On January 22, 2021 at 00:38 UTC, a magnitude 4.7 shallow crustal earthquake struck 122 km WNW of Buala, Solomon Islands, at a depth of 57.9 km and coordinates -7.5836°, 158.6300°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
