On September 29, 2025 at 16:48 UTC, a magnitude 4.1 intermediate depth earthquake struck 4 km NW of Binubusan, Philippines, at a depth of 182.6 km and coordinates 14.0005°, 120.6055°.

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.
