2025-10-17 16:39:18 UTC (2025-10-17) · approx. 10:39 PM UTC+6 local
On October 17, 2025 at 16:39 UTC, a magnitude 3.9 shallow crustal earthquake struck 22 km N of Yangon, Burma (Myanmar), at a depth of 10.0 km and coordinates 17.0079°, 96.1659°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
