On April 9, 2026 at 20:02 UTC, a magnitude 4.2 intermediate depth earthquake struck 83 km SE of Phek, India, at a depth of 113.5 km and coordinates 25.1876°, 95.1360°.

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.
