US EditionMagnitude 5.8 Earthquake Strikes Near Oregon Coast
A 5.8 magnitude quake off Oregon's coast triggered at least five aftershocks; no damage or tsunami risk reported, with less than 1% chance of larger aftershocks, USGS said.
- On the night of Monday, September 8, 2025, a 5.8 magnitude earthquake occurred near the Oregon coast close to the California border.
- The earthquake took place in a tectonically active area off the Oregon coast where the Juan de Fuca Plate is subducting beneath the North American Plate, a region known for frequent smaller offshore seismic events.
- The USGS reported that the earthquake occurred at a depth of roughly 8.5 miles, with its epicenter situated just over 100 miles offshore from Port Orford, Oregon, and was followed by at least 11 smaller quakes ranging in magnitude from 2.7 to 5.1.
- The USGS indicated this event could be the primary earthquake in a sequence and noted that a tsunami is unlikely to occur. Residents reported experiencing mild tremors in areas spanning southern Oregon down to northern California, including regions near Eureka.
- There were neither casualties nor significant destruction reported, and the event underscores the region's vulnerability to stronger, potentially harmful earthquakes, reinforcing the importance of continued monitoring and preparedness measures.
