On January 27, 2026 at 21:25 UTC, a magnitude 3.1 shallow crustal earthquake struck 12 km SSE of Port Orford, Oregon, at a depth of -0.6 km and coordinates 42.6445°, -124.4457°. This earthquake was detected by 34 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 148, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 567 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 77 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.

Common Questions

How strong was the magnitude 3.1 earthquake near Port Orford, Oregon?

The magnitude 3.1 earthquake that struck 12 km SSE of Port Orford, Oregon on January 27, 2026 at 21:25 UTC had a depth of -0.6 km. For context, this was a minor earthquake typically detected only by instruments.

Where did the earthquake occur?

The earthquake epicenter was located at 42.6445°, -124.4457°, which is 12 km SSE of Port Orford, Oregon. View all earthquakes in Oregon.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.1 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 3.1 event is significantly smaller than that historical record.

What should I do after an earthquake?

If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
