Felt by 68 people across nearby locations.
On March 5, 2022 at 20:50 UTC, a magnitude 4.0 shallow crustal earthquake struck 3 km SW of Mount Barker, Australia, at a depth of 10.0 km and coordinates -35.0866°, 138.8421°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
