2025-02-22 22:20:59 UTC (2025-02-22) · approx. 8:20 AM UTC+10 local
On February 22, 2025 at 22:20 UTC, a magnitude 5.3 shallow crustal earthquake struck 119 km NW of Gizo, Solomon Islands, at a depth of 35.0 km and coordinates -7.4723°, 155.9646°. This earthquake was detected by 55 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
