On March 17, 2022 at 23:05 UTC, a magnitude 4.5 shallow crustal earthquake struck in the Philippine Islands region, at a depth of 10.0 km and coordinates 13.9579°, 119.3870°.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
