On December 15, 2020 at 15:38 UTC, a magnitude 4.4 shallow crustal earthquake struck 3 km WSW of Tandag, Philippines, at a depth of 36.6 km and coordinates 9.0674°, 126.1647°.
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.
