On November 6, 2023 at 21:31 UTC, a magnitude 5.3 shallow crustal earthquake struck near Solomon Islands, at a depth of 38.1 km and coordinates -7.4821°, 156.1245°. This earthquake was detected by 169 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
