On July 27, 2025 at 17:31 UTC, a magnitude 4.0 shallow crustal earthquake struck 28 km SW of Sagaing, Burma (Myanmar), at a depth of 10.0 km and coordinates 21.7329°, 95.7478°.

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.
