On October 29, 2025 at 23:13 UTC, a magnitude 4.2 deep-focus earthquake struck 187 km SE of Lata, Solomon Islands, at a depth of 341.3 km and coordinates -12.0976°, 166.8112°.

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.
