Felt by 35 people across nearby locations.
On June 8, 2026 at 06:43 UTC, a magnitude 2.9 shallow crustal earthquake struck 2 km ESE of Oak Harbor, Washington, at a depth of 25.4 km and coordinates 48.2827°, -122.6093°. This earthquake was detected by 66 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 137, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 294 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 57 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.
