On November 12, 2021 at 17:48 UTC, a magnitude 4.3 shallow crustal earthquake struck near Myanmar, at a depth of 19.6 km and coordinates 25.4248°, 96.6407°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
