M5.0 Earthquake southeast of the Loyalty Islands — June 25, 2022
2022-06-25 11:54:04 UTC (2022-06-25) · approx. 10:54 PM UTC+11 local
On June 25, 2022 at 11:54 UTC, a magnitude 5.0 shallow crustal earthquake struck southeast of the Loyalty Islands, at a depth of 35.0 km and coordinates -22.3892°, 171.6263°. This earthquake was detected by 66 seismic stations with excellent 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.
