Deep-sea volcano off Oregon is rumbling again, likely to erupt anytime soon

While predicting the exact timing is tricky, scientists say said an eruption could occur later this year or even tomorrow.

Deep below the Pacific, a restless seafloor volcano off Oregon is showing signs it may soon stir again.

Axial Seamount, a submarine volcano located nearly a mile beneath the ocean surface, is flexing its geologic muscles.

Perched on a hot spot along the Juan de Fuca Ridge, where the Pacific and Juan de Fuca tectonic plates are slowly pulling apart, the volcano is steadily inflating with magma, increasing the frequency of small earthquakes.

Researchers with the National Science Foundation’s Ocean Observatories Initiative, which operates the Regional Cabled Array at the University of Washington, say the uptick in seismic activity suggests an eruption may be near.

“At the moment, there are a couple hundred earthquakes a day, but that’s still a lot less than we saw before the previous eruption,” said William Wilcock, a marine geophysicist at the University of Washington.

While predicting the exact timing is tricky, Wilcock said an eruption could occur anytime between later this year and early 2026 — or even tomorrow.

“I would say it was going to erupt sometime later (this year) or early 2026, but it could be tomorrow, because it’s completely unpredictable.”

Magma rising, pressure building

The researchers also said that the region could witness thousands of small-scale earthquakes as the volcano erupts underwater.

In 2015, 10,000 earthquakes were recorded within 24 hours as magma flowed out of the seafloor volcano for a month, trailing about 25 miles (40 kilometers) underwater. Axial Seamount’s magma chamber has collapsed several times over the years, leaving behind a deep, wide basin known as a caldera.

Despite the extreme conditions, life flourishes here. Hydrothermal vents scattered across the caldera floor release mineral-rich fluids into the icy seawater, creating plumes teeming with microbes — a phenomenon scientists call “snowblowers.”

While past eruptions have wiped out the tiny creatures clustered around these vents, their return is surprisingly swift. Within just a few months, the ecosystem begins to regenerate.

“I think it’s one of the biggest discoveries we’ve made,” said Kelley, a professor of marine geology and geophysics at the University of Washington, in a statement.

“Life thrives in these inhospitable environments, and volcanoes are probably one of the major sources of life in our oceans.”

Ocean feels the shift, land remains unaware Marine life, she said, may feel the seismic shifting after the eruption, but the activity could go unnoticed by people on land.

“It’s not a very explosive event. You won’t see the ash clouds above water, anything like that,” Kelly said.

“It’s like if you put a mile of seawater on top of Kilauea … you may see some fountaining, but that’s it.”

Researchers said that the eruptions are most likely to occur between January and April, as previous events in 1998, 2011, and 2015 took place during this period. Scientists suspect that seasonal gravitational shifts play a role as Earth moves farther from the sun during the early months of the year.

The moon’s pull on ocean tides causes regular changes in pressure along the seafloor, and when magma is already close to the surface, even minor stress variations can make a difference.

Oregon. May it crumble and rent asunder before your eyes.

“Oregon. May it crumble and rent asunder before your eyes.”

You are getting your wish. Many of us fought it for decades. They burned us out. They destroyed our DAMS and farming and infrastructure and ran us out of our homes.
The government has taken our lives. For decades we begged all of you for help and got crickets.

Your State is next.

Funny thing about this earthquake swarm expected around the Axial Seamount in the Rift Zone that is driving the - now overdue! - Mag 8.6 to 9.2 earthquake and tsunami off the BC-WASHINGTON-OREGON-NORCAL Cascadia Fault.

The USGS official earthquake records since 1920 report less than 16 earthquakes of any magnitude within a 100 km radius of the Axial Seamount.

Tens of thousands (literally) north and south of the Seamount, closer to shore and a few hundred further from shore, but less than 16 near the volcano itself.

Further south, just offshore of California’s Cape Mendocino, several dozens of small and medium earthquakes occur every week since the 5 Dec 2024 Mag 7.0 quake. So the Cascadia Fault remains loaded for trouble.

Like shotgun thrown in a fireplace, we just don’t know when it will be set off.

Well, that's a little disappointing. You would in the Hollywood version.

Huh? How are WE supposed to help you fix YOUR Oregon mess? Many of us have huge messes in our own states and many are far worse than Oregon. Don’t tell me about your state’s problems — I’m in CA.

I saw this same story three or four months ago. I guess the rumbling continues. Could be really bad if it blows.

“Bucket Brigade”

The good old days when we still had hope that standing up and fighting might do some good.

It didn’t. I would have been better off staying home with my family baking cookies than fighting for a nation full of people who don’t care. I lost everything including my children trying to protect their rights to a future.

Oregon is beautiful. It’s a shame what was allowed to happen. It’s happening on a massive scale all over the west. Canada too. It’s well planned, orchestrated and funded. People still think it’s about voting. That’s why it’ll never be fixed.
