On November 18, 2020 at 20:40 UTC, a magnitude 4.3 shallow crustal earthquake struck 92 km NW of Gizo, Solomon Islands, at a depth of 63.7 km and coordinates -7.4134°, 156.3695°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
