On November 27, 2025 at 22:29 UTC, a magnitude 4.2 shallow crustal earthquake struck 17 km E of Nūrābād, Iran, at a depth of 10.0 km and coordinates 30.1377°, 51.6974°.

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.
