The study found that the Yellowstone supervolcano holds twice as much magma as previously thought

The monster below: Yellowstone’s supervolcano – which would cause mass destruction when it next erupts – holds twice as much magma as previously thought.

  • Previous research found that the caldera of the supervolcano was filled with about 10 percent magma
  • Recent work has found it to be between 16 and 20 percent — twice the amount
  • This was discovered by analyzing the earth’s vibrations throughout the volcano

A new study reveals that the supervolcano in Yellowstone, which could cause mass destruction when it next erupts, holds twice as much magma than previously thought.

The discovery was made by analyzing ground vibrations to create 3D images of the magma chamber below Earth’s formation.

Previous images showed a concentration as low as only 10 percent, but the new research notes that 16 to 20 percent of the caldera contains magma.

The finding “does not indicate the possibility of an eruption in the future,” said Min Chen, an associate professor at Michigan State University (MUS) who was involved in the work.

“Any signs of changes in the system will be picked up by the network of geophysical instruments that continuously monitor Yellowstone,” Chen said in a statement.

Unfortunately, Chen was unable to see the final results. She dies unexpectedly in 2021.

Previous research determined that 10 percent of the supervolcano was filled with liquid magma, but the new study finds it to be between 16 to 20 percent.

Located in Yellowstone National Park in Wyoming and Montana on top of a massive molten reserve, the volcano last erupted 640,000 years ago.

It is one of the largest active continental volcanic fields in the world. Silicate is used to describe magma or igneous rock that is rich in silica.

The images were created by Ross Maguire, a postdoctoral researcher at Michigan State University, who used the technique known as seismic tomography to create the images. But it wasn’t clear enough to really determine the magma capacity.

“I was looking for people who were experts in a specific type of computer-based seismic tomography called waveform tomography,” said Maguire, now an assistant professor at the University of Illinois Urbana-Champaign (UIUC).

Min Chen was truly a world-class expert in this matter.

Chen used her skills with supercomputers to more accurately model Maquire’s images of how seismic waves propagate through the Earth.

The result is sharper, more focused images.

The researchers do not see that this discovery does not mean that the supervolcano is preparing to erupt

“We haven’t seen an increase in the amount of magma,” Maguire said.

“We just saw a clearer picture of what was really there.”

While the study indicates that the supervolcano is not ripe for eruption, if it did, the eruption could blanket the United States in a “nuclear winter.”

This statement was made by experts in 2015 who said that the Yellowstone supervolcano would be a thousand times more powerful than the eruption of Mount St. Helens in 1980.

An in-depth report from HowStuffWorks revealed the process that could occur in the event of a volcano eruption.

It says that a mixture of magma, rock, steam, carbon dioxide, and other gases will eventually come out of the ground, creating a dome shape with cracks.

The dissolved gases then explode, shooting magma across the park.

They say an eruption could kill up to 90,000 people almost instantly and spew a 10-foot layer of molten ash 1,000 miles from the park.

“The ash will block all entry points from the ground, and the spread of ash and gases into the atmosphere will stop most flights, just as it did when a much smaller volcano erupted in Iceland in 2010,” the magazine wrote.

The sulfur gases emitted from the volcano will be released into the atmosphere and mixed with the planet’s water vapor.

“The gaseous haze that could blanket the country would not only dim sunlight — it would also cool temperatures.”

Can an explosion in yellow superfullstone be prevented?

NASA believes that drilling up to six miles (10 kilometers) into the supervolcano under Yellowstone National Park to pump out high-pressure water could cool it.

Despite the fact that the mission will cost $3.46 billion (£2.63 billion), NASA considers it “the most viable solution”.

Using heat as a resource also provides the opportunity to pay for the plan – it can be used to create a geothermal plant, which generates electricity at very competitive rates of around $0.10 (£0.08) per kWh.

But this method of subduing the supervolcano has the potential to backfire and trigger the supervolcano that NASA is trying to prevent.

‘Drilling at the top of the magma chamber’ can be risky; However, digging carefully from the undersides can work.

Even besides the potentially devastating risks, the plan to cool Yellowstone with craters is no easy feat.

Doing so would be a process so slow that one happens at a rate of about one meter per year, which means it would take tens of thousands of years for it to cool completely.

However, there would be no guarantee that it would work for at least hundreds or perhaps thousands of years.
