2026-08-11 18:10:25 UTC (3 hours ago) · approx. 2:10 AM UTC+8 local
On August 11, 2026 at 18:10 UTC, a magnitude 4.6 shallow crustal earthquake struck near Western Australia, at a depth of 10.0 km and coordinates -31.5799°, 126.5708°. This earthquake was detected by 39 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.
