Felt by 12 people across nearby locations.
On June 26, 2026 at 08:06 UTC, a magnitude 2.5 shallow crustal earthquake struck 11 km E of Carnation, Washington, at a depth of 17.1 km and coordinates 47.6295°, -121.7588°. This earthquake was detected by 68 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 99, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 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.
