On November 2, 2020 at 19:43 UTC, a magnitude 4.5 shallow crustal earthquake struck 30 km NNW of Nongstoin, India, at a depth of 10.0 km and coordinates 25.7773°, 91.1728°.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
