On February 21, 2026 at 18:01 UTC, a magnitude 4.6 shallow crustal earthquake struck 111 km SE of Kirakira, Solomon Islands, at a depth of 10.0 km and coordinates -11.1461°, 162.6636°. This earthquake was detected by 44 seismic stations with excellent 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.
