On October 11, 2025 at 21:03 UTC, a magnitude 4.3 shallow crustal earthquake struck 29 km ESE of Baculin, Philippines, at a depth of 42.3 km and coordinates 7.3710°, 126.8364°.0

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
