On November 30, 2025 at 15:53 UTC, a magnitude 2.8 shallow crustal earthquake struck 8 km ESE of Loomis, Washington, at a depth of 16.4 km and coordinates 48.8027°, -119.5233°.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 215 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 49 m — a useful intuition for the size of the slip patch on the fault.
