2026-07-13 06:45:31 UTC (2 hours ago) · approx. 5:45 PM UTC+11 local
On July 13, 2026 at 06:45 UTC, a magnitude 5.0 shallow crustal earthquake struck southeast of the Loyalty Islands, at a depth of 10.0 km and coordinates -22.8646°, 171.5471°. This earthquake was detected by 69 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
