On August 13, 2021 at 21:25 UTC, a magnitude 2.1 shallow crustal earthquake struck 5 km NE of Six Mile, Canada, at a depth of 26.4 km and coordinates 48.4979°, -123.4124°.

Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 21.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 17 m — a useful intuition for the size of the slip patch on the fault.
