On November 22, 2025 at 23:28 UTC, a magnitude 4.5 intermediate depth earthquake struck 60 km ESE of Kirakira, Solomon Islands, at a depth of 77.2 km and coordinates -10.6594°, 162.4336°. This earthquake was detected by 23 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
