On October 29, 2024 at 19:55 UTC, a magnitude 4.1 shallow crustal earthquake struck 102 km WNW of Kirakira, Solomon Islands, at a depth of 69.2 km and coordinates -10.2022°, 161.0220°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
