On September 13, 2020 at 22:16 UTC, a magnitude 4.4 shallow crustal earthquake struck 11 km ESE of Talisay, Philippines, at a depth of 65.6 km and coordinates 6.6823°, 126.1997°.

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.
