On January 30, 2024 at 22:14 UTC, a magnitude 4.2 intermediate depth earthquake struck 173 km SSE of Amahai, Indonesia, at a depth of 193.7 km and coordinates -4.7632°, 129.5790°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
