On November 30, 2021 at 23:41 UTC, a magnitude 4.6 shallow crustal earthquake struck 141 km WNW of Buala, Solomon Islands, at a depth of 63.9 km and coordinates -7.8779°, 158.3338°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
