On December 21, 2021 at 21:08 UTC, a magnitude 5.0 shallow crustal earthquake struck in the Andaman Islands, India region, at a depth of 10.0 km and coordinates 10.2993°, 94.0416°.

Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
