On December 1, 2025 at 20:05 UTC, a magnitude 5.1 intermediate depth earthquake struck 58 km WNW of Kirakira, Solomon Islands, at a depth of 104.6 km and coordinates -10.2888°, 161.4093°. This earthquake was detected by 73 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
