A 6.3 magnitude earthquake struck off the coast of Oregon on the morning of Aug. 29, according to the U.S. Geological Survey (USGS).
A tsunami warning was not issued by the U.S. Pacific Tsunami Warning Center.
The quake was located more than 175 miles west of the state’s coast, near the city of Brandon.
Some people in coastal Oregon reported feeling the tremor.
We just had an earthquake. The table was shaking here in Oregon City. 6.4 near Bandon on the coast.

#ALERT: Strong earthquake off the coast of #Oregon this morning in the Cascadia Subduction Zone area.
Residents of the NW should go over their emergency plans today. The CSZ is due for a 9.0+ quake that will devastate infrastructure & communities. This could be a foreshock. https://t.co/aXmZiZuu86

More Earthquakes
Last year, five earthquakes hit off the coast of Oregon in a 24-hour period, and the largest was a 4.5 on the Richter scale.
Before that, hundreds of miles to the north, three strong earthquakes hit off the coast of British Columbia, Canada. The tremors were centered in the Pacific Ocean.
Geophysicist Amy Vaughan told The Associated Press at the time that there may have been some other aftershocks. Vaughan says the quakes were felt onshore. No injuries were reported, she said at the time.
‘The Big One’
Last year, a report said that a 9.0 earthquake could hit off the West Coast of Canada, which could kill thousands of people and trigger massive tsunami waves around the West Coast of North America. What’s more, the waves could even make it to Japan. It’s only a matter of time, they suggested.
“It’s difficult to predict when it will happen again. We do know it’s occurred about 20 times in the past 10,000 years,” Dr. John Clague, an earth sciences professor at Simon Fraser University, told GlobalNews Canada.
The report made reference to a 9.0 magnitude earthquake that hit close to Vancouver Island, British Columbia, in the year 1700.
The quake caused a tsunami that affected the east coast of Japan, and several Native American tribes in the region have oral traditions that speak about a giant earthquake.
“This geologically active region, the Cascadia Subduction Zone, not only hosts erupting volcanoes but also produces megathrust earthquakes capable of generating devastating, ocean-crossing tsunamis. By comparing the tree rings of dead trees with those still living they could tell when the last of these great earthquakes struck the region. The trees all died in the winter of 1699-1700 when the coasts of northern California, Oregon, and Washington suddenly dropped 1-2 m (3-6 feet), flooding them with seawater,” the Pacific Tsunami Warning Center writes.
