On June 9, 2021 at 19:47 UTC, a magnitude 4.4 shallow crustal earthquake struck 17 km NE of Santa Monica, Philippines, at a depth of 51.8 km and coordinates 10.1318°, 126.1527°.
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.
