On August 18, 2024 at 18:05 UTC, a magnitude 4.6 shallow crustal earthquake struck 62 km WNW of Merredin, Australia, at a depth of 8.0 km and coordinates -31.2563°, 117.6750°. This earthquake was detected by 36 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 333, 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.
