2025-10-13 21:27:59 UTC (2025-10-13) · approx. 1:27 PM UTC-8 local
On October 13, 2025 at 21:27 UTC, a magnitude 3.1 shallow crustal earthquake struck 202 km W of Bandon, Oregon, at a depth of 10.0 km and coordinates 43.4103°, -126.8669°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
