On August 8, 2021 at 14:51 UTC, a magnitude 4.8 intermediate depth earthquake struck 181 km SE of Lata, Solomon Islands, at a depth of 113.0 km and coordinates -12.0698°, 166.7565°.

Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
