On July 23, 2023 at 06:47 UTC, a magnitude 4.6 shallow crustal earthquake struck 172 km W of Pyay, Myanmar, at a depth of 10.0 km and coordinates 18.5620°, 93.6142°. This earthquake was detected by 29 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
