On October 17, 2024 at 22:37 UTC, a magnitude 4.2 shallow crustal earthquake struck 90 km NNW of Gorgān, Iran, at a depth of 10.0 km and coordinates 37.6024°, 54.0875°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
