On July 29, 2023 at 22:29 UTC, a magnitude 4.4 shallow crustal earthquake struck 84 km W of Minbu, Myanmar, at a depth of 43.9 km and coordinates 20.1463°, 94.0671°.

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.
