On July 4, 2021 at 22:13 UTC, a magnitude 4.4 deep-focus earthquake struck near Celebes Sea, at a depth of 544.1 km and coordinates 3.2917°, 122.5766°.
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.
