2026-10-02 16:01:39 UTC (3 days ago) · approx. 2:01 AM UTC+10 local
Felt by 517 people across surrounding communities. Maximum shaking intensity MMI 5.9 (strong).
On October 2, 2026 at 16:01 UTC, a magnitude 4.7 shallow crustal earthquake struck 5 km NNE of Korumburra, Australia, at a depth of 10.0 km and coordinates -38.3802°, 145.8401°. The earthquake was reported felt by 517 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 5.9 (strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 27 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 619, making it a moderate-impact event. The nearest populated place is Korumburra (population 4,469).
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
