On April 18, 2025 at 23:33 UTC, a magnitude 4.3 intermediate depth earthquake struck 9 km S of San Antonio, Philippines, at a depth of 79.8 km and coordinates 14.8598°, 120.0758°.
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.
