On December 29, 2023 at 23:16 UTC, a magnitude 4.0 intermediate depth earthquake struck 30 km NW of Kirakira, Solomon Islands, at a depth of 83.9 km and coordinates -10.2544°, 161.7271°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
