On September 5, 2026 at 10:03 UTC, a magnitude 2.9 shallow crustal earthquake struck 6 km WNW of Stanley, Idaho, at a depth of 10.0 km and coordinates 44.2332°, -115.0117°.

Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 338 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 60 m — a useful intuition for the size of the slip patch on the fault.
