Felt by 11 people across nearby locations.
On December 19, 2025 at 23:29 UTC, a magnitude 2.6 shallow crustal earthquake struck 5 km WSW of Pe Ell, Washington, at a depth of 40.3 km and coordinates 46.5470°, -123.3660°. This earthquake was detected by 71 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 110, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 142 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 41 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Washington, a region characterized by the Cascadia Subduction Zone, where the Juan de Fuca Plate subducts beneath North America and is capable of producing M9+ megathrust earthquakes. The nearest mapped fault system is the Cascadia Subduction Zone. View all earthquakes in Washington.
