On February 17, 2023 at 17:12 UTC, a magnitude 4.1 deep-focus earthquake struck 237 km SSE of Tabiauan, Philippines, at a depth of 583.0 km and coordinates 4.0014°, 122.5978°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
