On June 29, 2026 at 11:35 UTC, a magnitude 5.5 shallow crustal earthquake struck 218 km W of Bandon, Oregon, at a depth of 10.0 km and coordinates 43.3828°, -127.0788°. The earthquake was reported felt by 6 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.1 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 62 seismic stations with good location accuracy and was assigned a USGS significance rating of 467, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.5 releases seismic energy equivalent to roughly 3 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.8 km — 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 5.5 earthquake near Bandon, Oregon?

The magnitude 5.5 earthquake that struck 218 km W of Bandon, Oregon on June 29, 2026 at 11:35 UTC had a depth of 10.0 km. It was felt by 6 people with maximum shaking intensity of MMI 3.1 (light). For context, this was a moderate earthquake that could be widely felt.

Where did the earthquake occur?

The earthquake epicenter was located at 43.3828°, -127.0788°, which is 218 km W of Bandon, Oregon. View all earthquakes in Oregon.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.5 earthquakes can continue for days to weeks 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 5.5 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.
