On September 7, 2026 at 13:33 UTC, a magnitude 4.3 intermediate depth earthquake struck 79 km NE of Tobelo, Indonesia, at a depth of 235.0 km and coordinates 2.2478°, 128.5045°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
