On July 17, 2020 at 18:19 UTC, a magnitude 4.1 shallow crustal earthquake struck 64 km W of Kirakira, Solomon Islands, at a depth of 66.4 km and coordinates -10.5009°, 161.3323°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
