On July 8, 2023 at 23:15 UTC, a magnitude 2.8 shallow crustal earthquake struck 14 km NW of Saint-Boniface, Canada, at a depth of 10.0 km and coordinates 46.5956°, -76.1192°.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 239 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 52 m — a useful intuition for the size of the slip patch on the fault.
