On January 27, 2024 at 22:42 UTC, a magnitude 4.1 shallow crustal earthquake struck 4 km SE of Gamut, Philippines, at a depth of 58.4 km and coordinates 8.5022°, 126.2752°.

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.
