2026-10-24 22:26:04 UTC (2 hours ago) · approx. 2:26 PM UTC-8 local
On October 24, 2026 at 22:26 UTC, a magnitude 3.9 shallow crustal earthquake struck 209 km WSW of Pistol River, Oregon, at a depth of 10.0 km and coordinates 41.8923°, -126.8682°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
