On September 30, 2023 at 18:17 UTC, a magnitude 4.6 intermediate depth earthquake struck 91 km SSE of Lata, Solomon Islands, at a depth of 77.9 km and coordinates -11.4659°, 166.1696°. This earthquake was detected by 34 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
