M3.4 Earthquake 131 km W of Gold Beach, Oregon — November 5, 2020
2020-11-05 21:57:06 UTC (2020-11-05) · approx. 1:57 PM UTC-8 local
On November 5, 2020 at 21:57 UTC, a magnitude 3.4 shallow crustal earthquake struck 131 km W of Gold Beach, Oregon, at a depth of 10.0 km and coordinates 42.3230°, -126.0181°.
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.
