On July 7, 2021 at 20:58 UTC, a magnitude 4.4 intermediate depth earthquake struck 6 km SSW of Suyan, Philippines, at a depth of 173.1 km and coordinates 6.0093°, 125.3602°.
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.
