On October 3, 2025 at 19:22 UTC, a magnitude 4.7 intermediate depth earthquake struck 68 km W of Kirakira, Solomon Islands, at a depth of 72.2 km and coordinates -10.4660°, 161.2937°. This earthquake was detected by 109 seismic stations with good 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.
