On January 13, 2022 at 19:03 UTC, a magnitude 4.1 intermediate depth earthquake struck 91 km SE of Phek, India, at a depth of 94.9 km and coordinates 25.0326°, 95.0765°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
