On October 18, 2022 at 21:19 UTC, a magnitude 4.0 deep-focus earthquake struck near Mindanao, Philippines, at a depth of 384.2 km and coordinates 5.1082°, 124.7121°.

Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
