On November 22, 2024 at 13:10 UTC, a magnitude 4.2 intermediate depth earthquake struck 80 km WSW of Buala, Solomon Islands, at a depth of 77.2 km and coordinates -8.3601°, 158.8924°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
