On September 29, 2025 at 12:42 UTC, a magnitude 3.3 shallow crustal earthquake struck 217 km W of Bandon, Oregon, at a depth of 10.0 km and coordinates 43.4451°, -127.0509°.

Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
