On May 23, 2024 at 19:04 UTC, a magnitude 4.1 shallow crustal earthquake struck 109 km WSW of Inuvik, Canada, at a depth of 9.5 km and coordinates 68.1806°, -136.3293°. The nearest populated place is Fort McPherson (population 1,069).

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
