2022-11-04 03:52:34 UTC (2022-11-04) · approx. 8:52 PM UTC-7 local
On November 4, 2022 at 03:52 UTC, a magnitude 4.7 shallow crustal earthquake struck in the Bathurst Island region, Nunavut, Canada, at a depth of 10.0 km and coordinates 75.8053°, -104.5144°. This earthquake was detected by 62 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
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.
