On August 24, 2023 at 23:38 UTC, a magnitude 4.4 intermediate depth earthquake struck 3 km SW of Taal, Philippines, at a depth of 95.6 km and coordinates 13.8635°, 120.9007°.

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.
