On May 10, 2026 at 22:45 UTC, a magnitude 3.8 shallow crustal earthquake struck 227 km SW of Prince Rupert, Canada, at a depth of 10.0 km and coordinates 52.9165°, -132.8378°.

Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
