2022-10-14 21:23:02 UTC (2022-10-14) · approx. 1:23 PM UTC-8 local
On October 14, 2022 at 21:23 UTC, a magnitude 3.3 shallow crustal earthquake struck 152 km WNW of Port Orford, Oregon, at a depth of 10.0 km and coordinates 43.0701°, -126.3072°.
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.
