2023-06-06 23:50:36 UTC (2023-06-06) · approx. 10:50 AM UTC+11 local
On June 6, 2023 at 23:50 UTC, a magnitude 4.0 shallow crustal earthquake struck southeast of the Loyalty Islands, at a depth of 10.0 km and coordinates -23.0705°, 170.4394°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
