2025-09-14 13:25:12 UTC (2025-09-14) · approx. 5:25 AM UTC-8 local
On September 14, 2025 at 13:25 UTC, a magnitude 3.0 shallow crustal earthquake struck 186 km WSW of Port Orford, Oregon, at a depth of 10.0 km and coordinates 42.3847°, -126.7152°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
