On October 29, 2021 at 13:48 UTC, a magnitude 4.7 shallow crustal earthquake struck 165 km N of Pangnirtung, Canada, at a depth of 14.1 km and coordinates 67.6223°, -66.0049°.

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.
