If you have never heard of axial thread, you will be forgiven. However, the underwater volcano recently announced national news after research shows that it is likely to approach its first eruption in 10 years.
The mountain is about 300 miles from the northern coast of Oregon, where the Pacific and Juan de Fucca plates meet – 4,600 feet below the surface.
“This is at the center of the ocean dispersion, which is on one side of the Juan de fucca tectonic plate, and the other side is the side that enslaves the subduction zone,” said a professor at the University of Washington at McClatchy, studying a volcano.
Fosilized whirlwind in Lava Lake, which was active during 2011. April Axial room eruption.
Will I soon break the axial thread?
Volcano since 1998 Increased three times and the last to 2015. Recently, researchers have noted that the volcano of the magma has blown to almost the level as in previous eruptions.
“The model Bill Chadwick, who is at the Oregon State University, and Scott Nooner in North Carolina, Wilmington, basically noticed … So in 1998, 2011 and 2015 So they have erupted.
The axial thread is where the Juan de Fuca plate meets with the Pacific plate.
If theory is right, it will give insight into how researchers can predict other volcanic eruptions, Wilcock said.
“Why this volcano is interesting is the magma camera located under the volcano is quite shallow.
Another main indicator of a volcano erupts is seismic activity.
After a press release at the end of April, the volcano saw an average of about 200-300 earthquakes per day, which reached 1000 days. This is significantly less than the 2000 earthquake per day the average he saw when the last eruption was observed, and Wilcock said that seismic activity had actually been reduced.
“At the moment, it has actually been slightly reduced to more than 100 to 200 per day, but it varies from week to week,” Wilcock said.
According to Wilcock, he expects the number of earthquakes per day to reach 500 a day until the volcano erupts.
“During these six months, the numbers have fundamentally increased from 500 per day to 2000 per day,” Wilcock said. “So we’re not currently in 2000 a day, but then it was inflated with two feet a year. Now it is slower. So we may not expect as much as much, but I think I would believe at least 500 a day.”
Axial volcano contains many diffuse flow hydrothermal fields and places that support dense animal and microbial communities.
According to Wilcock, experts expect
“I think based on seismicity, we think it could be a little further than other forecasts … But I think everyone would say that if it won’t be this year, it will probably be next year,” said Wilcock.
What happens when the axial thread erupted?
Although volcanic eruption and thousands of earthquakes a day from the northern shores of Oregon may seem frightening, Wilcock said the volcano is too far from the ground to see its effects.
“These earthquakes are really small,” Wilcock said. “They are twins and three. It’s a very small effect, so it will have no effect in the subduction zone for 300 miles.”
In addition, seismic activity around the volcano is not related to land seismic activity, so it is not expected to cause any earthquakes in Washington or Oregon.
This will affect the marine ecosystem, but Wilcock said the affected species would recover quickly.
“When he erupted, you know, many of them are a lot, the bigger the organisms we kill, but they are repeated quite quickly,” Wilcock said. “Then the nutrients leaving the volcano are actually very good for the germs community.”
