On October 20, 2021 at 06:38 UTC, a magnitude 5.2 intermediate depth earthquake struck 172 km SE of Lata, Solomon Islands, at a depth of 210.7 km and coordinates -11.9366°, 166.7990°.

Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
