On December 3, 2023 at 23:15 UTC, a magnitude 4.3 shallow crustal earthquake struck 19 km ENE of Barcelona, Philippines, at a depth of 59.6 km and coordinates 8.2419°, 126.5865°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
