On June 15, 2026 at 20:40 UTC, a magnitude 3.8 shallow crustal earthquake struck 241 km W of Bandon, Oregon, at a depth of 10.0 km and coordinates 43.4725°, -127.3407°.

Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
