On June 6, 2025 at 19:05 UTC, a magnitude 3.9 shallow crustal earthquake struck 190 km NE of Agats, Indonesia, at a depth of 9.0 km and coordinates -4.4150°, 139.4276°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
