2024-11-21 20:23:05 UTC (2024-11-21) · approx. 12:23 PM UTC-8 local
On November 21, 2024 at 20:23 UTC, a magnitude 3.7 shallow crustal earthquake struck 201 km W of Langlois, Oregon, at a depth of 10.0 km and coordinates 43.2558°, -126.8820°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
