A magnitude 6.0 earthquake rattled the Oregon coast late Thursday, but officials said there was no risk of a tsunami and minimal impacts on land.

The quake struck at 7:25 p.m. PST, centered approximately 183 miles west of Bandon, Oregon, according to the U.S. Geological Survey (USGS). It occurred at a depth of 6.2 miles in the Blanco Fracture Zone, a seismically active area where the Juan de Fuca and Pacific tectonic plates interact.

Initial reports from monitoring services such as GlobalQuake and the German Research Centre for Geosciences pegged the magnitude at 6.1, but the USGS revised it to 6.0 after analysis. The agency described it as a potential mainshock in an ongoing sequence, with a fault plane solution indicating strike-slip movement.

Shaking was weak, reaching intensity 3 on the Modified Mercalli Intensity scale in some coastal spots.

USGS received 60 "Did You Feel It?" reports, mostly describing light vibrations.

According to the agency, the earthquake was most likely the potential mainshock of an earthquake sequence.

No damage has been reported so far.

Oregon’s last major earthquake came in 2018 when a 5.3-magnitude earthquake shook Oregon's coast, followed by a 4.4-magnitude aftershock about 40 minutes later. The National Weather Service's Tsunami Alerts account stated then that a "tsunami [is] not expected.”

Chances of a Megathrust Quake?

Researchers have predicted a 37 percent chance of a megathrust earthquake exceeding magnitude 7.1 in the Cascadia Subduction Zone within the next 50 years. That zone, a major offshore tectonic plate boundary stretching from Northern California to British Columbia, could produce devastating quakes and tsunamis.

Thursday's event, however, was in the neighboring Blanco Fracture Zone and not indicative of an imminent Cascadia rupture.

A 2023 report by researchers at the University of Washington (UW) found that a seafloor hole located about 50 miles off Newport, Oregon, and sitting on the 600-mile Cascadia Subduction Zone fault, could cause major earthquakes.

In the study to explain the vent’s nature, researchers suggest that the liquid leaking out of the sea floor hole, which shoots up warm, mineral-rich liquid into the Pacific Ocean, may be acting as a lubricant between the oceanic and continental plates, and that less lubricant means more pressure accumulated to produce a devastating earthquake.

“These strike-slip faults, where sections of ocean crust and sediment slide past each other, exist because the ocean plate hits the continental plate at an angle, placing stress on the overlying continental plate,” Evan Solomon, the study’s co-author and an oceanography professor at UW, said in a press release.

“The megathrust fault zone is like an air hockey table,” the professor explained. “If the fluid pressure is high, it’s like the air is turned on, meaning there’s less friction and the two plates can slip.”

“If the fluid pressure is lower, the two plates will lock,” he added. “That’s when stress can build up.”
