On June 21, 2023 at 13:54 UTC, a magnitude 4.7 shallow crustal earthquake struck 120 km SSE of Lata, Solomon Islands, at a depth of 60.1 km and coordinates -11.6513°, 166.3832°. This earthquake was detected by 78 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
