On September 4, 2026 at 09:25 UTC, a magnitude 3.7 shallow crustal earthquake struck near off the coast of Oregon, at a depth of 10.0 km and coordinates 43.6383°, -129.0824°.

Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
