M5.0 Earthquake west of Macquarie Island — November 27, 2024
2024-11-27 18:06:50 UTC (2024-11-27) · approx. 4:06 AM UTC+10 local
On November 27, 2024 at 18:06 UTC, a magnitude 5.0 shallow crustal earthquake struck west of Macquarie Island, at a depth of 10.0 km and coordinates -59.2025°, 149.2152°. This earthquake was detected by 13 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
