2023-12-24 23:19:54 UTC (2023-12-24) · approx. 2:19 PM UTC-9 local
On December 24, 2023 at 23:19 UTC, a magnitude 3.4 shallow crustal earthquake struck 275 km W of Langlois, Oregon, at a depth of 10.0 km and coordinates 43.3192°, -127.7945°.
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.
