On September 3, 2026 at 14:15 UTC, a magnitude 4.4 intermediate depth earthquake struck 136 km NNE of Tobelo, Indonesia, at a depth of 100.3 km and coordinates 2.7883°, 128.6396°.

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.
