On March 17, 2024 at 20:12 UTC, a magnitude 4.3 shallow crustal earthquake struck 101 km E of Barcelona, Philippines, at a depth of 10.0 km and coordinates 8.1630°, 127.3514°.
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.
