On June 24, 2025 at 21:28 UTC, a magnitude 4.3 intermediate depth earthquake struck 16 km SE of Santa Maria, Philippines, at a depth of 86.1 km and coordinates 7.9049°, 126.5621°.

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.
