On July 3, 2025 at 23:50 UTC, a magnitude 4.1 intermediate depth earthquake struck 28 km ENE of Gamut, Philippines, at a depth of 91.0 km and coordinates 8.5987°, 126.4932°.

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.
