On April 4, 2023 at 20:08 UTC, a magnitude 3.8 shallow crustal earthquake struck 56 km SSE of Mohr, Iran, at a depth of 10.0 km and coordinates 27.1047°, 53.1540°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
