On October 12, 2024 at 23:36 UTC, a magnitude 4.6 shallow crustal earthquake struck near Arctic Ocean, at a depth of 10.0 km and coordinates 80.2639°, -110.7380°. This earthquake was detected by 91 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, 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.
