On November 12, 2025 at 16:26 UTC, a magnitude 4.4 shallow crustal earthquake struck 45 km ESE of Xam Nua, Laos, at a depth of 10.0 km and coordinates 20.2107°, 104.4204°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
