On August 26, 2022 at 04:52 UTC, a magnitude 4.6 intermediate depth earthquake struck 103 km SE of Phek, India, at a depth of 91.4 km and coordinates 25.0099°, 95.2338°.0 This earthquake was detected by 45 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
