On June 20, 2022 at 22:00 UTC, a magnitude 4.0 shallow crustal earthquake struck 59 km NW of Bandar-e Lengeh, Iran, at a depth of 10.0 km and coordinates 26.9623°, 54.4940°.

Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
