On May 25, 2021 at 16:04 UTC, a magnitude 5.0 shallow crustal earthquake struck 153 km ENE of Gizo, Solomon Islands, at a depth of 35.0 km and coordinates -7.7509°, 158.1843°.

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.
