On October 5, 2021 at 23:27 UTC, a magnitude 4.4 shallow crustal earthquake struck 207 km NNE of Shi Yomi, India, at a depth of 31.4 km and coordinates 30.3670°, 94.8040°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
