On July 18, 2020 at 18:38 UTC, a magnitude 4.5 shallow crustal earthquake struck 64 km ESE of Pyin Oo Lwin, Myanmar, at a depth of 11.7 km and coordinates 21.7851°, 97.0208°.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
