2026-07-23 18:21:37 UTC (2026-07-23) · approx. 12:21 AM UTC+6 local
On July 23, 2026 at 18:21 UTC, a magnitude 4.0 shallow crustal earthquake struck 58 km WSW of Pyay, Burma (Myanmar), at a depth of 54.3 km and coordinates 18.6720°, 94.6933°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
