On August 3, 2022 at 15:41 UTC, a magnitude 4.2 shallow crustal earthquake struck 16 km NNE of Sulangan, Philippines, at a depth of 35.0 km and coordinates 11.0726°, 125.8884°.
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.
