On August 22, 2020 at 22:56 UTC, a magnitude 4.2 intermediate depth earthquake struck 81 km NW of Monywa, Myanmar, at a depth of 102.8 km and coordinates 22.5997°, 94.5465°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
