On September 14, 2021 at 23:44 UTC, a magnitude 5.1 intermediate depth earthquake struck 22 km NE of Lata, Solomon Islands, at a depth of 110.0 km and coordinates -10.5820°, 165.9432°.

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
