Felt by 1 person across nearby locations.
On June 19, 2023 at 05:14 UTC, a magnitude 5.2 shallow crustal earthquake struck in the Norfolk Island, Australia region, at a depth of 10.0 km and coordinates -27.8174°, 172.1769°. This earthquake was detected by 51 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.
