On October 10, 2025 at 18:59 UTC, a magnitude 4.4 shallow crustal earthquake struck 48 km ESE of Santiago, Philippines, at a depth of 38.0 km and coordinates 7.1992°, 127.0043°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
