On July 18, 2020 at 23:28 UTC, a magnitude 4.2 shallow crustal earthquake struck 210 km SE of Sarangani, Philippines, at a depth of 55.2 km and coordinates 4.0369°, 126.7797°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
