Zagros fold and thrust belt as a part of Alpine-Himalayan orogenic belt is the most seismic active region of Iran. A doublet earthquake (MN 6.2 and MN 6.3) on 2021 November 14 occurred ∼20 km southeast of Fin of Hormozgan Province, in the southeast Zagros Mountains of Iran. These earthquakes killed one person. Based on the epicenter distribution of aftershocks, focal mechanism solutions, and satellite images of the region, the 2021 Fin Hormozgan doublet earthquake likely occurred on a thrust fault with a slight strike-slip component. Likely, these earthquakes ruptured an SSE-dipping thrust in the hanging wall of the Mountain front fault.
