2023-01-18 18:19:07 UTC (2023-01-18) · approx. 10:19 AM UTC-8 local
On January 18, 2023 at 18:19 UTC, a magnitude 4.0 shallow crustal earthquake struck near Northwest Territories, Canada, at a depth of 11.9 km and coordinates 62.2077°, -123.9912°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
