M4.6 Earthquake south of Australia — May 2, 2026
2026-05-02 19:50:46 UTC (19 hours ago) · approx. 5:50 AM UTC+10 local
On May 2, 2026 at 19:50 UTC, a magnitude 4.6 shallow crustal earthquake struck south of Australia, at a depth of 10.0 km and coordinates -63.0576°, 146.0836°. This earthquake was detected by 21 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
