Axial Seamount off Oregon coast eruption potential

In summary, Axial Seamount is an active submarine volcano located on the Juan de Fuca Ridge, approximately 480 km west of Cannon Beach, Oregon. Researchers have forecasted that it may be erupting in 2015 based on previous research that showed the volcano inflates and deflates in a repeatable pattern as it responds to magma being fed into the seamount. The volcano rises to a depth of 1400 m below sea level and any potential eruption could raise the peak by another 1400 meters, bringing it to the surface.

Researchers think Axial Seamount off Northwest coast is erupting – right on schedule

NEWPORT, Ore. – Axial Seamount, an active underwater volcano located about 300 miles off the coast of Oregon and Washington, appears to be erupting – after two scientists had forecast that such an event would take place there in 2015.

Geologists Bill Chadwick of Oregon State University and Scott Nooner of the University of North Carolina Wilmington made their forecast last September during a public lecture and followed it up with blog posts and a reiteration of their forecast just last week at a scientific workshop.

They based their forecast on some of their previous research – funded by the National Science Foundation (NSF) and the National Oceanic and Atmospheric Administration (NOAA), which showed how the volcano inflates and deflates like a balloon in a repeatable pattern as it responds to magma being fed into the seamount.

'Wired' Underwater Volcano May Be Erupting Off Oregon
http://news.yahoo.com/wired-underwater-volcano-may-erupting-off-oregon-194611197.html
An underwater volcano off the coast of Oregon has risen from its slumber and may be spewing out lava about a mile beneath the sea.

Researchers were alerted to the possible submarine eruption of the Axial Seamount, located about 300 miles (480 kilometers) off the West Coast, by large changes in the seafloor elevation and an increase in the number of tiny earthquakes on April 24.

It will be interesting to see if and when it breaks surface.

I wouldn't call that interesting. I would call that :))

Axial Seamount
Axial Seamount is an active submarine volcano on the Juan de Fuca Ridge in the NE Pacific. It rises to a depth of 1400 m below sea level and is located approximately 300 miles off the coast of Oregon.

An eruption that could raise the peak by 1400 meters -- I don't want to see that happen.

I haven't found how deep the ocean is there

if it is already 1400m below sea level ( how tall is it). And obviously another 1400 metre rise will bring it to the surface
get you bids in fast for the purchase of some new real estate :wink:

1. What is Axial Seamount off Oregon coast?

Axial Seamount is an underwater volcano located about 300 miles off the coast of Oregon. It is part of the Juan de Fuca Ridge, a chain of underwater volcanoes in the Pacific Ocean.

2. Is Axial Seamount currently active?

Yes, Axial Seamount is currently active. It has had several eruptions in the past 20 years, with the most recent one occurring in 2015.

3. What is the eruption potential of Axial Seamount?

The eruption potential of Axial Seamount is currently low, but it is constantly monitored by scientists for any signs of increased activity. The last major eruption occurred in 2015, and it is estimated that the volcano could erupt again in the next few decades.

4. What impact would an eruption from Axial Seamount have on the surrounding area?

An eruption from Axial Seamount could potentially have a significant impact on the surrounding area. It could cause underwater earthquakes, landslides, and tsunamis. It could also release large amounts of volcanic gases and chemicals into the water, which could harm marine life.

5. How do scientists monitor the eruption potential of Axial Seamount?

Scientists use a variety of methods to monitor the eruption potential of Axial Seamount. This includes using underwater instruments that measure changes in water temperature and pressure, as well as monitoring seismic activity and changes in the shape of the volcano using sonar technology.
