On January 26, 2021 at 21:04 UTC, a magnitude 4.4 shallow crustal earthquake struck 59 km E of Santa Maria, Philippines, at a depth of 35.0 km and coordinates 8.0318°, 126.9793°.
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.
