On June 27, 2021 at 21:11 UTC, a magnitude 4.5 intermediate depth earthquake struck near Banda Sea, at a depth of 206.7 km and coordinates -6.8333°, 129.3811°.

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.
