On January 3, 2024 at 15:01 UTC, a magnitude 4.4 intermediate depth earthquake struck 1 km WSW of Santa Monica, Philippines, at a depth of 78.3 km and coordinates 10.0148°, 126.0296°.
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.
