On September 2, 2026 at 20:14 UTC, a magnitude 2.3 shallow crustal earthquake struck 2 km NE of Dover, Idaho, at a depth of -1.0 km and coordinates 48.2680°, -116.5863°.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 41.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
