On March 26, 2025 at 22:48 UTC, a magnitude 2.5 shallow crustal earthquake struck 4 km ENE of Oak Bay, Canada, at a depth of 46.0 km and coordinates 48.4725°, -123.2490°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 90.9 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 33 m — a useful intuition for the size of the slip patch on the fault.
