On September 5, 2025 at 22:23 UTC, a magnitude 4.1 intermediate depth earthquake struck near Banda Sea, at a depth of 145.3 km and coordinates -6.7457°, 129.7117°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
