On May 25, 2021 at 19:23 UTC, a magnitude 4.1 intermediate depth earthquake struck 19 km ESE of Mawlaik, Myanmar, at a depth of 99.6 km and coordinates 23.5930°, 94.5857°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
