On February 2, 2026 at 21:43 UTC, a magnitude 3.9 shallow crustal earthquake struck 35 km WSW of Mohr, Iran, at a depth of 10.0 km and coordinates 27.4248°, 52.5563°.

Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
