M4.8 Earthquake in the Macquarie Island region — June 1, 2026
2026-06-01 00:08:42 UTC (54 min ago) · approx. 10:08 AM UTC+10 local
On June 1, 2026 at 00:08 UTC, a magnitude 4.8 shallow crustal earthquake struck in the Macquarie Island region, at a depth of 10.0 km and coordinates -57.8459°, 157.2933°. This earthquake was detected by 15 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
