M3.0 Earthquake 189 km W of Bandon, Oregon — July 22, 2026
2026-07-22 05:09:58 UTC (4 hours ago) · approx. 9:09 PM UTC-8 local
On July 22, 2026 at 05:09 UTC, a magnitude 3.0 shallow crustal earthquake struck 189 km W of Bandon, Oregon, at a depth of 10.0 km and coordinates 43.3879°, -126.7179°.
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.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.5 mainshock that occurred 22 days ago 226 km W of Langlois, Oregon. Since the mainshock, the USGS has recorded 5 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 3.0 earthquake near Bandon, Oregon?
The magnitude 3.0 earthquake that struck 189 km W of Bandon, Oregon on July 22, 2026 at 05:09 UTC had a depth of 10.0 km. For context, this was a minor earthquake typically detected only by instruments.
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.
Is this the same earthquake as the M5.5 one earlier?
No. This magnitude 3.0 earthquake is an aftershock of the larger magnitude 5.5 mainshock that occurred earlier 226 km W of Langlois, Oregon. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
