On May 27, 2025 at 16:12 UTC, a magnitude 4.0 intermediate depth earthquake struck 23 km WSW of Pakokku, Burma (Myanmar), at a depth of 126.3 km and coordinates 21.2512°, 94.8814°.

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.
