On November 27, 2024 at 19:50 UTC, a magnitude 3.2 shallow crustal earthquake struck 8 km NNE of Colstrip, Montana, at a depth of 0.0 km and coordinates 45.9585°, -106.5979°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
