On April 22, 2025 at 16:55 UTC, a magnitude 5.1 shallow crustal earthquake struck 18 km SW of Singleton, Australia, at a depth of 10.0 km and coordinates -32.7000°, 151.0543°. This earthquake was detected by 118 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 612, making it a moderate-impact event.

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
