On July 31, 2020 at 17:06 UTC, a magnitude 5.2 deep-focus earthquake struck 67 km N of Gizo, Solomon Islands, at a depth of 403.5 km and coordinates -7.4970°, 156.8102°.
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.
