On January 27, 2023 at 20:38 UTC, a magnitude 3.9 shallow crustal earthquake struck 64 km ENE of Prince George, Canada, at a depth of 10.5 km and coordinates 54.1674°, -121.8641°.

Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
