Shallow M5.5 earthquake hits offshore Oregon (Updated)
A shallow M5.5 earthquake was recorded at 11:35 UTC on June 29, 2026, about 218 km (135 miles) west of Bandon, Oregon. The earthquake struck at a depth of 10.0 km (6.2 miles), with the epicenter located at 43.4°N, 127.1°W, in the Pacific Ocean offshore from the Oregon coast.
The coordinates place the earthquake well offshore from the western US coastline, specifically to the west of Bandon, Oregon. This area lies within the offshore region of the Pacific Northwest, far from major population centers, and is characterized by its proximity to underwater features of the Pacific Ocean.
Given its remote, offshore location, the region is primarily influenced by maritime activities, with critical infrastructure such as shipping lanes, fishing zones, and potential offshore energy installations located nearby. Major mainland infrastructure, including ports and transportation networks, are over 200 km (124 miles) distant.
There is no tsunami threat associated with this earthquake, based on its location and available data.
USGS issued a green alert for this event, indicating a low likelihood of casualties or damage. The maximum estimated intensity was III, with four felt reports submitted. The significance index is 466 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.
This portion of the Pacific lies near the boundary of the Juan de Fuca and Pacific Plates, a tectonically active region known for frequent seismic activity due to subduction and transform fault dynamics.
