On September 25, 2020 at 20:40 UTC, a magnitude 4.5 intermediate depth earthquake struck near Banda Sea, at a depth of 159.3 km and coordinates -6.6193°, 129.7548°.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
