On December 28, 2020 at 20:03 UTC, a magnitude 5.0 shallow crustal earthquake struck 94 km SE of Lata, Solomon Islands, at a depth of 51.8 km and coordinates -11.3759°, 166.3599°.

Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
