On January 2, 2021 at 21:51 UTC, a magnitude 3.4 shallow crustal earthquake struck 244 km W of Bandon, Oregon, at a depth of 10.0 km and coordinates 43.4111°, -127.3976°.

Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
