On October 6, 2022 at 20:16 UTC, a magnitude 4.4 shallow crustal earthquake struck 149 km ESE of Amahai, Indonesia, at a depth of 52.7 km and coordinates -3.9032°, 130.1395°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
