On May 23, 2025 at 16:36 UTC, a magnitude 4.8 shallow crustal earthquake struck 86 km NNE of Nyngan, Australia, at a depth of 3.0 km and coordinates -30.8036°, 147.3815°. This earthquake was detected by 110 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 377, 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.
