On January 29, 2026 at 22:17 UTC, a magnitude 3.9 shallow crustal earthquake struck 79 km E of Nabire, Indonesia, at a depth of 10.0 km and coordinates -3.3751°, 136.2126°.

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.
