2022-08-12 19:14:42 UTC (2022-08-12) · approx. 11:14 AM UTC-8 local
On August 12, 2022 at 19:14 UTC, a magnitude 3.1 shallow crustal earthquake struck near off the coast of Oregon, at a depth of 14.8 km and coordinates 43.2924°, -126.6672°.
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.
