M3.0 Earthquake 3 km W of Columbia City, Oregon — October 22, 2026
2026-10-22 14:25:19 UTC (2 hours ago) · approx. 6:25 AM UTC-8 local
Felt by 51 people across nearby locations.
On October 22, 2026 at 14:25 UTC, a magnitude 3.0 shallow crustal earthquake struck 3 km W of Columbia City, Oregon, at a depth of 23.4 km and coordinates 45.8847°, -122.8568°. The earthquake was reported felt by 51 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 2.5 (weak). This earthquake was detected by 51 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 154, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Oregon, a region characterized by the southern Cascadia Subduction Zone, with additional seismicity from crustal faults in the Willamette Valley. The nearest mapped fault system is the Cascadia Subduction Zone. View all earthquakes in Oregon.

Where did the earthquake occur?
The earthquake epicenter was located at 45.8847°, -122.8568°, which is 3 km W of Columbia City, Oregon. View all earthquakes in Oregon.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.0 earthquakes can continue for several days and gradually diminish over time.
Has Oregon had earthquakes this big before?
The largest recorded earthquake in Oregon was the M7.3 offshore Brookings earthquake of November 23, 1873. Today's magnitude 3.0 event is significantly smaller than that historical record.
