On May 5, 2026 at 20:27 UTC, a magnitude 4.3 intermediate depth earthquake struck 40 km NE of Tobelo, Indonesia, at a depth of 126.7 km and coordinates 1.9664°, 128.2837°.

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.
