abstract
The Zagros fold-thrust belt (ZFTB) in Iran is the result of the closure of the Neo-Tethys Ocean and the convergence of the Arabian and Eurasian continents. The influence of earthquakes above Mw 6 triggered by fault activity in this area on the surrounding salt diapirs has always been one of the hot issues in the field of geosciences. The slip factor of coseismic slip distribution of Sayeh Khosh Mw 6.1 on July 1,2022 in southern Zagros, Iran, is re-estimated and applied to the linear inversion of fault slip distribution of these two seismic events. Finally, the CFF stress transfer caused by two sources is calculated, and the results show that the MFF fault is thrust and right-lateral strike-slip. The subduction power source comes from the continental collision between the Arab plate and the Eurasian plate, and the salt rock detachment mechanism is formed.
