On August 13, 2022 at 18:45 UTC, a magnitude 4.3 shallow crustal earthquake struck 197 km W of Pistol River, Oregon, at a depth of 10.0 km and coordinates 42.0252°, -126.7645°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
