Shallow M5.7 earthquake hits offshore Oregon
A shallow M5.7 earthquake was registered at 10:53 UTC on June 3, 2026, approximately 138 km (86 miles) west-southwest of Pistol River, Oregon. The earthquake occurred at a depth of 11.0 km (6.8 miles), according to data provided by USGS.
The coordinates for the event were 42.0°N, 126.0°W, placing the epicenter offshore, in the Pacific Ocean, west of the southern Oregon coastline. This region is characterized by its proximity to the Cascadia Subduction Zone, a significant seismic boundary off the Pacific Northwest.
Critical infrastructure in this coastal region of Oregon includes major shipping lanes, fishing areas, and the presence of key energy infrastructure onshore, as well as transportation routes connecting coastal towns.
There is no tsunami threat associated with this earthquake, based on its location and available data.
The significance index for this event is 500 (on a scale that runs through 1 000), reflecting its magnitude and estimated impact, according to USGS.
The region affected by this earthquake is part of the Cascadia Subduction Zone, where the Juan de Fuca Plate is subducting beneath the North American Plate. This tectonic setting is known for its potential to generate powerful earthquakes and associated hazards.
