On July 29, 2024 at 20:49 UTC, a magnitude 5.2 shallow crustal earthquake struck southeast of the Loyalty Islands, at a depth of 21.4 km and coordinates -22.3683°, 170.8606°. This earthquake was detected by 56 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
